portgraph

ci npm JSR Rust license

One line: npx portgraph (or bunx portgraph): live local port topology (Docker + Ollama/LM Studio/vLLM) as a terminal TUI and stdio MCP server.

Install

Bun / npm:

bunx portgraph
npx portgraph

# or install in your project / globally
bun add -d portgraph
npm i -D portgraph

JSR:

bunx jsr add @kanchingyg/portgraph
npx jsr add @kanchingyg/portgraph

Cargo (Rust native binary):

cargo install --git https://github.com/kanchingyg/portgraph

The scan engine and MCP stdio server are written in Rust (src/lib.rs, src/main.rs, src/mcp.rs). TypeScript under src/*.ts is included for npx / bunx / JSR usage and MCP bridge helpers when no native binary is present.
