Connect Replit

Replit Agent, across your projects

Replit Agent connects to MCP servers from Replit's cloud. Once you add Thndr, Agent can use it in any of your projects.

Server URLhttps://mcp.thndr.app/mcp

Add the server

  1. In Replit, open Integrations and go to MCP Servers.
  2. Click + Add MCP server.
  3. Enter a Display name, for example Thndr, and the MCP Server URL https://mcp.thndr.app/mcp. Leave Advanced settings empty: Thndr signs you in, so there is no header or key to add.
  4. Click Test & save. A Thndr sign-in page opens.
  5. Sign in, tick the tools you want Replit Agent to use, and press Allow.
  6. Approve the request in the Thndr app on your phone. Check that the number on your phone matches the one on screen.

Thndr then appears under MCP Servers with its status.

Try it
