Get an overview of the TrueNAS middleware architecture and repository structure
AI agents call truenas_overview to retrieve information from TrueNAS Middleware MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves architectural documentation and repository structure information. It performs a query-like operation to expose categorized resources and documentation from CLAUDE.md files. No data is modified, deleted, executed, or committed. The blast radius if misused is minimal since it only provides informational content about the codebase structure.

Get an overview of the TrueNAS middleware architecture and repository structure. It is categorised as a Read tool in the TrueNAS Middleware MCP Server MCP Server, which means it retrieves data without modifying state.
Register the TrueNAS Middleware MCP Server MCP server in PolicyLayer and add a rule for truenas_overview: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches TrueNAS Middleware MCP Server. Nothing to install.
truenas_overview is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the truenas_overview rule in your PolicyLayer 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 PolicyLayer policy for truenas_overview. 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.
truenas_overview is provided by the TrueNAS Middleware MCP Server MCP server (sonicaj/tn_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
