List all components in a model.
AI agents call model_list_components to retrieve information from Flex Sensor Agent without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs data retrieval only—it queries the state of a COMSOL model to enumerate its components. There are no side effects, no code execution, no data modification, and no destructive operations. The action is purely informational and safe for an AI agent to invoke.
From the tool's definition Tool name 'model_list_components' and description 'List all components in a model' indicate a read-only query operation that retrieves and enumerates existing model data without modification or execution.
Attacks that exploit this kind of access
List all components in a model. It is categorised as a Read tool in the Flex Sensor Agent MCP Server, which means it retrieves data without modifying state.
Register the Flex Sensor Agent MCP server in PolicyLayer and add a rule for model_list_components: 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 Flex Sensor Agent. Nothing to install.
model_list_components 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 model_list_components 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 model_list_components. 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.
model_list_components is provided by the Flex Sensor Agent MCP server (tonghui666/flex-sensor-agent-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
