Hey everyone, we're the team behind mcp-use, the open-source MCP framework with 10k GitHub stars and ~10M+ downloads.

Manufact is the cloud platform that gets your product onto the Claude Connectors marketplace and the ChatGPT (Codex) Plugin Store via MCP.

The problem

Paul Graham recently tweeted: "AI apps are the new browsers".
Your customers now do most of their work inside Claude and ChatGPT, and the connector marketplaces are a new distribution channel: someone installs your product in one click and uses it inside the chat they already live in.

We listed Manufact on Claude and saw a surge of signups that is still going on now.

But shipping a production-ready MCP server is its own project:

• MCP is a protocol evolving fast .
• Auth is easy to get wrong.
• Every client behaves differently.
• The stores have their own conformance requirements, and review can block you for weeks.

How Manufact works

Manufact is the cloud built specifically for MCP:

• Push to deploy. Connect the GitHub App once and every commit ships a new version of your MCP server, with a preview deployment for each PR.
• Test every MCP tool and MCP-UI widget in the cloud inspector.
• Know the moment your MCP breaks in ChatGPT or Claude with automatic cross-client testing.
• Publishing checklists so your MCP app doesn't get stuck in marketplace review.
• Auto-generated submission assets (logo, copy, screenshots).
• Analytics, session replay, and traces built in for MCP, so you can see how it's used and why tools fail.

Your product's UI inside the chat

A plain MCP server lets the agent read and write your data.
An MCP App goes further: it's an MCP server that can return a UI as the result of a tool call, so your actual product interface renders inside Claude or ChatGPT. The user sees your charts and forms instead of a wall of text.

Ferruccio Balestreri (Amplitude) put it well:

since mcp ui was released in claude we got a 2x boost in retention.

With the mcp-use SDK you write a normal React component, drop it in, and it registers as an MCP UI resource automatically.

Backstory

We've been building on MCP since the protocol shipped. It started with the mcp-use SDK, the full-stack framework for MCP servers and apps. We kept watching companies struggle to take those servers to production, so we built the cloud for it (mcp-use is to Manufact what Next.js is to Vercel).

Manufact is now the #1 recommended deployment option in OpenAI's docs.

We've helped startups from recent YC batches like AgentMail and Item get onto the Claude Connectors marketplace, and larger companies in finance, insurance, and marketplaces run their MCP apps on Manufact in production.

Our asks

1. Have an MCP server? Deploy it on Manufact.
2. Thinking about building an MCP App? Copy our prompt for agents and your coding agent will guide you.
3. Trying to get listed on the marketplaces? Book a call with us. We have publishing checks and direct contacts on the MCP teams at Anthropic and OpenAI.

Hope to see your MCP on manufact.com, or that you at least learned something new. 🙂
