Notes and caveats
- Codex setup is documented only as UI steps (Settings > Plugins > MCPs, add custom Streamable HTTP server, no bearer token or headers), so no Codex snippet is given.
- Replit also offers native connectors for ChatGPT, Claude and Slack; plan availability is described on the Replit in ChatGPT and Replit in Claude pages.
- Only apps the user can edit are reachable.
- Not to be confused with Replit Agent's ability to connect to third-party MCP servers.
- No public source repository is linked.
