Add the Couchbase MCP server to VS Code

Config last verified Jun 1, 2026

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

Prerequisites

VS 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 `.vscode/mcp.json`

2. Add this configuration

Add to .vscode/mcp.json

.vscode/mcp.json

json

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

Heads up

VS Code uses the `servers` key (not `mcpServers`) and requires `type`.

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

Gotchas

VS Code uses the `servers` key (not `mcpServers`) and requires `type`.

VS Code is the exception to every other client: its top-level key is "servers", not "mcpServers", and each entry needs an explicit "type" (for example "http" or "stdio"). Secrets are not inlined; instead you declare an "inputs" array and reference each value as ${input:id}, so VS Code prompts for it once and never writes it to disk. Remote servers connect natively with OAuth.
