What it is
McPorter is a TypeScript runtime and command-line tool for discovering and calling Model Context Protocol servers. It targets scripts, CLIs, and agents to access MCP tools from terminal or generated clients.
How it works
McPorter reads project and user config, imports MCP servers from various sources, and offers a runtime to list tools, call tools, emit TypeScript types, and generate CLIs. It negotiates the current MCP protocol revision (e.g., 2026-07-28) per server and supports stdio, Streamable HTTP, and legacy SSE servers. The runtime provides createRuntime(), callOnce(), and createServerProxy() with helpers to wrap results in multiple formats.
Getting started
Install methods shown in README:
npx mcporter --version
brew install steipete/tap/mcporter
# or
npm install -g mcporter
Additionally, a TypeScript runtime can be added to a project via npm/yarn/pnpm as described in the install guide. The Quick start shows inspecting a public MCP server:
npx mcporter list https://mcp.context7.com/mcp --brief
npx mcporter call https://mcp.context7.com/mcp.resolve-library-id \
