Apper MCP

The official Model Context Protocol connector for Apper.

Build and update complete applications in Apper from AI assistants. Describe what you want, then create, update, publish, and preview it — configure its database, security and permissions, and add server-side integrations, without setting up a separate development stack.

Connect

The connector is a remote MCP server. There is nothing to install or run locally.

https://mcp.apper.io/v1/connect

Transport is streamable-http, and authentication is OAuth 2.0 — your client opens a browser to sign in to Apper on the first call.

For any MCP client that takes a JSON config:

{
  "mcpServers": {
    "apper": {
      "type": "streamable-http",
      "url": "https://mcp.apper.io/v1/connect"
    }
  }
}

Client setup

• Cursor — apperhq/apper-cursor
• ChatGPT — Apper for ChatGPT
• Claude Code — see the plugin below

Claude Code plugin

This repository also contains a Claude Code plugin that connects to the remote connector, so it can be added in one step rather than configured by hand.

See CLAUDE.md for the rules Claude follows when working with an Apper app — reading the instruction tools before generating, confirming before anything is published or deleted, and finishing the build before reporting success.

What you can do

The connector exposes tools for searching and creating apps, reading and writing project files, running and checking builds, generating previews, managing the backend schema and row-level security policies, and working with edge functions, environment keys, and secrets.

Full tool documentation lives at apper.io/learn/docs/mcp/apper-mcp-connector.
