"DuckDB" matching MCP servers:

Enables running read-only SQL queries and exploring DuckDB databases through MCP tools like listing tables, describing schemas, and fetching paginated data.

Enables querying Eurostat data using natural language, powered by DuckDB for optimized performance.

Provides read-only SQL analytics on local CSV, Parquet, and JSON datasets using DuckDB, with pagination, security guardrails, and health monitoring.

Universal database MCP server connecting to MySQL, PostgreSQL, SQLite, DuckDB and etc.

Natural language to SQL engine with multi-connector support (PostgreSQL, MySQL, Snowflake, BigQuery, DuckDB), document QA, semantic caching, and self-hosted MCP server.

Zero-config data quality monitoring as MCP tools. Profiles a warehouse (Postgres, BigQuery, Snowflake, MySQL, DuckDB), detects anomalies, and gates CI — read-only with the connection resolved server-side, never via the model.

MCP server for Eurostat statistics, enabling seamless search, query, and analysis of over 8,900 EU datasets with support for SDMX, DuckDB SQL, NUTS regional filtering, and CSV export.

Persistent, searchable per-project memory for Claude Code using DuckDB and vector search, with rule enforcement and a management UI.

Enables LLMs to perform analytical SQL queries on PostgreSQL/MySQL databases via DuckDB, with tools for querying, aggregation, and materialized views.

High-speed Scientific Literature Semantic Compiler & FastMCP Server Powered by arXiv, OpenAlex, DuckDB HTTP range queries, and TypeSafe Jev System One.

Enables MCP clients to record, browse, read, aggregate, and delete time-series SCADA values addressed by UNS id through a broker-mediated history slot, with per-id broker capability checks and auditing. Backends are pluggable (in-memory today, with SQLite, DuckDB, and MySQL planned) behind a single store contract that a conformance suite validates.

Provides geospatial data intelligence tools for inspecting, querying, and converting geospatial data using DuckDB Spatial.

Enables Claude to ask questions about your fleet data via the Geotab ACE AI service, with support for multi-account authentication, async queries, and DuckDB caching for large datasets.

Provides read-only SQL query access to Postgres and DuckDB databases via MCP tools, with extensive security hardening for public endpoints.

Enables read-only access to explicitly approved local and remote filesystems, including inspecting Git repositories and querying SQLite and DuckDB databases, with root administration kept separate from MCP.

A drop-in replacement for mcp-memory-duckdb with full concurrent access support using Redis Stack. Enables persistent knowledge graph storage with full-text search and multi-session concurrent access.

Enables querying ecommerce data (customers, products, orders, reviews) using natural language via Cortex Analyst and Cortex Search, with SQL execution capability, all exposed as MCP tools.
