// FAQ

How many tools does the Openstudio MCP server have? +

The Openstudio MCP server exposes 146 tools across 5 categories: Read, Write, Destructive, Execute, Other.

How do I enforce policies on Openstudio tools? +

Route the Openstudio 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 Openstudio tools fall into? +

Openstudio tools are categorised as Read (64), Write (67), Destructive (8), Execute (6), Other (1). Each category has a recommended default policy.

Enforce policy on every Openstudio tool call.

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