Get fitness age data Args: date: Date in YYYY-MM-DD format details: If True, include component breakdown (BMI, RHR, vigorous activity) with targets and improvement suggestions
AI agents call get_fitnessage_data 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.
This tool queries and retrieves existing fitness age metrics from Garmin Connect without creating, modifying, or deleting any data. It is a straightforward read operation with no side effects. The context of sibling tools (add_* and create_* methods) confirms this is a retrieval tool separate from data modification.
From the tool's definition Tool name is 'get_fitnessage_data' with description 'Get fitness age data'. The verb 'Get' indicates retrieval only. Arguments are 'date' and 'details' boolean flag for additional breakdown—these control output verbosity, not modifications.
Documented attack patterns abuse exactly the kind of access get_fitnessage_data gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Garmin MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_fitnessage_data:
{
"version": "1",
"default": "deny",
"tools": {
"get_fitnessage_data": {}
}
}get_fitnessage_data is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Register the Garmin MCP Server MCP server in PolicyLayer and add a rule for get_fitnessage_data: 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.
get_fitnessage_data 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_fitnessage_data 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_fitnessage_data. 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_fitnessage_data is provided by the Garmin MCP Server MCP server (taxuspt/garmin_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
