Overview
Free App hosting. Set your price, get paid. One-click publish to the growing MCP ecosystem. Connect your GitHub repo and publish to MCP Community Registry.
You built something useful -- a tool, an API, a data source. AI assistants like Claude, Cursor, and Windsurf want to use it. mctx lets you host it and get paid when they do.
No infrastructure to manage. No payment integration to build. Just your code and a GitHub repo.
Note: An App on mctx is an MCP server — same technology, hosted and monetized on the mctx platform. Developers build and deploy Apps; subscribers use them through their AI clients. You may see "MCP server" in technical documentation and code — it refers to the same thing.

How it works
1. Build your App (~5 min)
An App on mctx is an MCP server — a program that exposes tools, data, or workflows to AI assistants like Claude. mctx handles hosting, auth, payments, and discovery -- you focus on your server logic. Start from the example template or follow the framework getting-started guide.
2. Connect your GitHub repo (~1 min)
Link your GitHub account and install the mctx GitHub App. mctx reads your package.json for configuration -- no custom config files.
3. Add your App (~2 min)
Select your repository and configure your first App for deployment.
4. Set up payouts (~5 min)
Complete a one-time payout setup so we can send you money. Required before your first deploy.
5. Add support email (~1 min)
Provide a verified support email so subscribers can reach you. Required before your first deploy.
6. Deploy & publish (~1 min)
Click deploy. mctx pulls your code, deploys it to your-app.mctx.ai, and runs a health check. Your App is live. One-click publish to the MCP Community Registry.
