RECOMMENDED RULE

The rule that runs extract_text safely

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

extract_text Allowed

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

  "tools": {
    "extract_text": {}
  }
}

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

The button opens the PolicyLayer dashboard: create your workspace, connect ContextForge MCP Gateway, apply this rule, and every extract_text call is checked against it from then on.
