Download a workout as a FIT file (this will return a message about how to access the file)
AI agents call download_workout to retrieve information from Garmin MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool downloads (retrieves) an existing workout file in FIT format. This is a read operation with no side effects: it does not create, modify, delete, or execute arbitrary operations. The data is exported but not altered. The blast radius is minimal — misuse would only expose the user's own fitness data that is already accessible via other read tools on this server (e.g., get_activity).
From the tool's definition Tool description states it 'Download a workout as a FIT file' — a read operation that retrieves and exports existing fitness data without modifying it.
Attacks that exploit this kind of access
Download a workout as a FIT file (this will return a message about how to access the file). It is categorised as a Read tool in the Garmin MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Garmin MCP Server MCP server in PolicyLayer and add a rule for download_workout: 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 Garmin MCP Server. Nothing to install.
download_workout 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 download_workout 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 download_workout. 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.
download_workout is provided by the Garmin MCP Server MCP server (shubhaankar-sharma/garmin-mcp-railway). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
