Install
Option 1 — Claude Code plugin (recommended)
claude plugin marketplace add https://github.com/butterbase-ai/butterbase-skills
claude plugin install butterbase
Plugin includes 30+ guided skills (/butterbase-skills:journey, /butterbase-skills:build-app, …) and auto-configures the MCP server.
Option 2 — Hosted MCP (any client)
Add to your MCP config:
{
"mcpServers": {
"butterbase": {
"url": "https://api.butterbase.ai/mcp",
"headers": {
"Authorization": "Bearer ${BUTTERBASE_API_KEY}"
}
}
}
}
Option 3 — Local stdio MCP
npx @butterbase/mcp
Or wire it up in your MCP config:
{
"mcpServers": {
"butterbase": {
"command": "npx",
"args": ["-y", "@butterbase/mcp"],
"env": { "BUTTERBASE_API_KEY": "bb_sk_..." }
}
}
}
Option 4 — Self-host the whole stack
See the Quickstart in README.md. Requires Docker + Node 22+.
Get an API key
Sign up at butterbase.ai and generate a key, or self-host and use the CLI:
butterbase keys generate
Keys are prefixed bb_sk_….
