Get aggregate statistics for the entire APIs.guru directory, e.g. total number of APIs, providers, endpoints, and specs (numAPIs, numEndpoints, numSpecs, ...). Use this for a high-level summary of how much public-API coverage the directory has.
AI agents call get_metrics to retrieve information from Mcp Apis Guru without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only reads and returns statistical metadata about the APIs.guru directory. It has no side effects, cannot modify or delete data, and does not execute code or trigger external operations. It is a straightforward data retrieval operation with minimal security risk.
From the tool's definition Tool retrieves 'aggregate statistics' and 'high-level summary' of the directory. No modification, deletion, or execution of external operations occurs. The description explicitly states it is for querying metrics (numAPIs, numEndpoints, numSpecs).

Get aggregate statistics for the entire APIs.guru directory, e.g. total number of APIs, providers, endpoints, and specs (numAPIs, numEndpoints, numSpecs, ...). Use this for a high-level summary of how much public-API coverage the directory has. It is categorised as a Read tool in the Mcp Apis Guru MCP Server, which means it retrieves data without modifying state.
Register the Mcp Apis Guru MCP server in PolicyLayer and add a rule for get_metrics: 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 Apis Guru. Nothing to install.
get_metrics 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_metrics 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_metrics. 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_metrics is provided by the Mcp Apis Guru MCP server (https://gateway.pipeworx.io/apis-guru/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
