Overview

AI-generated overview

Greta is a remote MCP server that lets an AI assistant build, deploy and grow full-stack apps and websites as real hosted projects with live URLs.

What you can do
  • Build full-stack apps or self-growing websites by chatting with Greta's builder and follow each build
  • Search a marketplace of finished app templates and start a project from one
  • Deploy an app's backend and publish a website to its live address
  • Run a website's nightly growth loop with a credit cap, queue pages, review what the publish gate held, and read what each night ran and cost
  • Check projects, credits and site performance
When to use it
Useful when you want an assistant to turn a conversation into a real hosted website or full-stack app, or to deploy, publish and grow an existing Greta project without leaving the chat.
Requirements
A remote Streamable HTTP endpoint; nothing to install. OAuth 2.1 sign-in to a Greta account through the MCP client's browser flow. A Greta account with credits for building, deploying and growth runs.
Before you install
Building, deploying and growth runs consume Greta credits, so paid actions spend money; each paid action states its cost and the agent can cap a call's spend. Deploying and publishing push changes to live addresses, and the growth loop can queue and publish pages. Sign-in grants the server access to your Greta account.

Installation

In SourceWeft

  1. Open Greta in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/sh.greta%2Fgreta/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

    "greta": {
      "type": "http",
      "url": "https://mcp.greta.sh/"

README

Greta MCP server

Connect your AI agent to Greta, the AI app builder. Ask Claude, ChatGPT, Cursor or any MCP client to build you a website or an app, and Greta makes a real hosted project with a live URL, not a mockup.

This is a remote MCP server. There is nothing to install or run.

https://mcp.greta.sh

Transport: Streamable HTTP. Auth: OAuth 2.1 (your client opens a browser and you sign in to Greta).

Connect

Claude Code

bash
claude mcp add greta --transport http https://mcp.greta.sh

Then run /mcp, pick greta and sign in.

Claude.ai, ChatGPT, Cursor, VS Code and other MCP clients: add a custom connector or server with the URL above; the client signs you in to Greta.

What your agent can do

  • Build a full-stack app (frontend, backend, database) or a self-growing website by chatting with Greta's builder, and follow each build
  • Start from a template: search Greta's marketplace of finished apps and make one your own
  • Deploy an app's backend and publish a website to its live address
  • Grow a website: run its nightly growth loop with a credit cap, see what it suggests to be cited by AI answer engines, queue pages, review what the publish gate held, and read what each night ran and cost
  • Check projects, credits and how a site is doing

Building, deploying and growth runs use Greta credits. Every paid action states its cost, and the agent can cap what a call may spend.

This server asks you to sign in, so SourceWeft could not read its tools without an account and has not indexed them. What a connected account sees can depend on that account and its permissions.
