AI agents use remove_gear_from_activity to create or update resources in Garmin Connect — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Garmin Connect environment.
Removing a link between gear and an activity is a reversible write operation — the gear item still exists and can be re-linked. It modifies association data but does not permanently delete any records, so Write is the appropriate category rather than Destructive.

Documented attack patterns abuse exactly the kind of access remove_gear_from_activity gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Garmin Connect, and nothing reaches the server without passing your rules. This is the rule we recommend for remove_gear_from_activity:
{
"version": "1",
"default": "deny",
"tools": {
"remove_gear_from_activity": {
"limits": [
{
"counter": "remove_gear_from_activity_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}remove_gear_from_activity stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Unlink a gear item from an activity. It is categorised as a Write tool in the Garmin Connect MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Garmin Connect MCP server in PolicyLayer and add a rule for remove_gear_from_activity: 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 Connect. Nothing to install.
remove_gear_from_activity is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the remove_gear_from_activity 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 remove_gear_from_activity. 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.
remove_gear_from_activity is provided by the Garmin Connect MCP server (nicolasvegam/garmin-connect-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
