🗄️ Couchbase MCP Server for LLMs

A Model Context Protocol (MCP) server that enables LLMs to interact directly with Couchbase databases on Capella clusters. Query buckets, perform CRUD operations, execute N1QL queries, and manage data seamlessly through natural language.

🚀 Quick Start

Prerequisites
- Node.js 16 or higher
- A running Couchbase instance on Capella
- Claude Desktop application

Installation

Couchbase MCP Server can be installed in two ways:

Option 1: Using NPX (Recommended)

The quickest way to get started is using NPX:

npx -y @couchbasedatabase/couchbase-mcp

Option 2: Manual Installation

If you prefer to clone and run the project manually:

# Clone the repository
git clone https://github.com/Aniket310101/MCP-Server-Couchbase.git
cd MCP-Server-Couchbase

# Install dependencies
npm install

# Build the project
npm run build

Claude Desktop Integration

Windows: %APPDATA%/Claude/claude_desktop_config.json
MacOS: ~/Library/Application Support/Claude/claude_desktop_config.json

Option 1: With Package Installation

{
  "mcpServers": {
    "couchbase": {
      "command": "npx",
      "args": ["-y", "@couchbasedatabase/couchbase-mcp"],
      "env": {
        "COUCHBASE_URL": "<COUCHBASE CONNECTION STRING>",
        "COUCHBASE_BUCKET": "<BUCKET NAME>",
        "COUCHBASE_USERNAME": "<COUCHBASE USERNAME>",
        "COUCHBASE_PASSWORD": "<COUCHBASE PASSWORD>"
      }
    }
  }
}

Option 2: With Manual Installation

{
  "mcpServers": {
    "couchbase": {
      "command": "node",
      "args": ["path/to/MCP-Server-Couchbase/dist/index.js"],
      "env": {
        "COUCHBASE_URL": "<COUCHBASE CONNECTION STRING>",
        "COUCHBASE_BUCKET": "<BUCKET NAME>",
        "COUCHBASE_USERNAME": "<COUCHBASE USERNAME>",
        "COUCHBASE_PASSWORD": "<COUCHBASE PASSWORD>"
      }
    }
  }
}
