mine_query · AGR MCP Server MCP: Risk & Policy

WHAT IT DOES

What mine_query does on AGR MCP Server

AI agents invoke mine_query to trigger actions in AGR MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why mine_query needs a policy

This tool executes raw, user-supplied PathQuery XML against the AllianceMine InterMine database. While InterMine PathQuery is primarily a read/query interface, allowing arbitrary query execution opens the door to complex or resource-intensive queries (denial of service), potential data exfiltration beyond intended scope, and depending on server configuration, possible write or destructive operations.

From the tool's definition "Run a raw PathQuery XML query against AllianceMine" — executes arbitrary user-supplied XML queries against the database backend

Verdict

mine_query Rate-limited

mine_query stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about mine_query

What does the mine_query tool do? +

Run a raw PathQuery XML query against AllianceMine. For power users who know InterMine PathQuery syntax. It is categorised as a Execute tool in the AGR MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on mine_query? +

Register the AGR MCP Server MCP server in PolicyLayer and add a rule for mine_query: 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 AGR MCP Server. Nothing to install.

What risk level is mine_query? +

mine_query is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit mine_query? +

Yes. Add a rate_limit block to the mine_query 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.

How do I block mine_query completely? +

Set action: deny in the PolicyLayer policy for mine_query. 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.

What MCP server provides mine_query? +

mine_query is provided by the AGR MCP Server MCP server (nuin/agr-mcp-server-js). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
