Process a natural language query and return schema information to construct a structured AllianceMine query. This tool returns the AllianceMine schema so you can convert the user
AI agents call mine_natural_query to retrieve information from AGR MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns schema metadata to help construct structured queries. It does not execute queries, modify data, delete records, run code, or trigger external state changes. The return of schema information is a pure read operation with no blast radius if misused by an agent.
From the tool's definition Tool description states it 'Process[es] a natural language query and return[s] schema information' — this is a retrieval operation that returns metadata about the AllianceMine schema with no side effects.

Process a natural language query and return schema information to construct a structured AllianceMine query. This tool returns the AllianceMine schema so you can convert the user. It is categorised as a Read tool in the AGR MCP Server MCP Server, which means it retrieves data without modifying state.
Register the AGR MCP Server MCP server in PolicyLayer and add a rule for mine_natural_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.
mine_natural_query 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 mine_natural_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.
Set action: deny in the PolicyLayer policy for mine_natural_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.
mine_natural_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.
