exit_sketch · Solidworks MCP: Risk & Policy

WHAT IT DOES

What exit_sketch does on Solidworks

AI agents invoke exit_sketch to trigger actions in Solidworks. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why exit_sketch needs a policy

This tool exits sketch mode and triggers a 'rebuild' operation in SolidWorks, which re-evaluates and recomputes the model geometry. It is not a simple read, but an active operation that modifies the application state and triggers computation. While not destructive, it executes a state transition and rebuild process whose effects depend on the current model context.

Verdict

exit_sketch Rate-limited

exit_sketch stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches Solidworks, so you can run agents against it safely.

FAQ

Questions about exit_sketch

What does the exit_sketch tool do? +

Exit sketch edit mode and rebuild. It is categorised as a Execute tool in the Solidworks MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on exit_sketch? +

Register the Solidworks MCP server in PolicyLayer and add a rule for exit_sketch: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Solidworks. Nothing to install.

What risk level is exit_sketch? +

exit_sketch is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit exit_sketch? +

Yes. Add a rate_limit block to the exit_sketch rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block exit_sketch completely? +

Set action: deny in the PolicyLayer policy for exit_sketch. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides exit_sketch? +

exit_sketch is provided by the Solidworks MCP server (solidworks-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
