Discover comprehensive project data by searching for a project and retrieving all related information including project details, financials (estimates, job balances, cost variance), schedules, and action items - all in one unified JSON response
AI agents call discover to retrieve information from JoeMCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool searches and retrieves existing project data including details, financials, schedules, and action items. While it accesses sensitive financial information (estimates, job balances, cost variance), the operation itself is read-only with no side effects—it does not create, modify, delete, or execute anything.
From the tool's definition The tool description states it 'searching for a project and retrieving all related information' and returns 'all in one unified JSON response'.
Attacks that exploit this kind of access
Discover comprehensive project data by searching for a project and retrieving all related information including project details, financials (estimates, job balances, cost variance), schedules, and action items - all in one unified JSON response. It is categorised as a Read tool in the JoeMCP MCP Server, which means it retrieves data without modifying state.
Register the Joe MCP server in PolicyLayer and add a rule for 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 JoeMCP. Nothing to install.
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 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 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.
discover is provided by the Joe MCP server (lumberjack-so/joemcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
