MOST DANGEROUS TOOLS

Critical Risk

The most dangerous COMSOL MCP Server tools

Destructive · High model_remove Removing a model from memory destroys the in-memory representation of a simulation model, which is an irreversible action within the current session. Destructive · High physics_remove 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 s Destructive · High comsol_disconnect Clearing all models from memory is an irreversible destructive action — any unsaved simulation state, model configurations, and in-memory data are permanently lost upon disconnection. Execute · Medium study_cancel Cancelling a running simulation/solve operation is an action that terminates an ongoing execution process.

47 of COMSOL MCP Server's 78 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control COMSOL MCP Server

PolicyLayer is an MCP gateway — it sits between your AI agents and COMSOL MCP Server, and nothing reaches the server without passing your rules. These are the rules we recommend:

Deny destructive operations

{
  "comsol_disconnect": {
    "deny_if": [
      {
        "conditions": [],
        "on_deny": "Blocked by default. Requires approval."
      }
    ]
  }
}

Destructive tools should never be available to autonomous agents without human approval.

Rate limit write operations

{
  "geometry_add_block": {
    "limits": [
      {
        "counter": "geometry_add_block_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "comsol_status": {
    "limits": [
      {
        "counter": "comsol_status_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

Controls API costs and prevents retry loops from exhausting upstream rate limits.

Add these rules — paste them, or build them visually. Tune the limits to your setup.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about COMSOL MCP Server

Can an AI agent delete data through the COMSOL MCP Server MCP server? +

Yes. The COMSOL MCP Server server exposes 3 destructive tools including comsol_disconnect, model_remove, physics_remove. These permanently remove resources with no undo. PolicyLayer blocks destructive tools by default so they never reach the upstream server.

How do I prevent bulk modifications through COMSOL MCP Server? +

The COMSOL MCP Server server has 33 write tools including geometry_add_block, geometry_add_circle, geometry_add_cylinder. Set a rate limit in your policy -- for example, 10 calls per hour prevents an agent from making more than 10 modifications per hour. PolicyLayer enforces this at the gateway, before calls reach COMSOL MCP Server.

How many tools does the COMSOL MCP Server MCP server expose? +

78 tools across 5 categories: Destructive, Execute, Financial, Read, Write. 31 are read-only. 47 can modify, create, or delete data.

How do I enforce a policy on COMSOL MCP Server? +

Register the COMSOL MCP Server MCP server in PolicyLayer, apply the suggested rules above (adjust the limits to your use case), and point your AI client at the PolicyLayer proxy URL instead of the server directly. Your agents keep the same tools; PolicyLayer evaluates every call against policy before it executes. Nothing to install, live in minutes.

Enforce policy on every COMSOL MCP Server tool call.

Deterministic rules across all 78 COMSOL MCP Server tools. Per-identity grants. Full audit log. Live in minutes. Nothing to install.
