Butterbase Skills

Claude Code plugin for Butterbase — an AI-native backend-as-a-service with Postgres, auth, storage, serverless functions, an AI gateway, RAG, realtime, and durable objects.

This plugin gives Claude deep knowledge of Butterbase's 40+ MCP tools, ships 30+ guided skills, and auto-configures the MCP server connection.

What you get

• Auto-configured MCP server — .mcp.json points Claude at https://api.butterbase.ai/mcp with your BUTTERBASE_API_KEY. All Butterbase tools available immediately.
• Always-on context — CLAUDE.md teaches Claude Butterbase's environment, branding, tool shape, and core workflow.
• Guided journey — /butterbase-skills:journey walks any idea from brainstorm → plan → schema → auth → functions → deploy → optional hackathon submission.
• Per-capability skills — schema-design, auth-setup, function-dev, deploy-frontend, debug-rls, storage, rag-dev, realtime, durable-objects, ai, migrations, substrate, integrations, payments, and more.

Install

bash
# Add the marketplace
claude plugin marketplace add https://github.com/butterbase-ai/butterbase-skills

# Install the plugin
claude plugin install butterbase

Setup

Sign-in is OAuth — no API key copy-paste needed.

1. Sign up at butterbase.ai.
2. Install the MCP server across every detected client:

bash npx @butterbase/cli mcp install The cli walks Claude Code, Cursor, VS Code, JetBrains, Codex, Gemini CLI, and the rest, and prints per-client OAuth hints.

1. Trigger OAuth once per client. In Claude Code: restart, then run /mcp (or claude mcp login butterbase).

Supported AI assistants

• Claude Code (primary) — installed via the plugin marketplace command above; npx @butterbase/cli mcp install also covers it.
• Claude Desktop / Cursor / VS Code / JetBrains / Codex / Gemini CLI / others — npx @butterbase/cli mcp install writes the right config for each, then a single /mcp (or the client's equivalent) launches the OAuth flow in your browser.
• Any other MCP-capable client can connect to https://api.butterbase.ai/mcp directly — the server advertises OAuth 2.1 via the standard .well-known/oauth-protected-resource metadata. Or run the MCP server locally via @butterbase/mcp.
