Best Database MCP Servers in 2026

DBHub by Bytebase is the best database MCP server in 2026: with 3,032 GitHub stars as of July 2026, it is the most-starred genuine database server in the Remote OpenClaw directory's 704-server Databases category, and it connects an AI agent to PostgreSQL, MySQL, MariaDB, SQL Server, and SQLite through one gateway. If you run a single engine, a dedicated server usually beats a gateway, which is why the seven picks below cover Postgres, MongoDB, Supabase, ClickHouse, Redis, and Neon individually, each ranked by GitHub stars with a verified install command.

How We Ranked the Best Database MCP Servers

Database MCP servers are Model Context Protocol servers that let an AI agent query and manage a database through natural language instead of hand-written SQL. This list ranks them by GitHub stars inside the Remote OpenClaw Databases category, verified against each repository on July 4, 2026, and picks one clear winner per engine so the list reads as a starter kit rather than a pile of near-duplicates.

One filtering note: the raw star leaderboard in the Databases category includes tools like knowledge-base scrapers and code-graph indexers that are not really databases. We removed those so every entry below is a server whose job is talking to an actual database engine. For a workflow-focused companion, see our database management MCP roundup.

The 8 Best Database MCP Servers in 2026

These eight servers cover universal SQL access, Postgres, MySQL, MongoDB, Supabase, ClickHouse, Redis, and Neon. Install commands were verified against each repository's README in July 2026.

1. DBHub - one server, five SQL engines

DBHub (3,032 stars) is a universal database gateway that exposes PostgreSQL, MySQL, MariaDB, SQL Server, and SQLite through a single MCP endpoint, so one install covers most stacks. You point it at a database with a standard connection string (DSN). Directory page: bytebase/dbhub.

claude mcp add dbhub -- npx -y @bytebase/dbhub@latest --transport stdio --dsn "postgres://user:pass@localhost:5432/dbname?sslmode=disable"

2. Postgres MCP Pro - deep PostgreSQL tuning

Postgres MCP Pro (2,965 stars) goes past schema browsing with index tuning that simulates hypothetical indexes via the hypopg extension, EXPLAIN plan review, and database health checks. Its access-mode flag lets you lock it to read-only for safer production use. Full walkthrough in our Postgres MCP server guide; directory page: crystaldba/postgres-mcp.

claude mcp add postgres -- uvx postgres-mcp --access-mode=unrestricted

3. MongoDB MCP Server - the official document-database pick

The official MongoDB MCP Server (1,064 stars) reads collections, runs aggregations, and manages Atlas clusters from chat, covering the biggest NoSQL engine that DBHub does not. Point it at a connection string with the MDB_MCP_CONNECTION_STRING environment variable. Directory page: mongodb-js/mongodb-mcp-server.

claude mcp add mongodb -- npx -y mongodb-mcp-server

4. Supabase MCP Server - Postgres plus platform APIs

Supabase MCP Server (827 stars) runs SQL with risk assessment, manages schema migrations with versioning, and calls the Supabase Management and Auth Admin APIs, all with built-in safety controls. It needs your project ref and database password set as environment variables. See our Supabase MCP guide; directory page: alexander-zuev/supabase-mcp-server.

5. ClickHouse MCP - analytics at column-store speed

The official ClickHouse MCP (810 stars) runs read-only analytical queries against ClickHouse and also ships chDB support for in-process OLAP, which suits agents that need to summarize large event tables. Directory page: ClickHouse/mcp-clickhouse.

claude mcp add clickhouse -- uvx mcp-clickhouse

6. Neon MCP - serverless Postgres over a remote endpoint

The official Neon MCP Server (612 stars) manages serverless Postgres projects, branches, and migrations, and it runs as a hosted remote server at https://mcp.neon.tech/mcp with OAuth, so there is nothing local to install and no API key to paste. Directory page: neondatabase/mcp-server-neon.

claude mcp add --transport http neon https://mcp.neon.tech/mcp

7. Redis MCP - keys, caches, and vectors

The official Redis MCP (539 stars) reads and writes strings, hashes, streams, and vector indexes, which is useful when your agent needs to inspect a cache or session store rather than a relational table. Directory page: redis/mcp-redis.

claude mcp add redis -- uvx --from redis-mcp-server@latest redis-mcp-server --url redis://localhost:6379/0

8. AWS Database Servers - DynamoDB, Aurora, and more

For managed AWS engines, the awslabs/mcp monorepo (9,377 stars across the whole project) ships dedicated servers for DynamoDB, Aurora, DocumentDB, and other data stores, each published to PyPI and run with your AWS credentials. Directory page: awslabs/mcp.

Comparison Table: Best Database MCP Servers at a Glance

The table below compares all eight picks on engine coverage, stars, and hosting model, with star counts current as of July 4, 2026.

How to Choose a Database MCP Server

Pick a universal gateway when your stack mixes engines, and a dedicated server when it does not. DBHub is the fastest way to give an agent read access across a mixed SQL environment, but a single-engine tool like Postgres MCP Pro exposes engine-specific superpowers, in this case index tuning and EXPLAIN analysis, that a generic gateway cannot.

Match the transport to your setup, too. Remote servers like Neon use OAuth and need no local process, which is convenient but routes queries through a vendor endpoint. Local servers keep the connection inside your machine but require you to manage the connection string and credentials yourself. For anything touching production, start read-only: Postgres MCP Pro, DBHub, and the AWS servers all support restricted or read-only modes.

Whichever you choose, add it through the standard MCP flow. Our Claude Code MCP servers guide covers scopes and environment variables, and the full cross-category ranking lives in Best MCP Servers in 2026.

Limitations and Tradeoffs

A database MCP server is only as safe as the credentials you give it. An agent with write access can drop tables or leak rows through prompt injection, so scope the connection to a read-only role and a single schema, and treat every server as untrusted code until you have reviewed it. Our guide on securing MCP server connections covers credential scoping and read-only modes in depth.

Stars measure popularity, not safety or freshness. The AWS monorepo's 9,377 stars belong to dozens of servers, not one, and a 500-star server updated last week can be a better bet than a 5,000-star project abandoned a year ago, which is why the table pairs stars with what each server actually connects to. When a count reflects a whole project rather than its MCP endpoint, we say so.
