一个用于SQL数据库的单二进制MCP服务器。将你的AI助手连接到MySQL/MariaDB、PostgreSQL或SQLite，且不依赖任何运行时。

网站文档发行

特色 ✨

• 多数据库 — MySQL/MariaDB、PostgreSQL 和 SQLite 从一个二进制文件中实现
• MCP 工具 — 模式发现（listDatabases、listTables、listViews、listTriggers、listFunctions、listProcedures、listMaterializedViews）、数据访问（readQuery、writeQuery）、DDL（createDatabase、dropDatabase、dropTable）和 explainQuery。只读模式隐藏写入工具（writeQuery、createDatabase、dropDatabase、dropTable）。详见 MCP 工具以了解每个后端的可用性。
• 单一二进制 — ~7 MB，无需 Python/Node/Docker
• 多重传输 — stdio（针对 Claude 桌面、光标）和 HTTP（用于远程/多客户端）
• 两层配置 — CLI 标志环境变量>，每个后端有合理的默认值
• SSH 隧道 — 通过带有嵌入式客户端的 SSH 堡垒访问 MySQL/MariaDB/PostgreSQL：密码或密钥认证、known_hosts 验证，自动重新连接

Features ✨

• Multi-database — MySQL/MariaDB, PostgreSQL, and SQLite from one binary
• MCP tools — schema discovery (listDatabases, listTables, listViews, listTriggers, listFunctions, listProcedures, listMaterializedViews), data access (readQuery, writeQuery), DDL (createDatabase, dropDatabase, dropTable), and explainQuery. Read-only mode hides the write tools (writeQuery, createDatabase, dropDatabase, dropTable). See MCP Tools for per-backend availability.
• Single binary — ~7 MB, no Python/Node/Docker needed
• Multiple transports — stdio (for Claude Desktop, Cursor) and HTTP (for remote/multi-client)
• Layered config — DBMCP_* environment variables, an env file, and an optional YAML config file with ${} interpolation, with sensible defaults per backend
• SSH tunnel — reach MySQL/MariaDB/PostgreSQL through an SSH bastion with an embedded client: password or key auth, known_hosts verification, automatic reconnect

Install 📦

macOS, Linux, WSL:

curl -fsSL https://dbmcp.haymon.ai/install.sh | bash

Windows PowerShell:

irm https://dbmcp.haymon.ai/install.ps1 | iex

Windows CMD:

curl -fsSL https://dbmcp.haymon.ai/install.cmd -o install.cmd && install.cmd && del install.cmd

See the installation docs for Docker, Cargo, and other methods.

Quick Start 🚀

Using .mcp.json (recommended)

Add a .mcp.json file to your project root. MCP clients read this file and configure the server automatically.

Stdio transport — the client starts and manages the server process:

{
  "mcpServers": {
    "dbmcp": {
      "command": "dbmcp",
      "env": {
        "DBMCP_DB_BACKEND": "mysql",
        "DBMCP_DB_HOST": "127.0.0.1",
        "DBMCP_DB_PORT": "3306",
        "DBMCP_DB_USER": "root",
        "DBMCP_DB_PASSWORD": "secret",
        "DBMCP_DB_NAME": "mydb"
      }
    }
  }
}

HTTP transport — you start the server yourself, the client connects to it:

# Start the server first
