Part of the ACR — Agent Composition Records MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents use configure_deep_composition to create or modify resources in ACR — Agent Composition Records. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call configure_deep_composition repeatedly, creating or modifying resources faster than any human could review. Intercept's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach ACR — Agent Composition Records.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Operator privacy control. Enable or disable deep composition capture for this session. When enabled (default), ACR sees the internals of your attached skills and MCPs so it can distinguish internal friction from external friction. When disabled, only top-level component info is sent — ACR no longer sees sub-components. Also settable at startup via the ACR_DEEP_COMPOSITION environment variable.. It is categorised as a Write tool in the ACR — Agent Composition Records MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Add a rule in your Intercept YAML policy under the tools section for configure_deep_composition. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the ACR — Agent Composition Records MCP server.
configure_deep_composition is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the configure_deep_composition rule in your Intercept policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the Intercept policy for configure_deep_composition. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
configure_deep_composition is provided by the ACR — Agent Composition Records MCP server (@tethral/acr-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
