discover_tools
AI agents call discover_tools to retrieve information from MCP Git Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool appears designed to enumerate or list available tools on the server, which is a read-only introspection operation. Without executing code, modifying repositories, or deleting data, it falls under the Read category. Low confidence due to missing description; could potentially be benign tool discovery or exploratory functionality.
From the tool's definition Tool name 'discover_tools' indicates tool discovery/enumeration; empty description limits specificity, but naming convention suggests information retrieval of available server capabilities rather than data mutation or execution.
Attacks that exploit this kind of access
discover_tools. It is categorised as a Read tool in the MCP Git Server MCP Server, which means it retrieves data without modifying state.
Register the MCP Git Server MCP server in PolicyLayer and add a rule for discover_tools: 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 MCP Git Server. Nothing to install.
discover_tools 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 discover_tools 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 discover_tools. 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.
discover_tools is provided by the MCP Git Server MCP server (mementorc/mcp-git). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
