# run_query Execute a query against the data warehouse Agent View of the PolicyLayer registry record for `run_query`. HTML page: https://policylayer.com/tools/coder-rl-claude-mcpserver-dev1/run-query ## Facts - Tool: `run_query` - Server: Claude MCP Server Ecosystem (`coder-rl/claude_mcpserver_dev1`) — https://policylayer.com/tools/coder-rl-claude-mcpserver-dev1.md - Homepage: https://github.com/Coder-RL/Claude_MCPServer_Dev1 - Risk category: Execute (High risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Rate-limited ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "run_query", "arguments": {} } } ``` ## Why run_query is rated High This tool permits execution of queries against a data warehouse, which can have significant side effects depending on the query content (SELECT, UPDATE, DELETE, DROP, etc.). While the description does not explicitly state that destructive operations are allowed, the broad 'execute a query' capability suggests the tool accepts arbitrary SQL. From the tool's own definition: "Tool name 'run_query' combined with description 'Execute a query against the data warehouse' indicates execution of arbitrary queries against a database system. The verb 'Execute' in the description is explicit." ## Use case AI agents invoke run_query to trigger actions in Claude MCP Server Ecosystem. 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. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**.
