List available Perceptron models and their capabilities.
AI agents call list_models to retrieve information from Perceptron Vision 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 operation—it retrieves and displays information about available models and their capabilities without modifying, deleting, or executing any operations. There is no data mutation, code execution, or irreversible action involved. The blast radius of misuse is negligible as an agent can only observe what models exist and their properties.
From the tool's definition Tool name 'list_models' and description 'List available Perceptron models and their capabilities' indicate a simple information retrieval operation that queries and returns metadata about available models with no side effects.
Attacks that exploit this kind of access
List available Perceptron models and their capabilities. It is categorised as a Read tool in the Perceptron Vision MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Perceptron Vision MCP Server MCP server in PolicyLayer and add a rule for list_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 Perceptron Vision MCP Server. Nothing to install.
list_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_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_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_models is provided by the Perceptron Vision MCP Server MCP server (perceptron-ai-inc/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
