README
@ngsrv/mcp
MCP server for ngsrv tunnels. Expose localhost on public HTTPS from Cursor and other MCP clients.
ngsrv is a developer tunnel tool (CLI, YAML, webhooks). This package is the optional MCP integration.
Cursor
~/.cursor/mcp.json:
{
"mcpServers": {
"ngsrv": {
"command": "npx",
"args": ["-y", "@ngsrv/mcp@latest"]
}
}
}
First tunnel.start provisions a free 12-hour device trial (no signup). Agent tokens skip the Free-tier visitor warning page.
Optional: NGSRV_API_TOKEN from ngsrv.com → API Tokens → Create agent token.
