// FAQ

How many tools does the CodeRAG MCP server have? +

The CodeRAG MCP server exposes 38 tools across 3 categories: Read, Write, Destructive.

How do I enforce policies on CodeRAG tools? +

Route the CodeRAG server through the PolicyLayer gateway. Define allow, deny, or approval rules per tool in the dashboard; they are enforced on every call before it reaches the server.

What risk categories do CodeRAG tools fall into? +

CodeRAG tools are categorised as Read (27), Write (8), Destructive (3). Each category has a recommended default policy.

Enforce policy on every CodeRAG tool call.

Start from CodeRAG, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
