Add the Couchbase MCP server to Windsurf

Config last verified Jun 1, 2026

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

Prerequisites

Windsurf 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 `~/.codeium/windsurf/mcp_config.json`

On Windows the file lives at %USERPROFILE%\.codeium\windsurf\mcp_config.json.

2. Add this configuration

Add to ~/.codeium/windsurf/mcp_config.json

~/.codeium/windsurf/mcp_config.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>"
      }
    }
  }
}

3. Restart Windsurf and confirm the Couchbase tools load.

Gotchas

Windsurf's Cascade reads MCP servers from an "mcpServers" object in ~/.codeium/windsurf/mcp_config.json. Unlike most clients, remote servers are configured with the "serverUrl" field rather than "url", so a config that uses "url" silently fails to connect. Native remote transport is supported without an OAuth flow.
