Remove a physics interface from the model.
AI agents call physics_remove to permanently remove resources in COMSOL MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Removing a physics interface from a COMSOL simulation model is a destructive action that cannot be trivially undone—it permanently deletes the configuration and any associated parameters, boundary conditions, or solver settings tied to that interface. While not data exfiltration or financial in nature, this action eliminates work artifacts irreversibly, making it Destructive rather than Write.
From the tool's definition Tool name is 'physics_remove' and description states it will 'Remove a physics interface from the model.' The verb 'remove' in the context of modifying simulation models indicates irreversible deletion of a configured physics interface.
Attacks that exploit this kind of access
Remove a physics interface from the model. It is categorised as a Destructive tool in the COMSOL MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the COMSOL MCP Server MCP server in PolicyLayer and add a rule for physics_remove: 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.
physics_remove is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the physics_remove 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.
Set action: deny in the PolicyLayer policy for physics_remove. 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.
physics_remove 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.
