Get split summaries for an activity Args: activity_id: ID of the activity to retrieve split summaries for
AI agents call get_activity_split_summaries 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 fitness activity split data (e.g., lap times, segment summaries) from Garmin Connect based on an activity ID. It performs no side effects, creates no data, executes no commands, and cannot delete or transfer funds. The only risk is information disclosure of the user's own fitness data, which is low severity in the context of an MCP server the user has explicitly authorized.
From the tool's definition Tool name 'get_activity_split_summaries' and description 'Get split summaries for an activity' indicate data retrieval with no modification. The verb 'Get' and lack of any parameters that would modify state confirm this is a query operation.
Documented attack patterns abuse exactly the kind of access get_activity_split_summaries 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_activity_split_summaries:
{
"version": "1",
"default": "deny",
"tools": {
"get_activity_split_summaries": {}
}
}get_activity_split_summaries is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get split summaries for an activity Args: activity_id: ID of the activity to retrieve split summaries for. 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_activity_split_summaries: 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_activity_split_summaries 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_activity_split_summaries 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_activity_split_summaries. 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_activity_split_summaries 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.
