Add the turbopuffer MCP server to Windsurf

Config last verified Jun 1, 2026

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

Prerequisites

Windsurf installed.
TURBOPUFFER_API_KEY — turbopuffer API key used to authenticate SDK calls. Required.

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": {
    "turbopuffer": {
      "command": "npx",
      "args": [
        "-y",
        "@turbopuffer/turbopuffer-mcp@latest"
      ],
      "env": {
        "TURBOPUFFER_API_KEY": "<TURBOPUFFER_API_KEY>",
        "TURBOPUFFER_REGION": "<TURBOPUFFER_REGION>",
        "TURBOPUFFER_DEFAULT_NAMESPACE": "<TURBOPUFFER_DEFAULT_NAMESPACE>"
      }
    }
  }
}

3. Restart Windsurf and confirm the turbopuffer 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.
