Get weight measurements between specified dates Args: start_date: Start date in YYYY-MM-DD format end_date: End date in YYYY-MM-DD format
AI agents call get_weigh_ins 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 retrieves historical weight measurement data from Garmin Connect within a date range. It performs a query operation without creating, modifying, deleting, or executing any actions. While the data may be personally sensitive health information, the tool itself is a simple read operation with no destructive or operational side effects.
From the tool's definition Tool name 'get_weigh_ins' and description 'Get weight measurements between specified dates' indicate data retrieval with no modification or side effects. Arguments are date filters for querying existing data.
Documented attack patterns abuse exactly the kind of access get_weigh_ins 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_weigh_ins:
{
"version": "1",
"default": "deny",
"tools": {
"get_weigh_ins": {}
}
}get_weigh_ins is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get weight measurements between specified dates Args: start_date: Start date in YYYY-MM-DD format end_date: End date in YYYY-MM-DD format. 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 get_weigh_ins: 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_weigh_ins 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_weigh_ins 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_weigh_ins. 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_weigh_ins 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.
