Get the authenticated athlete's recent activities.
AI agents call get_activities to retrieve information from MCPacer without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns data about running activities from Strava for an authenticated user. It performs no side effects, creates no resources, executes no external operations, and causes no data loss.
From the tool's definition Tool name is 'get_activities' with description stating it retrieves 'the authenticated athlete's recent activities.' The verb 'get' and the retrieval-focused description indicate a read-only operation.
Documented attack patterns abuse exactly the kind of access get_activities gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and MCPacer, and nothing reaches the server without passing your rules. This is the rule we recommend for get_activities:
{
"version": "1",
"default": "deny",
"tools": {
"get_activities": {}
}
}get_activities is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get the authenticated athlete's recent activities. It is categorised as a Read tool in the MCPacer MCP Server, which means it retrieves data without modifying state.
Register the MCPacer MCP server in PolicyLayer and add a rule for get_activities: 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 MCPacer. Nothing to install.
get_activities 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_activities 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_activities. 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_activities is provided by the MCPacer MCP server (wernerpe/mcpacer). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from MCPacer, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
