Add the Together AI MCP server to Windsurf

Config last verified Jun 1, 2026

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

Prerequisites

Windsurf installed.
TOGETHER_API_KEY — Together AI API key from api.together.ai/settings/api-keys. 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": {
    "together": {
      "command": "npx",
      "args": [
        "-y",
        "together-mcp@latest"
      ],
      "env": {
        "TOGETHER_API_KEY": "<TOGETHER_API_KEY>"
      }
    }
  }
}

3. Restart Windsurf and confirm the Together AI 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.
