Scan this project and auto-discover which MCP servers would be useful.
AI agents call percept_discover to retrieve information from Perceptdot without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs project scanning and discovery to identify useful MCP servers. It retrieves and queries project metadata to recommend servers, which is fundamentally a read operation with no side effects. There is no creation, modification, deletion, code execution, or financial impact. The low severity reflects minimal risk even if an agent misuses it — scanning a project causes no harm.
From the tool's definition Tool description states 'Scan this project and auto-discover which MCP servers would be useful' — this is a discovery/scan operation that retrieves information about the project and available MCP servers without modifying anything.
Attacks that exploit this kind of access
Scan this project and auto-discover which MCP servers would be useful. It is categorised as a Read tool in the Perceptdot MCP Server, which means it retrieves data without modifying state.
Register the Perceptdot MCP server in PolicyLayer and add a rule for percept_discover: 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 Perceptdot. Nothing to install.
percept_discover 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 percept_discover 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 percept_discover. 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.
percept_discover is provided by the Perceptdot MCP server (perceptdot/percept). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
