Replit MCP Server: build and publish Replit apps from your AI assistant
Lets Claude, ChatGPT, Codex or Claude Code ask Replit Agent to build, change and publish Replit apps for you.
This is Replit's own server. You describe an app in your assistant, Replit Agent builds it on Replit, and you get a link to the live app. You can also ask questions about an app, change it, or publish it again. Every build runs Replit Agent and spends credits from your Replit account, so set a budget in Replit's billing settings first.
Good for
- People with an app idea who want a working, hosted app without writing code
- Developers in Claude Code or Codex who want to hand a side project to Replit Agent
- Designers sending a Claude design to Replit to turn it into a running app
- Replit users who want to check, update or republish their apps from a chat

Permissions
medium risk · 4 things to watch
Medium risk
A careless request can publish an app to the web or burn through your Replit credits on builds you did not want. Set a spending limit in Replit and review an app before you ask the assistant to publish it.
What it can do
- Read your data
- Create and change things
- Delete things
- Read-only mode
Watch out for
It can publish apps to the public web
The assistant can publish an app or push its latest changes live. On Replit's free plan every app is public, so check what you built before you ask it to publish. docs.replit.com
Every build spends your Replit credits
Creating or changing an app runs Replit Agent and is billed to your Replit account. Set usage limits or a budget in Replit's billing settings before you start. docs.replit.com
It can change any app you can edit
A direct connection reaches every app you can edit in the workspace you approve, including apps others shared with you. Connect a workspace that holds only what you want it to touch. docs.replit.com
Tools differ in the Claude connector
Claude's directory lists five tools and a different address than Replit's direct one, so the publish and search actions may not appear there. claude.com

Questions
What is the Replit MCP server URL?
The direct address is https://mcp.replit.com/server/mcp. Your client signs you in to Replit when you first use it. Claude's directory connector uses a separate address, https://replit-mcp.com/anthropic/mcp, and you add it from the directory without typing it.
Is it free?
The connection is free, but the work is not. Builds and changes are billed as Replit Agent usage in your Replit account. The free Starter plan works, with public apps only.
Do I need a Replit API key?
No. You sign in with your Replit account and choose a workspace. Replit says not to add a token or custom headers.
Can it work on apps I already built in Replit?
Yes, over a direct connection it can find and change any app you can edit. In ChatGPT, Replit's docs say each conversation only works on the app created in that conversation.
Can it delete my apps?
No delete action is documented. It can change apps and publish them, so the bigger risks are unwanted edits and spending.
How long does a build take?
About 2 to 3 minutes for a simple app and 3 to 4 minutes for a complex one, according to Replit. You get a link to watch it build.
Why can't I find Replit in ChatGPT?
The Replit app in ChatGPT is not available in the EU. On Business, Enterprise or Edu plans an admin has to turn it on under workspace connector settings.
Why does Replit keep asking me to authenticate?
Your sign-in has expired or was not finished. Run the sign-in again from your client, and approve the workspace you want to use.
Can I send a Claude design to Replit?
Yes. Choose Replit as the destination for a design made in Claude and it opens in Replit as a runnable app that Agent keeps building.
Why does Claude show fewer Replit tools than other clients?
Claude's directory connector is a separate endpoint with five actions. It can build, change and answer questions about apps, find one by name, and import a Claude design, but its listing has no publish, list or search actions. Clients that use the direct address get the full set.
