What problem does it solve?
Agents recommend wrong or outdated React Native component installs when they cannot read the current appCN registry.
Who is it for?
Solo builders shipping Expo or React Native apps who want registry-synced component help inside Claude Code or Cursor.
Skip if: Web-only React projects, teams not using appCN, or workflows that need native iOS/Android modules outside the registry.
What do I get? / Deliverables
After you run the @app-cn/mcp stdio server, your agent pulls live registry metadata so installs and component usage match appCN today.
- Accurate install commands for appCN registry components
- Usage patterns aligned to the streamed registry entry
- Fewer agent-hallucinated props or package names on mobile UI work

Common Questions / FAQ
Who is appcn for?
It is for indie developers building with React Native or Expo who adopt the AppCN component catalog and want MCP-guided installs from the live registry.
When should I use appcn?
Use it during Build frontend work when you add or refactor screens and need correct AppCN package commands and usage straight from the registry.
How do I add appcn to my agent?
Install and configure the npm stdio server @app-cn/mcp (v0.1.2) in your MCP client, optionally set APPCN_REGISTRY_URL, then restart the agent so it can query registry-backed component tools.
