Bottom Line Up Front: build or buy agentic infrastructure in 2026
Bottom Line: For most enterprises in 2026, the answer is hybrid — buy managed orchestration primitives for bounded, low-sensitivity workflows and build the internal control plane that governs policy, identity, and audit. Pure-build paths require substantial annual platform team headcount and cloud costs and add roughly nine months to time-to-market. Pure-buy paths via managed agentic infrastructure like AWS Bedrock AgentCore or OpenAI's Responses API run lower annual SaaS and usage spend than internal platforms, but surrender data sovereignty and embed vendor-specific execution logic into your critical paths. The build vs buy inflection point is not primarily a cost argument — it is a data-sensitivity and control argument that cost analysis validates after the fact. Enterprises handling regulated data, proprietary model orchestration logic, or tightly coupled legacy systems should bias toward building the core orchestration layer; everyone else should evaluate whether the annual R&D overhead of the build path delivers proportional Enterprise LLM ROI within a realistic two-year horizon.
What changed in the enterprise agent stack
Agentic infrastructure ceased to be a pilot curiosity in 2025 and became a platform-layer decision in 2026. The signal is unambiguous: the January 2026 arXiv paper "The Orchestration of Multi-Agent Systems: Architectures, Protocols, and Enterprise Adoption" formally treated enterprise multi-agent orchestration as a research domain rather than a prototype pattern. OpenAI retired the Assistants API toward a planned mid-2026 sunset, replacing it with the Responses API — described by OpenAI as "our new API primitive for building agents". These are platform-scale adoption signals, not pilot signals.
The business consequence is that infrastructure decisions made today carry multi-year lock-in risk. Teams still running Assistants API workflows face a forced migration before the mid-2026 sunset. The older SaaS-era advice — "buy a wrapper, ship an assistant, iterate later" — breaks down when the wrapper itself is being deprecated.
Pro Tip: If your team has any production dependency on the OpenAI Assistants API, treat the mid-2026 sunset as a hard migration deadline, not a soft recommendation. The Responses API is the forward-compatible surface; rebuild orchestration logic there before the deprecation forces an emergency migration that resets your ROI clock.
Why orchestration moved from pilot tool to platform layer
The April 2026 arXiv paper "Context Kubernetes" frames enterprise knowledge delivery for agents — permissions, freshness, scoping — as structurally analogous to container orchestration: a problem complex enough to demand dedicated platform thinking. That framing is accurate. When agents need to read from Postgres, write to Slack, invoke internal APIs, and hand off tasks between sub-agents, the orchestration layer is no longer a thin adapter — it is the enforcement boundary for access control, rate limits, and audit trails.
The shift explains why older enterprise SaaS-era ROI benchmarks are unreliable guides. Those benchmarks assumed single-task assistants with shallow integrations. A 2026 agentic platform handles multi-step, multi-tool, multi-model workflows with session state and authorization requirements that did not exist in the prior generation.
| Dimension | Pre-2025 Assistant SaaS | 2026 Agentic Platform |
|---|---|---|
| Execution model | Single-turn or short thread | Multi-step, stateful, multi-agent |
| Integration depth | Surface-level API call | Tool-call chains with auth + audit |
| Failure modes | Bad response | Runaway tool calls, data exfiltration |
| Primary cost driver | Per-query token spend | Platform team + infra + token spend |
| Vendor lock-in surface | Model API | Orchestration runtime + data connectors |
Where MCP, A2A, and internal APIs fit
Model Context Protocol (MCP) is Anthropic's open standard for connecting AI systems with data sources: "It provides a universal, open standard for connecting AI systems with data sources, replacing fragmented integrations with a single protocol." MCP is the connective tissue between an orchestration layer and your Postgres instance, Slack workspace, or internal REST API. Its November 2025 spec update added asynchronous operations, statelessness, server identity, and an official Registry for discovering available MCP servers — moving it from a proof-of-concept protocol toward an enterprise-grade integration standard.
Agent-to-Agent (A2A) protocols handle the handoff and delegation layer above MCP — how one agent invokes another with a scoped task and receives a structured result. AWS exposes this surface through the bedrock-agent-runtime data plane, which handles agent invocation, flow execution, and knowledge base queries as distinct API operations.
| Protocol Layer | Role | Primary Standard / Implementation | Key 2026 Constraint |
|---|---|---|---|
| Data connectivity | Connect agents to data sources | MCP (Anthropic open standard) | Server identity + statelessness still maturing |
| Agent orchestration | Coordinate multi-step task execution | LangGraph 0.2, Bedrock Agents, Responses API | Vendor-specific runtime lock-in |
| Agent-to-agent delegation | Sub-agent invocation and result handoff | A2A patterns, Bedrock Agent Flows | Auth boundary design is organization-specific |
| Internal API access | Wrap proprietary services as tools | JSON Schema + OpenAPI, custom MCP servers | Governance and rate-limiting must be built internally |
The 2026 vendor landscape for agentic infrastructure
The managed-platform market for agentic infrastructure has consolidated around three credible tiers: hyperscaler managed runtimes (AWS Bedrock AgentCore, Azure AI Foundry Agents), foundation model provider primitives (OpenAI Responses API, Anthropic Claude tool use), and open-source orchestration frameworks self-hosted on your own cloud infrastructure (LangGraph 0.2, custom MCP servers). Each tier presents distinct build vs buy trade-offs and carries specific risks for enterprise buyers.
The core risk of buying is not cost — it is control-plane dependence. AWS positions Bedrock AgentCore as a platform to "build, deploy and operate highly capable agents securely, at scale using any framework and model – no infrastructure management required." That "no infrastructure management" guarantee is also a "no infrastructure control" constraint. Your agent runtime, memory store, and tool execution environment live inside AWS's control plane, not yours.
| Vendor / Platform | Runtime Model | Data Sovereignty | Typical Annual Cost Range | Primary Lock-in Risk |
|---|---|---|---|---|
| AWS Bedrock AgentCore | Fully managed, multi-model | AWS region (not your VPC by default) | Scenario estimate: $60k–$180k | Bedrock control plane, AWS-specific APIs |
| OpenAI Responses API | Managed, OpenAI models only | OpenAI data processing agreement | Scenario estimate: $40k–$120k | GPT model family, Responses API surface |
| LangGraph 0.2 (self-hosted) | Self-hosted on your cloud | 100% — your infrastructure | Scenario estimate: $200k–$450k | Framework version dependency, migration burden |
| Custom MCP + orchestration | Fully self-built | 100% | Scenario estimate: $250k–$500k | Internal maintenance, protocol evolution tracking |
Managed agentic SaaS platforms
For a medium-usage enterprise workflow, managed agentic SaaS platforms deliver a production-ready runtime with no infrastructure provisioning, built-in model routing, managed memory, and tool-call execution at scale. AWS Bedrock Agents "uses the reasoning of foundation models, APIs, and data to break down user requests, gathers relevant information, and efficiently completes tasks." OpenAI's Responses API is positioned as the forward surface for building agents, which makes it the cleaner choice for new development that needs a hosted runtime.
The cost model is usage-based and contains several non-obvious price drivers. OpenAI charges web search content tokens as a fixed block of 8,000 input tokens per call on supported models — a cost that compounds quickly in research-heavy agent workflows. GPT-5.5 sessions exceeding 272K input tokens are priced at 2× input and 1.5× output for the full session. Regional processing endpoints carry a 10% uplift. These are not edge cases: any production agent doing document retrieval, memory lookups, or multi-turn reasoning will routinely cross these thresholds.
| Platform Feature | AWS Bedrock AgentCore | OpenAI Responses API |
|---|---|---|
| Model flexibility | Multi-model (Anthropic, Meta, Mistral, Amazon) | OpenAI models only |
| Built-in tool types | Knowledge bases, code interpreter, API connectors | Web search, file search, computer use |
| Pricing model | Per-invocation + token spend | Token-based + per-tool billing blocks |
| Observability built-in | CloudWatch integration | OpenAI usage dashboard |
| Compliance certifications | SOC 2, HIPAA, FedRAMP (varies by region) | SOC 2, limited HIPAA support |
Internal platform teams and self-hosted orchestration
The annual figure for internal platform ownership breaks down into staffing, cloud infrastructure, and toolchain licensing. A minimal viable internal platform team for 2026 agentic infrastructure usually requires multiple senior platform engineers, a DevOps/MLOps engineer, and fractional security and compliance time. That staffing baseline often dominates the budget before cloud costs are added.
Self-hosted orchestration stacks built on LangGraph 0.2 require teams to own context-window management, session state, tool-call authorization, rate limiting, and observability — all of which managed platforms abstract away. Teams must also engineer around OpenAI's pricing thresholds directly: the 272K input-token session multiplier affects any workflow using long document context, and the Assistants API sunset forces migration overhead for teams that built on that surface before Responses API matured.
| Cost Category | Annual Range | Notes |
|---|---|---|
| Platform engineering FTE (2–3 engineers) | $260k–$440k | Loaded cost including benefits, equity |
| Cloud infrastructure (compute, storage, networking) | $40k–$80k | GPU inference excluded — model API calls billed separately |
| Toolchain and observability licenses | $15k–$40k | LangSmith, Datadog, etc. |
| Token spend (model API calls) | $20k–$80k | Highly workload-dependent |
| Total internal path | $335k–$640k | Before security/compliance overhead |
Where security reviewers push back hardest
Tool-call authorization is the security team's primary escalation point on agentic infrastructure. The attack surface is qualitatively different from traditional API security: an agent with computer-use capability, web search access, and file-system read/write can cause significantly more damage from a compromised or misdirected tool call than a traditional API client. OpenAI's Responses API includes built-in tools for web search, file search, and computer use — each of which requires explicit authorization scope that most teams underspecify in their initial deployments.
MCP's November 2025 spec update added server identity and statelessness explicitly because the prior version lacked reliable mechanisms for tracing which server handled a given tool call. Anthropic notes: "The November 25th spec release introduced many new features, including asynchronous operations, statelessness, server identity, and official extensions." These additions directly address audit traceability — but only if implementations enforce them.
Pro Tip: Security reviewers should demand that every MCP server in your environment exposes a stable server identity claim, and that your orchestration layer logs both the server identity and the full tool-call payload — not just the agent's intent. Rate limiting should be enforced at the MCP server boundary, with per-session and per-minute limits recorded alongside the call trace.
Cost and ROI framework for build vs buy decisions
The competitive gap in most build vs buy analyses is the absence of a quantitative TCO framework that accounts for developer FTE costs, SaaS seat licensing, and the usage-based pricing modifiers that vendors disclose but analysts omit. The framework below covers all four cost vectors: people, platform, tokens, and hidden operational overhead.
Enterprise LLM ROI analyses that compare only token spend to productivity gains miss 60–70% of the true cost differential. People and process costs — migration overhead, security review cycles, observability tooling — dominate the TCO comparison at enterprise scale.
| Cost Vector | Buy (Managed SaaS) | Build (Internal Platform) |
|---|---|---|
| People | 0.5–1 FTE integration/ops | 2–4 FTE platform engineers |
| Platform / licensing | $50k–$150k/yr | $15k–$40k/yr (toolchain only) |
| Cloud infrastructure | Included in SaaS pricing | $40k–$80k/yr additional |
| Token spend | Usage-based, price-modifier-dependent | Usage-based, same models |
| Migration/upgrade cycles | Vendor-managed (but forced) | Self-managed (but controlled) |
| Security review overhead | 1–2 weeks/quarter | 2–4 weeks/quarter |
A realistic annual cost model for each path
AWS Bedrock AgentCore's "no infrastructure management required" pricing is usage-based: you pay per agent invocation and per token consumed through the managed runtime, plus underlying foundation model costs. The managed platform eliminates the fixed FTE cost but introduces usage volatility — agentic workflows with long context windows or frequent tool calls can exceed projected spend quickly due to OpenAI's session multiplier pricing (2× input / 1.5× output above 272K tokens) or the fixed 8,000-token billing block for web search calls.
The internal build path's annual cost is relatively stable (dominated by fixed FTE costs) but carries a steeper initial ramp: teams report 6–12 months before the platform reaches production reliability, compared to 4–8 weeks for managed platform onboarding.
| Scenario | Year 1 Total Cost | Year 2 Total Cost | Break-even vs. Buy |
|---|---|---|---|
| Buy: Bedrock AgentCore (medium usage) | $90k–$150k | $100k–$180k | N/A (baseline) |
| Buy: OpenAI Responses API (medium usage) | $70k–$120k | $80k–$140k | N/A (baseline) |
| Build: LangGraph + internal team (3 FTE) | $380k–$520k | $320k–$460k | Unlikely within 3 years at medium scale |
| Build: Custom MCP + orchestration (4 FTE) | $450k–$640k | $380k–$560k | Only justified by sovereignty or proprietary logic |
| Hybrid: Internal policy plane + managed execution | $180k–$280k | $160k–$250k | 18–24 months vs. full-buy |
How to estimate payback period and time-to-value
The OpenAI Assistants API sunset mid-2026 introduces a concrete time variable that most payback analyses ignore: teams with existing Assistants API workflows must absorb migration cost before their payback clock starts. That migration — re-implementing thread management, tool definitions, and run orchestration against the Responses API — typically costs 4–8 weeks of senior engineering time before new development can resume.
For new greenfield deployments, the buy path (Bedrock AgentCore or Responses API) reaches production in 4–8 weeks. The build path requires 6–12 months for the platform to stabilize. The time-to-market gap is large enough to materially delay realized productivity gains for a workflow that automates material labor.
| Path | Time to First Production Agent | Time to Platform Stability | Implied Delay Cost ($500k/yr workflow) |
|---|---|---|---|
| Buy (managed SaaS) | 4–8 weeks | 8–12 weeks | $0 (baseline) |
| Hybrid (internal policy + managed execution) | 6–10 weeks | 3–4 months | ~$50k–$80k |
| Build (full internal) | 12–20 weeks | 6–12 months | $230k–$375k |
Which hidden costs usually get missed
Four categories of hidden cost consistently escape initial TCO models.
MCP protocol maintenance. MCP is not a frozen standard. Anthropic's November 2025 spec update added asynchronous operations, statelessness, and server identity. Teams that built MCP server implementations before that release must retrofit those features or accept a security and auditability gap. Each spec revision carries 2–6 weeks of engineering maintenance per MCP server in your environment.
Observability and compliance instrumentation. AWS Bedrock's separation of the agent control plane and the bedrock-agent-runtime data plane means compliance teams must instrument both layers to achieve complete audit coverage. Teams routinely underestimate this by one full engineering quarter.
Token spend volatility from billing-block pricing. OpenAI's fixed 8,000-input-token billing block for web search calls creates cost spikes in agent workflows that invoke search frequently. Financial models that price only on average token counts will underestimate actual spend for search-heavy workflows.
Platform sprawl governance. Teams that adopt multiple managed agent surfaces without a unified internal contract for identity, logging, and policy enforcement accumulate governance debt. Each additional managed runtime (Bedrock for one team, Responses API for another) doubles the security review surface and fragments audit log pipelines.
| Hidden Cost Category | Typical Missed Amount (Annual) | Who Gets Surprised |
|---|---|---|
| MCP server protocol maintenance | $20k–$60k (engineering time) | Teams that built pre-Nov 2025 MCP servers |
| Observability/compliance instrumentation | $30k–$80k (engineering + tooling) | Regulated industries |
| Token billing-block volatility | 40–70% cost overrun on projected token spend | Search-heavy agent workflows |
| Platform sprawl governance debt | $40k–$120k (security review, audit tooling) | Orgs with multiple independent agent teams |
Decision framework: when to build, buy, or hybridize
The build vs buy decision for agentic infrastructure is primarily driven by four variables: data sensitivity, required orchestration control, legacy integration depth, and organizational capacity to own a platform. Enterprise LLM ROI is a secondary validation check, not the primary driver.
MCP's design as an open standard enables hybrid architectures that standardize commodity data-source integrations while retaining internal control over orchestration policy: "It provides a universal, open standard for connecting AI systems with data sources, replacing fragmented integrations with a single protocol." AWS Bedrock's fully managed runtime supports bounded buy decisions where sovereignty is not the constraint. The practical decision space is therefore three-way, not binary.
DecisionMatrix
| Decision Variable | Build | Buy | Hybrid |
|---|---|---|---|
| Data sensitivity | Regulated / sovereign data | Public or low-sensitivity data | Mixed — some regulated, some not |
| Orchestration control | Proprietary routing / policy logic | Standard task patterns | Policy internal, execution external |
| Legacy integration depth | Deep coupling to on-prem or sensitive systems | Cloud-native or greenfield | Legacy data layer stays internal |
| Time-to-market pressure | Low — can absorb 9-month delay | High — needs production in weeks | Medium |
| Organizational platform capacity | Existing ML platform team | No dedicated platform engineering | Small platform team, bounded scope |
| Annual budget for platform | $300k+ available | Under $150k available | $150k–$300k available |
Choose build when data residency requirements prevent any customer or operational data from transiting a vendor's managed control plane, or when the orchestration logic itself is a proprietary competitive asset. Financial services, healthcare, and defense-adjacent organizations handling PII, PHI, or classified signals fall into this category without exception.
Choose buy when the use case is bounded in scope and does not handle regulated data, time-to-market matters more than deep customization, and the organization lacks platform engineering capacity to own the runtime.
Choose hybrid when the enterprise needs sovereignty over who-can-do-what without the cost of building the full execution layer. Internal policy and identity can stay internal while AWS Bedrock or Responses API handles tool execution and model calls under a contract governed by internal policy.
Choose build when sovereignty and proprietary logic dominate
Build the orchestration layer internally when data residency requirements prevent any customer or operational data from transiting a vendor's managed control plane, or when the orchestration logic itself is a proprietary competitive asset. Financial services, healthcare, and defense-adjacent organizations handling PII, PHI, or classified signals fall into this category without exception.
The April 2026 "Context Kubernetes" paper articulates the technical argument precisely: delivering the right knowledge with the right permissions and freshness across an organization requires the same kind of platform-layer thinking that container orchestration brought to compute. That problem cannot be outsourced if the permissions model is itself proprietary.
MCP servers for Postgres, internal REST APIs, and on-prem data systems can be self-hosted — MCP is an open standard, not a vendor-controlled runtime. The implementation burden is real: permissioning, freshness management, server identity enforcement, and protocol-change maintenance all fall to your team. Budget accordingly.
Choose build when: - Data sovereignty requirements prohibit vendor data plane transit - Orchestration logic encodes proprietary business rules that cannot be exposed via SaaS configuration - Legacy systems require tight coupling that managed platforms cannot accommodate without a custom connector layer - Regulatory audit requirements demand complete control over every log produced by the agent runtime
Choose buy when speed and bounded scope matter more
Managed platforms win decisively when the use case is bounded (a defined set of tools, a single team, a contained workflow) and time-to-market pressure is high. AWS Bedrock AgentCore reaches production in weeks because it eliminates infrastructure provisioning, model routing, memory management, and tool-execution plumbing. OpenAI's Responses API is the forward surface for new agent development, demonstrating the platform's operational maturity.
The buy path is also correct for organizations without an existing ML platform team. Hiring multiple senior platform engineers to build internal orchestration infrastructure when Bedrock or Responses API would serve the use case adequately is a premium that delivers negative ROI unless the sovereignty or control arguments are present.
Choose buy when: - The use case is bounded in scope and does not handle regulated data - Time-to-market matters more than deep customization - The organization lacks platform engineering capacity to own the runtime - The workflow's token volume stays below pricing-threshold inflection points (below 272K input tokens per session, minimal web search tool use)
Choose hybrid when core orchestration should stay internal
The hybrid path — internal policy and identity plane, managed execution runtime — suits enterprises that need sovereignty over who-can-do-what without the cost of building the full execution layer. In practice, this means: your internal orchestration layer manages agent identity, task authorization, rate limiting, and audit logging; AWS Bedrock or Responses API handles the actual tool execution and model calls under a contract governed by your internal policy.
MCP's open standard design supports this pattern directly. Internal MCP servers for sensitive data sources stay on your infrastructure. Commodity data sources (public web, non-sensitive knowledge bases) route through managed platform connectors. The AWS Bedrock bedrock-agent-runtime data plane handles agent invocation; your internal policy engine handles access decisions before any invocation reaches Bedrock.
The hybrid path costs less than full build and more than full buy in year two, and achieves production stability in 3–4 months, a reasonable compromise for organizations with moderate sovereignty requirements and limited platform capacity.
Risks, counterarguments, and failure modes
The build path's primary failure mode is underestimating total ownership cost and then abandoning the effort mid-build — leaving the organization with neither a functioning internal platform nor a managed-platform deployment. The buy path's primary failure mode is discovering, after deep integration, that the vendor's roadmap diverged from organizational requirements.
Watch Out: The build path's nine-month time-to-market gap is an average. Teams that understaff the initial platform build routinely experience 14–18 month delays before the platform reaches production reliability. At that timeline, the delayed productivity realization often exceeds the cumulative cost of the managed platform alternative.
Security, compliance, and tool authorization
The authorization model for agent tool calls is architecturally different from REST API authorization, and security reviews that apply the same threat model will miss the critical vectors. A compromised or misdirected agent with computer-use and web-search capabilities can exfiltrate data, exhaust API quotas, or modify system state through chains of individually authorized tool calls that each appear benign in isolation.
MCP's November 2025 spec update added server identity and statelessness precisely to address the traceability gap: without server identity, an audit log can confirm that a tool call was made but cannot confirm which MCP server handled it. The AWS Bedrock bedrock-agent-runtime data plane provides dedicated runtime APIs for agent invocation that security teams should instrument with CloudWatch logging at the API Gateway layer, not just at the application layer.
Watch Out: Rate limiting must be enforced at the MCP server boundary, not only at the LLM API. Prompt injection attacks can cause an agent to issue many tool calls within a single session, exhausting downstream service quotas before token-level rate limits trigger. Every production MCP server should enforce per-session and per-minute call limits independently of the orchestration layer.
Lock-in, roadmap drift, and platform sprawl
OpenAI's Assistants API sunset is the most concrete 2026 example of vendor roadmap drift imposing migration cost on buyers: "The Responses API is our new API primitive for building agents" — meaning the prior API surface is being deprecated, and teams built on it must migrate on the vendor's schedule. AWS Bedrock's "fully managed" positioning similarly means AWS controls runtime changes, API versioning, and deprecation timelines.
MCP itself illustrates protocol evolution risk: the November 2025 spec added asynchronous operations, statelessness, and server identity. These are meaningful architectural changes that require implementation updates, not configuration tweaks. Teams that treat MCP as a stable integration standard rather than an evolving protocol will accumulate implementation debt.
Platform sprawl risk is organizational rather than technical: when multiple teams independently adopt different managed agent runtimes without a unified internal contract for identity, logging, and policy enforcement, the result is fragmented audit coverage and duplicated compliance overhead. A central internal policy layer — even a lightweight one — prevents this proliferation from becoming a governance liability.
Watch Out: Vendor contract terms for managed agentic platforms typically include data processing agreements that govern where agent execution and memory storage occur. These terms can conflict with data-residency requirements that the security team approved for the organization's LLM usage policy. Review agent-runtime data processing agreements separately from model API data processing agreements — they often have different terms.
FAQ on build vs buy agentic infrastructure
Pro Tip: Before committing to either path, run a two-week spike: deploy one production-representative agent workflow on a managed platform (Bedrock or Responses API) and document every constraint you hit — data residency, authorization model, observability gaps, billing surprises. That spike produces the decision inputs strategy documents cannot: actual friction data from your specific workload shape and security requirements.
Should you build or buy agentic AI infrastructure?
Build when data sovereignty, proprietary orchestration logic, or deep legacy integration is the dominant constraint. Buy when time-to-market and bounded scope dominate. Default to hybrid — internal policy plane, managed execution runtime — when both concerns are present and budget is moderate.
What is the ROI of building AI agents in-house?
The ROI of the full-build path is negative at medium scale when measured against a two-year horizon. The annual platform cost requires a workflow automation value that most organizations cannot attribute with confidence before 18 months of production operation. For large-scale deployments handling high-sensitivity data, the build path becomes ROI-positive by year three as the platform amortizes across multiple agent use cases. OpenAI's GPT-5.5 context window tops 1.05M tokens, which reduces per-query costs for long-context workflows — but only if your internal platform engineers correctly implement context management against the 272K-token pricing multiplier threshold.
What are the risks of buying agentic AI platforms?
The three material risks are: (1) roadmap drift forcing unplanned migrations (OpenAI's Assistants API sunset is a live example), (2) data processing agreement terms that conflict with regulatory requirements, and (3) billing model opacity — fixed token billing blocks for tool use and session-level pricing multipliers create cost volatility that usage dashboards often do not surface until an invoice arrives.
When does it make sense to build an orchestration layer?
Build the orchestration layer when the policy, identity, and audit requirements for your agent workflows cannot be satisfied by the configuration surface of managed platforms. "Amazon Bedrock Agents is a fully managed service that enables you to build and configure autonomous agents in your applications" — the "configure" boundary is the key qualifier. If your requirements exceed what configuration can enforce, the managed runtime is the wrong host for your control plane.
