Get detailed step data for a given date.
AI agents call get_steps_data to retrieve information from Mcp Garmin without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves health metrics (step data) without side effects. It is a straightforward read operation on personal fitness data. While the data is sensitive from a privacy perspective, the security classification here concerns what the tool itself does operationally. Read operations on data have inherently lower severity than write, execute, or destructive operations.
From the tool's definition The tool is described as 'Get detailed step data for a given date' and is part of an MCP server explicitly advertised as providing 'read-only access to daily health metrics'.
Attacks that exploit this kind of access
Get detailed step data for a given date. It is categorised as a Read tool in the Mcp Garmin MCP Server, which means it retrieves data without modifying state.
Register the Mcp Garmin MCP server in PolicyLayer and add a rule for get_steps_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 Mcp Garmin. Nothing to install.
get_steps_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_steps_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_steps_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_steps_data is provided by the Mcp Garmin MCP server (obrien-matthew/mcp-garmin). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
