geometry_add_cylinder · COMSOL MCP Server MCP: Risk & Policy

WHAT IT DOES

What geometry_add_cylinder does on COMSOL MCP Server

AI agents use geometry_add_cylinder to create or update resources in COMSOL MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your COMSOL MCP Server environment.

WHY IT NEEDS A POLICY

Why geometry_add_cylinder needs a policy

Based on naming convention consistent with sibling tools like 'geometry_add_block' and 'geometry_add_circle', this tool likely adds a cylinder geometry feature to a COMSOL simulation model — a reversible write operation. Empty description reduces confidence; no evidence of destructive or financial impact.

From the tool's definition Tool name 'geometry_add_cylinder' on a COMSOL Multiphysics simulation server; description is empty.

Verdict

geometry_add_cylinder Rate-limited

geometry_add_cylinder stays usable, but capped — an agent stuck in a loop can't make hundreds of changes 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 COMSOL MCP Server, so you can run agents against it safely.

FAQ

Questions about geometry_add_cylinder

What does the geometry_add_cylinder tool do? +

geometry_add_cylinder. It is categorised as a Write tool in the COMSOL MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on geometry_add_cylinder? +

Register the COMSOL MCP Server MCP server in PolicyLayer and add a rule for geometry_add_cylinder: 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 COMSOL MCP Server. Nothing to install.

What risk level is geometry_add_cylinder? +

geometry_add_cylinder is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit geometry_add_cylinder? +

Yes. Add a rate_limit block to the geometry_add_cylinder 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 geometry_add_cylinder completely? +

Set action: deny in the PolicyLayer policy for geometry_add_cylinder. 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 geometry_add_cylinder? +

geometry_add_cylinder is provided by the COMSOL MCP Server MCP server (zhangyoupeng1996/codex_mcp_comsol). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
