Get a list of available physics interfaces organized by category.
AI agents call physics_get_available 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 retrieves and lists available physics interfaces without modifying, executing, deleting, or financially impacting any data or systems. It is purely informational and read-only in nature, making it a Read category tool with low severity.
From the tool's definition Tool name is 'physics_get_available' and description states it 'Get a list of available physics interfaces organized by category.' This is a simple query/retrieval operation with no side effects.
Attacks that exploit this kind of access
Get a list of available physics interfaces organized by category. 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 physics_get_available: 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.
physics_get_available 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_available 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_available. 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_available 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.
