Get activities from the past X days.
AI agents call get_recent_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.
The tool retrieves historical activity data from Strava without modifying, deleting, or executing any operations. It poses minimal security risk as it only queries existing data that the authenticated user has access to. The blast radius is low—misuse would only expose data the user has already authorized access to.
From the tool's definition Tool name 'get_recent_activities' and description 'Get activities from the past X days' indicate a retrieval operation with no side effects.
Documented attack patterns abuse exactly the kind of access get_recent_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_recent_activities:
{
"version": "1",
"default": "deny",
"tools": {
"get_recent_activities": {}
}
}get_recent_activities is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get activities from the past X days. 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_recent_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_recent_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_recent_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_recent_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_recent_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.
