DuckDB is suitable for local analysis.\n\n\"mcp-server-duckdb\n\n## Overview\n\nThis server enables interaction with a DuckDB database through the Model Context Protocol, allowing for database operations like querying, table creation, and schema inspection.\n\n## Components\n\n### Resources\n\nCurrently, no custom resources are implemented.\n\n### Prompts\n\nCurrently, no custom prompts are implemented.\n\n### Tools\n\nThe server implements the following database interaction tool:\n\n- **query**: Execute any SQL query on the DuckDB database\n - **Input**: `query` (string) - Any valid DuckDB SQL statement\n - **Output**: Query results as text (or success message for operations like CREATE/INSERT)\n\n> [!NOTE]\n> The server provides a single unified `query` function rather than separate specialized functions, as modern LLMs can generate appropriate SQL for any database operation (SELECT, CREATE TABLE, JOIN, etc.) without requiring separate endpoints.\n\n> [!NOTE]\n> When the server is running in `readonly` mode, DuckDB's native readonly protection is enforced.\n> This ensures that the Language Model (LLM) cannot perform any write operations (CREATE, INSERT, UPDATE, DELETE), maintaining data integrity and preventing unintended changes.\n\n## Configuration\n\n### Required Parameters\n\n- **db-path** (string): Path to the DuckDB database file\n - The server will…","publisher":null,"homepage":"https://github.com/ktanaka101/mcp-server-duckdb","repository":"https://github.com/ktanaka101/mcp-server-duckdb/issues","version":"1.1.0","license":"The MIT License (MIT) Copyright (c) 2024 ktanaka101 Permissio…","protocols":["mcp"],"tags":["mcp"],"pricing":null,"endpoints":[{"url":"pypi:iflow-mcp_mcp-server-duckdb","type":"package_pypi","auth":null,"probeable":false},{"url":"pypi:mcp-server-duckdb","type":"package_pypi","auth":null,"probeable":false},{"url":"pypi:mseep-mcp-server-duckdb","type":"package_pypi","auth":null,"probeable":false},{"url":"pypi:orange-mcp-server-duckdb","type":"package_pypi","auth":null,"probeable":false}],"skills":null,"tools":null,"extra":null,"attribution":{"kind":"pypi","name":"pypi","license":"pypi","repoUrl":"pypi","summary":"pypi","version":"pypi","description":"pypi","homepageUrl":"pypi"}},"derived":{"capabilities":[{"slug":"data.database","name":"Databases","confidence":1,"provenance":"derived"},{"slug":"ai.prompting","name":"Prompt Management","confidence":0.791,"provenance":"derived"}],"categories":["ai","data"],"language":"en"},"observed":{"status":"unknown","statusReason":"Distributed as a package to run locally; no network endpoint to check.","lastOkAt":null,"lastProbedAt":null,"statusComputedAt":null,"reliability30d":null,"latestObservations":[],"tools":null,"package":{"name":"mcp-server-duckdb","registry":"pypi","observedAt":"2026-09-10T09:26:40.257Z","publishedAt":"2025-05-05T11:00:15.443777Z","latestVersion":"1.1.0"}},"verification":{"claimed":false,"claimedAt":null,"proofs":[]},"provenance":{"sources":[{"source":"pypi","key":"mcp-server-duckdb","url":"https://pypi.org/project/mcp-server-duckdb/","firstSeenAt":"2026-09-10T03:20:22.468Z","fetchedAt":"2026-09-10T03:20:22.468Z","normalizedAt":"2026-09-10T03:20:22.468Z"},{"source":"pypi","key":"orange-mcp-server-duckdb","url":"https://pypi.org/project/orange-mcp-server-duckdb/","firstSeenAt":"2026-09-10T09:24:48.917Z","fetchedAt":"2026-09-10T09:24:48.917Z","normalizedAt":"2026-09-10T09:24:48.917Z"},{"source":"pypi","key":"iflow-mcp_mcp-server-duckdb","url":"https://pypi.org/project/iflow-mcp_mcp-server-duckdb/","firstSeenAt":"2026-09-09T20:23:43.863Z","fetchedAt":"2026-09-09T20:23:43.863Z","normalizedAt":"2026-09-09T20:23:43.863Z"},{"source":"pypi","key":"mseep-mcp-server-duckdb","url":"https://pypi.org/project/mseep-mcp-server-duckdb/","firstSeenAt":"2026-09-10T07:19:17.491Z","fetchedAt":"2026-09-10T07:19:17.491Z","normalizedAt":"2026-09-10T07:19:17.491Z"}]},"firstSeenAt":"2026-09-09T20:23:43.863Z","updatedAt":"2026-09-10T09:26:40.257Z"}
