Verdict

Pick Couchbase MCP Server if you want a local (stdio) server that keeps data on your machine, and you need the broadest set of tools.

Pick InstantDB MCP if you prefer the more popular, battle-tested option, and you want a hosted/remote server with nothing to install.

Add Couchbase MCP Server

Install / run

uvx couchbase-mcp-server

Paste into ~/Library/Application Support/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "couchbase-mcp-server": {
      "command": "uvx",
      "args": [
        "couchbase-mcp-server"
      ],
      "env": {
        "CB_CONNECTION_STRING": "couchbases://connection-string",
        "CB_USERNAME": "username",
        "CB_PASSWORD": "password"
      }
    }
  }
}

Requires `uv` (the Python package runner). Install it from https://docs.astral.sh/uv/ if `uvx` is not found.

Add InstantDB MCP

Install / run

npx -y @instantdb/mcp --token <token>

Paste into ~/Library/Application Support/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "instantdb-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://mcp.instantdb.com/mcp"
      ]
    }
  }
}

Claude Desktop connects to remote servers through the `mcp-remote` proxy (installed on first run via npx). Restart Claude Desktop after saving.
