WHAT IT DOES

What get_provider_apis does on OpenAPI Directory MCP Server

AI agents call get_provider_apis to retrieve information from OpenAPI Directory MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

THE RISK

Low Risk

Why get_provider_apis needs a policy

This tool queries and retrieves metadata about available APIs from the OpenAPI Directory database. It does not modify, delete, execute, or perform financial operations. The operation is non-destructive, requires no external execution, and simply returns information already in the catalogue.

From the tool's definition Tool name 'get_provider_apis' and description 'List all APIs for a specific provider' indicate a retrieval/query operation with no side effects. The verb 'List' is explicitly read-only.

POLICY

How to control get_provider_apis

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

policy.json

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

get_provider_apis 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 OpenAPI Directory 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.
