mcpg.ai — AI assistant for MCPG configurations.

An AI assistant trained on MCPG's plugin catalog, config schema, and deployment patterns. It generates working YAML, refactors existing configs, and walks through deployments — all in a chat interface.

What it knows

  • The 38-plugin catalog (identity, policy, security, reliability, observability, transforms, payments, bindings, backends, credential)
  • The MCPG config schema (bindings, identity chains, policy chains, plugins, observability, tenancy, control_plane, tls)
  • Common deployment shapes (single-binary, Docker, Helm, multi-instance HA)
  • Security rules (no plaintext secrets, default-deny policy, mTLS pinning)
  • The license tier model and which plugins gate at which tier

How it works

Two modes:

  • Real LLM mode — Set ANTHROPIC_API_KEY on the server, or paste a key in Settings. Streams from Claude with an MCPG-specific system prompt.
  • Demo mode — No API key needed. Recognizes common patterns and returns hand-curated MCPG configs. Useful to see what the UI does without spinning up a key.

Privacy

Chats and projects are stored locally in your browser's localStorage. They don't sync across devices. They're not sent anywhere except to Anthropic via /api/chat (when you're using a real API key). Clear them in Settings.

Companion sites

  • mcpg.dev — product site, docs, plugin catalog, pricing
  • mcpg.link — paste a config, get a shareable validated URL
  • mcpg.cloud — managed hosting + multi-tenant control plane

Self-host

The mcpg.ai app is open source under Apache-2.0. Run it locally with pnpm --filter @mcpg/ai dev. Set ANTHROPIC_API_KEY in .env.local for real LLM responses.
