List all physics interfaces defined in a model.
AI agents call physics_list to retrieve information from COMSOL MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and enumerates existing physics interface configurations from a COMSOL model. It performs no writes, deletions, code execution, or irreversible operations—it is purely informational. The blast radius of misuse is minimal, as listing model contents poses no risk of data loss, corruption, or unintended effects.
From the tool's definition Tool name 'physics_list' and description 'List all physics interfaces defined in a model' indicate a query/retrieval operation with no modification or side effects.
Attacks that exploit this kind of access
List all physics interfaces defined in a model. It is categorised as a Read tool in the COMSOL MCP Server MCP Server, which means it retrieves data without modifying state.
Register the COMSOL MCP Server MCP server in PolicyLayer and add a rule for physics_list: 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_list is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the physics_list 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_list. 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_list 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.
Every MCP server has a record like this.
