WHAT IT DOES

What physics_boundary_selection does on COMSOL MCP Server

AI agents use physics_boundary_selection 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 physics_boundary_selection needs a policy

Based on the tool name, this likely modifies or assigns boundary condition selections within a COMSOL physics model, which is a write/configuration operation. However, the empty description significantly lowers confidence. It could also be a Read operation if it merely queries existing selections.

From the tool's definition Tool name 'physics_boundary_selection' suggests selecting/assigning boundary conditions in a physics simulation context; description is empty and uninformative.

Verdict

physics_boundary_selection Rate-limited

physics_boundary_selection 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 physics_boundary_selection

What does the physics_boundary_selection tool do? +

physics_boundary_selection. 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 physics_boundary_selection? +

Register the COMSOL MCP Server MCP server in PolicyLayer and add a rule for physics_boundary_selection: 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 physics_boundary_selection? +

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

Can I rate-limit physics_boundary_selection? +

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

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

physics_boundary_selection 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.
