MOST DANGEROUS TOOLS

High Risk

The most dangerous MCP OpenAPI Discovery tools

Execute · High call_endpoint This tool executes real HTTP requests against external APIs, potentially performing any operation (read, write, delete, financial) depending on the endpoint called.

1 of MCP OpenAPI Discovery's 8 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control MCP OpenAPI Discovery

PolicyLayer is an MCP gateway — it sits between your AI agents and MCP OpenAPI Discovery, and nothing reaches the server without passing your rules. These are the rules we recommend:

Cap read operations

{
  "detect_openapi": {
    "limits": [
      {
        "counter": "detect_openapi_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

Controls API costs and prevents retry loops from exhausting upstream rate limits.

Create a free account and register MCP OpenAPI Discovery — nothing to install.
Add these rules — paste them, or build them visually. Tune the limits to your setup.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about MCP OpenAPI Discovery

Is the MCP OpenAPI Discovery MCP server safe to use without restrictions? +

The MCP OpenAPI Discovery server is primarily read-only with 7 read tools. While it cannot modify data, an agent in a retry loop can make thousands of API calls per minute, exhausting rate limits and running up costs. Rate limiting is still recommended.

How many tools does the MCP OpenAPI Discovery MCP server expose? +

8 tools across 1 categories: Read. 7 are read-only. 1 can modify, create, or delete data.

How do I enforce a policy on MCP OpenAPI Discovery? +

Register the MCP OpenAPI Discovery MCP server in PolicyLayer, apply the suggested rules above (adjust the limits to your use case), and point your AI client at the PolicyLayer proxy URL instead of the server directly. Your agents keep the same tools; PolicyLayer evaluates every call against policy before it executes. Nothing to install, live in minutes.

Enforce policy on every MCP OpenAPI Discovery tool call.

Deterministic rules across all 8 MCP OpenAPI Discovery tools. Per-identity grants. Full audit log. Live in minutes. Nothing to install.
