Search device-specific reference documentation and capabilities
AI agents call search_device_reference to retrieve information from Garmin Documentation 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 and queries static documentation about Garmin devices. It has no side effects, does not modify any data, and serves only to provide information to the user. It is a read-only operation typical of documentation lookup utilities.
From the tool's definition Tool is named 'search_device_reference' and described as 'Search device-specific reference documentation and capabilities'. The verb 'search' combined with 'reference documentation' and 'capabilities' indicates data retrieval only.
Documented attack patterns abuse exactly the kind of access search_device_reference gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Garmin Documentation MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for search_device_reference:
{
"version": "1",
"default": "deny",
"tools": {
"search_device_reference": {}
}
}search_device_reference is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Search device-specific reference documentation and capabilities. It is categorised as a Read tool in the Garmin Documentation MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Garmin Documentation MCP Server MCP server in PolicyLayer and add a rule for search_device_reference: 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 Documentation MCP Server. Nothing to install.
search_device_reference 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 search_device_reference 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 search_device_reference. 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.
search_device_reference is provided by the Garmin Documentation MCP Server MCP server (ztuskes/garmin-documentation-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Garmin Documentation MCP Server, 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.
