Replit Launches Native MCP Server for ChatGPT, Claude, and Slack

ReplitView original changelog

Replit launched a native MCP (Model Context Protocol) server, allowing ChatGPT, Claude, Slack, and any compatible MCP client to connect directly to Replit. Users can now create, find, inspect, update, and publish Replit apps — or duplicate an existing app to edit — entirely from within their AI assistant's chat interface. The move turns Replit into a callable backend for other AI tools rather than a standalone destination, extending Replit's reach to wherever developers already work.

Key Takeaways

  • Replit now ships a native MCP server, letting ChatGPT, Claude, Slack, and any MCP-compatible client connect directly to the platform.
  • Connected clients can create, find, inspect, update, and publish Replit apps without leaving their chat interface.
  • Users can duplicate an existing app privately to edit, instead of starting every project from a blank canvas.
  • The integration positions Replit as a backend other AI tools can call into, reducing context-switching for developers.
  • Slack teams can turn a feature request typed in a channel into a published, working app without leaving the conversation.
  • The launch extends a broader pattern of Replit appearing as a build destination inside partner AI products.

Building Replit Apps From Inside Other AI Tools

Replit rolled out native support for the Model Context Protocol (MCP), letting users connect Replit directly to ChatGPT, Claude, Slack, or any MCP-compatible client and drive Replit Agent without ever opening replit.com. Once connected, a user can ask their AI assistant of choice to create, find, inspect, update, and publish Replit apps — all from within the host application's chat interface.

What You Can Do

Through the Replit MCP Server, compatible clients gain access to actions that create a new app from a natural-language description, search existing apps, inspect an app's state, push updates, and publish changes live. Users can also spin up a private copy of an existing app to edit, rather than starting from a blank project — useful for iterating on someone else's public Replit app without touching the original.

Why It Matters

This update turns Replit into a backend that other tools can call into, rather than a destination users must visit directly. A developer working inside Claude or ChatGPT can now describe a feature, have Replit Agent build and publish it, and stay in their existing workflow the entire time. For teams that live in Slack, the same capability means turning a feature request typed in a channel into a working, published app without a context switch.

This follows a broader industry trend of AI coding tools exposing themselves as MCP servers so they can be orchestrated by general-purpose assistants, and puts Replit alongside a growing list of platforms that treat Replit as a build target reachable from anywhere.
