AI agents call list-starred-segments 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 a list of segments that the athlete has starred. It performs a read-only query of the authenticated user's data, returns information without side effects, and does not modify, create, delete, or execute any actions. The severity is low because the data returned is limited to the user's own preference metadata and poses minimal risk of misuse.
From the tool's definition Tool name 'list-starred-segments' and description 'Lists the segments starred by the authenticated athlete' both indicate a query operation that retrieves existing data without modification.

list-starred-segments 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-starred-segments 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-starred-segments. 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-starred-segments 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.
