Built for AI Agents

Tunnels your agent can drive.

rustunnel gives AI agents public HTTPS, TCP, and UDP URLs for anything running on localhost — webhook testing, sharing a dev server, letting another agent or device reach a local port. One MCP server, six tools, copy-paste config for every harness.

brew tap joaoh82/rustunnel && brew install rustunnel

Set up your harness

Claude Code

One-command plugin install — Claude Code gets six tunnel tools and cleans tunnels up on session exit.

Cursor

Drop one JSON file in .cursor/ and Cursor's agent can expose any port it just started a server on.

Windsurf

Cascade manages tunnels through the same MCP server — config lives in one Codeium JSON file.

Any MCP client

Claude Desktop, Codex, Cline, or your own agent — one stdio MCP server, six tunnel tools.

Machine-readable surfaces
