AI agents call get_running_years to retrieve information from Rewind without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read-only query that retrieves historical running activity summaries. No data is created, modified, deleted, or used to execute external operations. It poses minimal security risk as it simply aggregates and returns personal fitness statistics from the Rewind personal data API.
From the tool's definition Tool name 'get_running_years' and description 'Get per-year summary of running activity' indicate data retrieval with no modification.

Get per-year summary of running activity: total runs, distance, elevation, duration, average pace, longest run, and race count for every year on record. It is categorised as a Read tool in the Rewind MCP Server, which means it retrieves data without modifying state.
Register the Rewind MCP server in PolicyLayer and add a rule for get_running_years: 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 Rewind. Nothing to install.
get_running_years 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_running_years 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_running_years. 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_running_years is provided by the Rewind MCP server (rewind-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
