Amplify MCP server

Make browser games from your AI agent. Describe a game, and Amplify builds a playable browser version in your Amplify account. Keep changing it by prompt, follow the build, preview it, and ask to publish it at its own address. Amplify builds web apps and websites the same way.

This repository has no server code. It holds the connection config for Amplify's hosted MCP server, plus ready-made plugin and extension manifests for Claude Code, Cursor and Gemini CLI.

You need an Amplify account. You can create one at amplify.is.

Connect

Your client registers itself and opens Amplify's sign-in and consent page in the browser the first time it connects. There is nothing to paste except the URL.

Claude Code

claude mcp add --transport http amplify https://app.amplify.is/mcp

Or install this repository as a plugin:

/plugin marketplace add Gudmundur76/amplify-mcp
/plugin install amplify@amplify

Then run /mcp and choose amplify to sign in.

Claude (web and desktop)

Cursor

Add to ~/.cursor/mcp.json (or .cursor/mcp.json in a project):

{
  "mcpServers": {
    "amplify": {
      "url": "https://app.amplify.is/mcp"
    }
  }
}

This repository is also a Cursor plugin (.cursor-plugin/plugin.json and mcp.json).

VS Code (GitHub Copilot)

Add to .vscode/mcp.json:

{
  "servers": {
    "amplify": {
      "type": "http",
      "url": "https://app.amplify.is/mcp"
    }
  }
}

Gemini CLI

gemini extensions install https://github.com/Gudmundur76/amplify-mcp

Or add it to ~/.gemini/settings.json:

{
  "mcpServers": {
    "amplify": {
      "httpUrl": "https://app.amplify.is/mcp"
    }
  }
}

Run /mcp auth amplify in Gemini CLI to sign in.

Other clients

Any MCP client that supports remote Streamable HTTP servers with OAuth can connect with just https://app.amplify.is/mcp. For a stdio-only client, use a bridge such as npx -y mcp-remote https://app.amplify.is/mcp.

Sign-in and consent

When you connect, Amplify asks you to sign in and shows a consent page where you choose:

• Permissions (scopes): read, build and publish. Grant only what you need.

• Projects: all projects, only the projects this connection creates, or a single project.

• Daily credit cap for this connection.

You can disconnect a client at any time under Account → Connected apps in Amplify. Every tool call is logged. Access tokens last one hour, and your client refreshes them for up to 30 days.

Scopes

Credits and the two-step confirmation

Building and editing spend credits from your own Amplify account. Every spending call is two-step:

1. The agent calls create_project, create_build or edit_project. Nothing runs yet. Amplify answers needs_confirmation with the price and a single-use confirmToken.

2. The agent shows you the price. Only after you agree does it call confirm_action with the token. A token works once, on that connection only, within 10 minutes.

Spending also counts against the connection's daily credit cap. When the cap or your balance runs out, the call stops and says how much is needed and where to top up.

Tools

The server shows only the tools your granted scopes allow.

Read (read, read-only)

Build (build, spends credits, two-step)

Publish (publish)

The server has no delete, billing or payment tools.

Example prompts

• "Make a one-button endless runner where a fox jumps over logs, with a high score."

• "Change the fox to a penguin and make the logs icebergs."

• "What's the status of my last build? Send me the preview link."

• "Run the publish check on my runner game and tell me what would block it."
