🗄️ 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

1. Prerequisites

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

2. 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
   

3. Claude Desktop Integration

   Add this configuration to your Claude Desktop config file:

   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>"
         }
       }
     }
   }

📚 Examples

Here are some example interactions with Claude using the MCP server:

1. List all buckets:

   Could you show me all available buckets in the database?
   

2. Create a scope and collection:

   Create a new scope called "users" and a collection called "profiles" in it
   

3. Query documents:

   Find all users who signed up in the last 30 days
   

4. Create a document:

   Create a new user document with name "John Doe" and email "[email protected]"
