THE RISK

Low Risk

Why search_papers needs a policy

This tool retrieves and queries paper data from a database. It does not create, modify, delete, or execute any operations—it only returns matching results based on search criteria. This is a straightforward Read operation with minimal risk, as the worst outcome would be information disclosure of already-accessible paper metadata.

From the tool's definition Tool performs 'full-text search across all stored papers' with no modification, deletion, or execution capabilities mentioned. Searching and querying data is a read-only operation with no side effects.

POLICY

How to control search_papers

PolicyLayer is an MCP gateway — it sits between your AI agents and Paper Scout MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for search_papers:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "search_papers": {}
  }
}

search_papers is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register Paper Scout MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
