Replit MCP Server

Replit MCP uses the Model Context Protocol to let you create, find, inspect, update, and publish Replit Apps from AI tools you already use.

Use Replit in ChatGPT, Claude, or Slack

Replit connects natively to ChatGPT, Claude, and Slack. Pick your platform for the connection steps and examples of what you can build there.

ChatGPT

Connect Replit from Settings → Apps & Connectors, then build apps from any conversation.

Claude

Connect Replit from the connectors directory, then ask Claude to build apps or send it a design.

Slack

Add Replit to your workspace, then ask Slackbot to build a working prototype from your idea.

Connect an MCP client directly

Use the direct connection when your MCP client does not have a Replit native integration.

Property	Value
URL	`https://replit-mcp.com/server/mcp`
Transport	Streamable HTTP
Authentication	OAuth using protected-resource discovery

Add the server URL to an MCP client that supports Streamable HTTP and OAuth authorization. The client reads Replit’s protected-resource metadata. Then it prompts you to sign in to Replit. Do not create a custom OAuth server. The Replit MCP Server provides the OAuth metadata that your client needs. You can create apps or work with apps that you can edit, including apps shared with you.

Set up Replit MCP

Codex and Claude Code are examples. You can add Replit MCP to any compatible MCP client.

Open the MCP list

In Codex, open Settings → Plugins → MCPs.

Add Replit

Add a custom MCP. Use a descriptive name such as Replit. Select Streamable HTTP. Enter https://replit-mcp.com/server/mcp and save. Do not add a bearer token or custom headers.

Tools

Tool	Required input	Optional input	Use
`create_app_from_prompt`	`appDescription`, `app_stack`	`userSpecifiedAppName`, `userQuotes`, `attachmentSummary`, `sourceReplId`	Start a new app. `app_stack` is one of `react_website`, `mobile_app`, `design`, `slides`, `animation`, `data_visualization`, `3d_game`, `document`, or `spreadsheet`. Set `sourceReplId` to start the new app as a private copy of an existing app instead of a blank project.
`search_apps`	None	`query`, `url`, `updatedAfter`, `updatedBefore`, `limit`	Find apps by title keywords, URL, or last-updated time. `limit` is 1 through 50.
`resolve_app_by_name`	`name`	None	Find one app by its exact title.
`list_apps`	None	`query`, `limit`	List apps you can edit, ordered by recent activity. The default limit is 25 and the maximum is 50.
`ask_question`	`replId`, `question`	None	Ask Agent about an app without changing it.
`update_app_using_prompt`	`replId`, `changeDescription`	`userQuotes`, `attachmentSummary`	Start an Agent update for an existing app.
`publish_app`	`replId`	None	Publish an app or republish its latest changes.
`get_publish_status`	`replId`	None	Check whether an app has been published, its current publish status, and its public URL.

Troubleshooting

Problem	What to do
Replit asks you to authenticate	Complete the OAuth sign-in flow again from your MCP client.
An app is not found	Check that you can edit the app. Then search by URL or use `list_apps` to choose from matching apps.
A create, update, or publish request is still running	Wait before retrying. For publishing, use `get_publish_status` to check the current result.
