@butterbase/mcp

The official Model Context Protocol server for Butterbase — manage schemas, auth, functions, storage, RAG, realtime, and deploys on Butterbase from any MCP-capable client (Claude Code, Claude Desktop, Cursor, Windsurf, etc.).

Install

npx @butterbase/mcp

Or install globally:

npm install -g @butterbase/mcp
butterbase-mcp

Configure

Add to your MCP client config (.mcp.json, claude_desktop_config.json, etc.):

{
  "mcpServers": {
    "butterbase": {
      "command": "npx",
      "args": ["-y", "@butterbase/mcp"],
      "env": {
        "BUTTERBASE_API_KEY": "bb_sk_your_key_here"
      }
    }
  }
}

Get an API key at butterbase.ai.

Hosted alternative

Prefer to skip the local install? Butterbase also runs a hosted MCP endpoint:

{
  "mcpServers": {
    "butterbase": {
      "url": "https://api.butterbase.ai/mcp",
      "headers": {
        "Authorization": "Bearer ${BUTTERBASE_API_KEY}"
      }
    }
  }
}
