param_description
AI agents call param_description 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.
Based on the tool name alone, 'param_description' likely retrieves or returns descriptive information about a parameter in the COMSOL simulation context, suggesting a Read operation. However, the empty description significantly lowers confidence. Given the naming convention of sibling tools (docs_get, datasets_list, etc.), this fits a Read pattern.
From the tool's definition Tool name is 'param_description'; description is empty and uninformative.
Attacks that exploit this kind of access
param_description. 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 param_description: 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.
param_description 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 param_description 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 param_description. 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.
param_description 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.
