Common questions
Is Apper MCP Connector safe?
It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed –, and the latest version (1.1.0) reached the registry today.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.
What can I use instead?
In the same category: Spec Driven Development, Remote Desktop Commander, zanadir

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/v1.1/connectTransport 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/v1.1/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.
