Add the Couchbase MCP server to Claude Code

Config last verified Jun 1, 2026

The exact config to run Couchbase in Claude Code — paste it in, restart, and the tools load.

Prerequisites

Claude Code installed.
CB_CONNECTION_STRING — Connection string to the Couchbase cluster.
CB_USERNAME — Couchbase database username (or use mTLS cert/key paths).
CB_PASSWORD — Password for the Couchbase user.

Setup

1. Open `~/.claude.json`

2. Add this configuration

Add to ~/.claude.json

~/.claude.json

json

{
  "mcpServers": {
    "couchbase": {
      "command": "uvx",
      "args": [
        "couchbase-mcp-server"
      ],
      "env": {
        "CB_CONNECTION_STRING": "<CB_CONNECTION_STRING>",
        "CB_USERNAME": "<CB_USERNAME>",
        "CB_PASSWORD": "<CB_PASSWORD>"
      }
    }
  }
}

Or via CLI

bash

claude mcp add couchbase -- uvx couchbase-mcp-server

3. Restart Claude Code and confirm the Couchbase tools load.

Gotchas

Claude Code stores MCP servers under an "mcpServers" object in ~/.claude.json. It also reads a project-scoped .mcp.json and supports adding servers from the command line with "claude mcp add". Each entry must declare either a "type" or a "command"; Claude Code refuses an entry that has neither. Remote servers connect natively over Streamable HTTP with OAuth.
