AI agents call get_related_docs to retrieve information from Mcp Rtfm without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a search/lookup operation to retrieve related documentation based on metadata criteria. It has no side effects, does not execute code, and does not modify or delete data. It is purely informational retrieval, fitting the Read category for low blast radius if misused by an AI agent.
From the tool's definition 'Find related documentation files based on metadata' - the tool queries and retrieves existing documentation using metadata filtering. No modification, deletion, or execution occurs.

PolicyLayer is an MCP gateway — it sits between your AI agents and Mcp Rtfm, and nothing reaches the server without passing your rules. This is the rule we recommend for get_related_docs:
{
"version": "1",
"default": "deny",
"tools": {
"get_related_docs": {}
}
}get_related_docs is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Find related documentation files based on metadata. It is categorised as a Read tool in the Mcp Rtfm MCP Server, which means it retrieves data without modifying state.
Register the Mcp Rtfm MCP server in PolicyLayer and add a rule for get_related_docs: 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 Mcp Rtfm. Nothing to install.
get_related_docs 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 get_related_docs 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 get_related_docs. 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.
get_related_docs is provided by the Mcp Rtfm MCP server (ryanjoachim/mcp-rtfm). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
