AI agents call get-athlete-stats to retrieve information from Strava without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves statistical summaries (recent, YTD, all-time activity data) about an athlete's past performance. It performs a GET-like query operation with no destructive, executable, or financial implications. The data returned is informational only, and the tool cannot modify, delete, or trigger external actions.
From the tool's definition Tool description states it "Fetches the activity statistics" for an athlete. The verb "fetches" combined with "statistics" (aggregated data) indicates data retrieval with no modification or side effects.
Attacks that exploit this kind of access
Fetches the activity statistics (recent, YTD, all-time) for a specific athlete using their ID. Requires the athleteId obtained from the get-athlete-profile tool. It is categorised as a Read tool in the Strava MCP Server, which means it retrieves data without modifying state.
Register the Strava MCP server in PolicyLayer and add a rule for get-athlete-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 Strava. Nothing to install.
get-athlete-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-athlete-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-athlete-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-athlete-stats is provided by the Strava MCP server (@r-huijts/strava-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
