base-mcp-server

A Model Context Protocol server that provides read and write access to Feishu Base (飞书多维表格) databases. This server enables LLMs to inspect database schemas, then read and write records.

Usage

1. Install Node.js

Make sure Node.js is installed on your machine.

2. Obtain Base Tokens

Get the appToken and personalBaseToken for your base account.

3. Install MCP Server Package Globally

Install the MCP server package globally using npm:

npm install -g @lark-base-open/[email protected]

4. MCP Server Configuration

In your MCP server configuration file, add the following:

{
  "mcpServers": {
    "base-mcp-server": {
      "command": "npx",
      "args": [
        "@lark-base-open/mcp-node-server",
        "-a",
        "appToken of base",
        "-p",
        "personalBaseToken of base"
      ]
    }
  }
}

Note: If you are using Claude, you will need to add the MCP configuration through the Developer option in the Claude client settings. You can access this in the Settings menu, and then add the MCP server details under the relevant section.

tokens

You need get two tokens before using this mcp server.

• personalBaseToken: find Base Plugin UI in your base, and access Custom Plugin->Get Authorization Code

• appToken: You can obtain the appToken quickly through a Developer Tool plugin. Here’s a simplified step-by-step process on how to do it:
