List the authenticated athlete
AI agents call list_activities to retrieve information from Strava MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves activity data for the authenticated user without creating, modifying, deleting, or executing any operations. It is a straightforward query operation with minimal security risk, as it only accesses the user's own fitness data that they have already authorized via Strava API authentication.
From the tool's definition Tool name 'list_activities' and description 'List the authenticated athlete' indicate data retrieval with no modification. Server context confirms this queries 'activity history' and 'performance metrics' through natural language—all read operations.
Attacks that exploit this kind of access
List the authenticated athlete. It is categorised as a Read tool in the Strava MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Strava MCP Server MCP server in PolicyLayer and add a rule for list_activities: 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 MCP Server. Nothing to install.
list_activities 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 list_activities 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 list_activities. 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.
list_activities is provided by the Strava MCP Server MCP server (juanlarreapm/strava-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
