Bifröst · developer tunnel

A stable public URL for your local MCP server.

Bifröst is a developer tunnel built for AI connectors. Expose your machine at a durable {id}.tunnel.heimech.com that survives restarts — so ChatGPT and Claude keep their connection and you stop re-importing URLs.

How it works

One binary. One stable URL.

  • Stable subdomains across restarts — reserve yours with Bifröst Pro.
  • Streams SSE and MCP straight through — no buffering.
  • Gate any tunnel behind Heimech login with Access — owner, allowlist, or entitlement.
  • One command: bifrost --id my-mcp --port 3000. Rust, rustls, no OpenSSL.
terminal
$ bifrost --id my-mcp --port 3000
◆ tunnel up
  https://my-mcp.tunnel.heimech.com  →  localhost:3000
  stable across restarts · SSE/MCP ready

Stop re-importing URLs.

Give your local MCP server a home. The free tier gets you an ephemeral URL; Bifröst Pro makes it yours for good.
