Get body metrics with skinfolds.
AI agents call get_body_metrics to retrieve information from MCP Logger without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves existing body metric data (measurements and skinfold measurements) from the fitness tracking database. It performs no side effects, does not modify data, does not execute commands, and does not delete anything. It is a straightforward read operation consistent with other query tools on this server (get_exercise_history, get_nutrition_day, get_last_workout).
From the tool's definition Tool name 'get_body_metrics' and description 'Get body metrics with skinfolds' indicate a query/retrieval operation with no modification or deletion of data.

Get body metrics with skinfolds. It is categorised as a Read tool in the MCP Logger MCP Server, which means it retrieves data without modifying state.
Register the MCP Logger MCP server in PolicyLayer and add a rule for get_body_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 Logger. Nothing to install.
get_body_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_body_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_body_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_body_metrics is provided by the MCP Logger MCP server (johnzolton/mcp-logger). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
