DBX MCP Server
MCP server for DBX — lets AI agents (Claude Code, Cursor, etc.) query your databases using connections already configured in DBX.
中文 | English
Features
- Zero config — Automatically reads your DBX connections (including passwords from system keyring)
- 8 tools — List/add/remove connections, list tables, describe table, get schema context, execute SQL, open table in DBX UI
- Connection pooling — Reuses database connections across queries
- Direct execution — PostgreSQL, MySQL, SQLite, and compatible databases (Doris, StarRocks, etc.) can run without opening DBX
- Read-only by default — SQL execution blocks write and dangerous statements unless explicitly enabled
- DBX UI integration — Open tables directly in the DBX desktop app from your AI agent
Quick Start
1. Install
npm install -g @dbx-app/mcp-serverOr run directly:
npx @dbx-app/mcp-server2. Configure Claude Code
Add to your project's .mcp.json:
{
"mcpServers": {
"dbx": {
"command": "dbx-mcp-server"
}
}
}Or for development (from source):
{
"mcpServers": {
"dbx": {
"command": "npx",
"args": ["tsx", "packages/mcp-server/src/index.ts"],
"cwd": "/path/to/dbx"
}
}
}3. Use
In Claude Code, just ask:
- "List my database connections"
- "Show the tables in my local-pg connection"
- "Describe the users table"
- "Query the average salary from employees"
- "Open the orders table in DBX"
CLI
For terminal, script, and Codex workflows, install the dedicated CLI package:
npm install -g @dbx-app/cli
dbx connections list --json
dbx query local "select 1" --jsonSee the DBX CLI README for command details.
Tools
| Tool | Description |
|---|---|
| dbx_list_connections | List all database connections configured in DBX |
| dbx_add_connection | Add a new database connection |
| dbx_remove_connection | Remove a database connection |
| dbx_list_tables | List tables and views for a connection |
| dbx_describe_table | Get column definitions for a table |
| dbx_get_schema_context | Get compact table and column context for writing SQL |
| dbx_execute_query | Execute a SQL query (max 100 rows) |
| dbx_open_table | Open a table in DBX desktop app UI |
SQL Safety
dbx_execute_query is read-only by default. To allow write statements such as INSERT or UPDATE, set:
DBX_MCP_ALLOW_WRITES=1Dangerous statements such as DROP, TRUNCATE, and ALTER remain blocked unless you also set:
DBX_MCP_ALLOW_DANGEROUS_SQL=1How It Works
AI Agent → MCP Server → Database
↓
DBX SQLite database (dbx.db)The MCP server reads your database connections from DBX's SQLite database:
- macOS:
~/Library/Application Support/com.dbx.app/dbx.db - Linux:
~/.config/com.dbx.app/dbx.db - Windows:
%APPDATA%\com.dbx.app\dbx.db
DBX UI Integration
The dbx_open_table tool communicates with the running DBX app to open tables directly in the UI. This requires DBX to be running. If DBX is not running, the tool will return an error message.
PostgreSQL, MySQL, SQLite, Doris, StarRocks, and Redshift queries run directly from the MCP server. Other database types still use the DBX desktop bridge for query, table, and column operations unless DBX_WEB_URL is configured.
Requirements
- DBX installed with at least one connection configured
- Node.js 18+

中文说明
DBX 的 MCP Server,让 AI 编程助手(Claude Code、Cursor 等)直接使用 DBX 中已配置的数据库连接查询数据。
特性
- 零配置 — 自动读取 DBX 的连接配置
- 8 个工具 — 列出/添加/删除连接、列出表、查看表结构、获取 Schema 上下文、执行 SQL、在 DBX 中打开表
- 连接池 — 跨查询复用数据库连接
- 直接执行 — PostgreSQL、MySQL、SQLite 及兼容数据库(Doris、StarRocks 等)无需打开 DBX 即可查询
- 默认只读 — SQL 执行默认拦截写操作和危险语句
- DBX UI 联动 — 从 AI 助手直接在 DBX 桌面端打开表
快速开始
1. 安装
npm install -g @dbx-app/mcp-server或直接运行:
npx @dbx-app/mcp-server2. 配置 Claude Code
在项目的 .mcp.json 中添加:
{
"mcpServers": {
"dbx": {
"command": "dbx-mcp-server"
}
}
}3. 使用
在 Claude Code 中直接说:
- "列出我的数据库连接"
- "查看 local-pg 上有哪些表"
- "查看 users 表的结构"
- "查询最近 7 天的订单数量"
- "打开 orders 表"
CLI
终端、脚本和 Codex 工作流请安装独立 CLI 包:
npm install -g @dbx-app/cli
dbx connections list --json
dbx query local "select 1" --json命令详情见 DBX CLI README。
工具列表
| 工具 | 说明 |
|---|---|
| dbx_list_connections | 列出 DBX 中所有已配置的数据库连接 |
| dbx_add_connection | 添加新的数据库连接 |
| dbx_remove_connection | 删除数据库连接 |
| dbx_list_tables | 列出指定连接的表和视图 |
| dbx_describe_table | 获取表的列定义 |
| dbx_get_schema_context | 获取适合 AI 写 SQL 的紧凑表结构上下文 |
| dbx_execute_query | 执行 SQL 查询(最多返回 100 行) |
| dbx_open_table | 在 DBX 桌面端打开指定表 |
SQL 安全
dbx_execute_query 默认只读。若要允许 INSERT、UPDATE 等写操作,设置:
DBX_MCP_ALLOW_WRITES=1DROP、TRUNCATE、ALTER 等危险语句仍会被拦截,除非额外设置:
DBX_MCP_ALLOW_DANGEROUS_SQL=1工作原理
MCP Server 从 DBX 的 SQLite 数据库读取连接信息:
- macOS:
~/Library/Application Support/com.dbx.app/dbx.db - Linux:
~/.config/com.dbx.app/dbx.db - Windows:
%APPDATA%\com.dbx.app\dbx.db
DBX UI 联动
dbx_open_table 工具通过本地 HTTP 接口与运行中的 DBX 应用通信,直接在 UI 中打开表。需要 DBX 正在运行。
PostgreSQL、MySQL、SQLite、Doris、StarRocks、Redshift 查询可由 MCP Server 直接执行。其他数据库类型的查询、表列表、字段读取仍会走 DBX 桌面端 bridge,除非配置了 DBX_WEB_URL 使用 Web 后端。
系统要求
- 已安装 DBX 并配置了至少一个数据库连接
- Node.js 18+
