Get comments for a specific activity
AI agents call getActivityComments to retrieve information from Strava without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves existing comment data associated with a Strava activity. It performs a read-only operation that does not create, modify, delete, or execute any actions. Even in a Strava fitness context, retrieving public or user-owned comments poses minimal security risk compared to write, destructive, or execute operations.
From the tool's definition Tool name is 'getActivityComments' and description states 'Get comments for a specific activity' — this is a retrieval operation with no modification or side effects.
Documented attack patterns abuse exactly the kind of access getActivityComments gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Strava, and nothing reaches the server without passing your rules. This is the rule we recommend for getActivityComments:
{
"version": "1",
"default": "deny",
"tools": {
"getActivityComments": {}
}
}getActivityComments is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get comments for a specific activity. It is categorised as a Read tool in the Strava MCP Server, which means it retrieves data without modifying state.
Register the Strava MCP server in PolicyLayer and add a rule for getActivityComments: 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 Strava. Nothing to install.
getActivityComments 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 getActivityComments 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 getActivityComments. 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.
getActivityComments is provided by the Strava MCP server (kw510/strava-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Strava, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
