List all export nodes defined in a model.
AI agents call results_exports_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 performs a read-only query of existing export node definitions. It has no side effects, does not execute simulations, does not modify model state, and does not access external systems. It is purely informational retrieval of model metadata.
From the tool's definition Tool name contains 'list' and description states 'List all export nodes defined in a model' — a query operation that retrieves metadata without modifying or executing anything.
Attacks that exploit this kind of access
List all export nodes 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 results_exports_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.
results_exports_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 results_exports_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 results_exports_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.
results_exports_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.
