physics_get_guide
AI agents call physics_get_guide 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.
The 'get' verb indicates a retrieval operation without side effects. Despite the empty description, the naming convention and context from sibling tools (docs_get, datasets_list) strongly suggest this retrieves reference material or guidance about physics in COMSOL, which would be a non-destructive read operation. Severity is low as it merely provides information with no execution or modification capability.
From the tool's definition Tool name 'physics_get_guide' with 'get' verb suggests data retrieval. Description is empty, limiting certainty. Sibling tools like 'docs_get' and 'datasets_list' are clearly Read operations, suggesting this follows the same pattern.
Attacks that exploit this kind of access
physics_get_guide. 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_get_guide: 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_get_guide 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_get_guide 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_get_guide. 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_get_guide 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.
