AI agents call find_proposal 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 performs a query operation to retrieve proposal records based on search criteria. It has no side effects—it does not create, modify, delete, or execute any external operations. The optional project filter is merely a query parameter. This is a straightforward read operation with minimal risk.
From the tool's definition Tool name is 'find_proposal' with description stating it 'Search for proposals by proposal number, title, or description.' The verb 'search' and 'find' indicate read-only retrieval operations with no modification, creation, or deletion of data.
Attacks that exploit this kind of access
Search for proposals by proposal number, title, or description. Can optionally filter by project. 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 find_proposal: 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.
find_proposal 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 find_proposal 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 find_proposal. 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.
find_proposal 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.
find_proposal is one line of Joe's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
