WHAT IT DOES

What docs_generate_openapi does on Plugin Hub

AI agents call docs_generate_openapi to retrieve information from Plugin Hub without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why docs_generate_openapi is rated Low

Even though docs_generate_openapi only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs docs_generate_openapi safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Plugin Hub, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For docs_generate_openapi, this is the rule to start with:

docs_generate_openapi Allowed

docs_generate_openapi is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

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

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Plugin Hub, apply this rule, and every docs_generate_openapi call is checked against it from then on.
