It emphasizes that database tool failures can stem from various distinct causes, such as connection issues or query syntax errors, which should not be lumped together. Instead, effective MCP errors should provide structured, specific explanations to ensure the system remains operable beyond the \"happy path\" of successful queries.", "body_md": "“Tool failed” is not an error message.\nIt is a debugging tax.\nWhen an AI agent queries a database through MCP, failures need to be structured enough for the agent to recover and specific enough for humans to audit.\nA database tool can fail because:\nThose should not all collapse into the same generic error.\nA useful MCP database error explains:\nLonger version: MCP tool errors for AI database agents\nThe happy path demos well.
