Add the turbopuffer MCP server to Claude Code

Config last verified Jun 1, 2026

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

Prerequisites

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

Setup

1. Open `~/.claude.json`

2. Add this configuration

Add to ~/.claude.json

~/.claude.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>"
      }
    }
  }
}

Or via CLI

bash

claude mcp add turbopuffer -- npx -y @turbopuffer/turbopuffer-mcp@latest

3. Restart Claude Code and confirm the turbopuffer tools load.

Gotchas

Claude Code stores MCP servers under an "mcpServers" object in ~/.claude.json. It also reads a project-scoped .mcp.json and supports adding servers from the command line with "claude mcp add". Each entry must declare either a "type" or a "command"; Claude Code refuses an entry that has neither. Remote servers connect natively over Streamable HTTP with OAuth.
