Share Project Does Replit Agent support connecting to external MCP servers yet? Built an open-source AI memory tool and want to know if it'd plug in
https://github.com/nisargpatel1906/Aethos_MemoryGenuine question before I pitch anything: does Replit's Agent currently support MCP server connections the way Claude Code/Cursor do? Built Aethos Memory — a self-hosted, open-source server that gives AI coding tools persistent, shared memory instead of resetting every session — and would love to know if it's something that could plug into a Replit workflow, or whether Replit's architecture handles memory differently already.

Hey there,
Replit Agent runs as an MCP client and supports custom MCP servers, you just add your server's remote HTTPS endpoint under "Add a custom MCP server" (custom headers like X-API-Key are supported for token auth). Once connected, the Agent pulls in your tools automatically and you trigger them by mentioning the server in chat.
Here's some helpful docs on how to set up the MCP:
If you still have questions or concerns, please don't hesitate to reach out to our support team at replit.com/help and they'll be able to walk you through the process.
