Return supported base/target models and directory layout.
AI agents call list_available_models to retrieve information from SensorMCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and lists information about available models and system directory structure. It performs a read-only query with no capability to modify, delete, or execute operations. The blast radius of misuse is minimal—an attacker could only enumerate system capabilities and structure, which does not compromise data integrity or enable further attacks directly.
From the tool's definition Tool name 'list_available_models' and description 'Return supported base/target models and directory layout' indicate a retrieval/query operation with no modifications or side effects.
Attacks that exploit this kind of access
Return supported base/target models and directory layout. It is categorised as a Read tool in the SensorMCP Server MCP Server, which means it retrieves data without modifying state.
Register the SensorMCP Server MCP server in PolicyLayer and add a rule for list_available_models: 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 SensorMCP Server. Nothing to install.
list_available_models 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 list_available_models 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 list_available_models. 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.
list_available_models is provided by the SensorMCP Server MCP server (sensormcp/sensor-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
list_available_models is one line of SensorMCP Server's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
