param_list
AI agents call param_list 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.
The tool appears to list parameters in a COMSOL simulation context, which is a read-only retrieval operation. It queries existing parameter data without modifying, deleting, or executing code. The lack of description lowers confidence slightly, but the naming convention and server context provide reasonable evidence of a Read category tool.
From the tool's definition Tool name 'param_list' combined with server context focused on flexible pressure sensor simulation. The naming pattern aligns with list/query operations (compare to 'datasets_list', 'docs_list' on the same server).
Attacks that exploit this kind of access
param_list. 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 param_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 Flex Sensor Agent. Nothing to install.
param_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 param_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 param_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.
param_list 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.
