Why server_info needs a policy

This tool queries and returns information about the server's configuration and capabilities. It has no side effects, does not modify data, does not execute commands, and does not access sensitive user data beyond basic server metadata. It is a straightforward informational read operation.

From the tool's definition Tool name 'server_info' and description 'Describe the MCP server, configured models, and main capabilities' indicate retrieval of metadata about the server itself with no data modification or external action.

POLICY

How to control server_info

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

policy.json

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

server_info 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 Instagram — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
