AI agents call get_running_stats 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 tool retrieves running statistics (total runs, distance, elevation, duration, average pace, Eddington number) from Strava. It is a pure read operation that queries existing data without creating, modifying, deleting, or executing any operations. The blast radius of misuse is minimal—an attacker gains visibility into historical activity data but cannot alter or act on it. Classified as Read with low severity.
From the tool's definition Tool name is 'get_running_stats' and description states 'Get overall running statistics' — the verb 'Get' and action of retrieving aggregate statistics indicates data retrieval with no modification or side effects.
Attacks that exploit this kind of access
Get overall running statistics from Strava including total runs, distance, elevation, duration, average pace, and Eddington number. 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_stats: 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_stats 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_stats 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_stats. 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_stats 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.
