results_evaluate · COMSOL MCP Server MCP: Risk & Policy

WHAT IT DOES

What results_evaluate does on COMSOL MCP Server

AI agents invoke results_evaluate to trigger actions in COMSOL MCP Server. 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 results_evaluate needs a policy

In COMSOL, 'evaluate' typically means computing/running expressions or post-processing evaluations against simulation data, which constitutes executing a computation. Given the simulation automation context and sibling tools, this likely triggers computational evaluation rather than a simple read. However, the empty description significantly lowers confidence.

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

Verdict

results_evaluate Rate-limited

results_evaluate 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 COMSOL MCP Server, so you can run agents against it safely.

FAQ

Questions about results_evaluate

What does the results_evaluate tool do? +

results_evaluate. It is categorised as a Execute tool in the COMSOL MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on results_evaluate? +

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

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

Can I rate-limit results_evaluate? +

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

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

results_evaluate 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.
