What search does on Go
AI agents call search to retrieve information from Go without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why search is rated Low
This is a read-only operation that retrieves package information from the npm registry. Search operations do not modify, delete, or execute any code—they simply return matching package metadata in response to a user query. The blast radius of misuse is minimal since no data is created, modified, deleted, or executed.
From the tool's definition Tool searches the npm registry for packages matching a query; this is a query operation with no side effects.
Attacks that exploit this kind of access
The rule that runs search safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Go, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For search, this is the rule to start with:
search is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Go, apply this rule, and every search call is checked against it from then on.
Questions about search
Searches the npm registry for packages matching a query. It is categorised as a Read tool in the Go MCP Server, which means it retrieves data without modifying state.
Register the Go MCP server in PolicyLayer and add a rule for search: 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 Go. Nothing to install.
search 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 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. 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 is provided by the Go MCP server (Dave-London/Pare). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
