mcp-to-cli

mcp-to-cli is a Bun-based CLI client that lets you connect to remote MCP (Model Context Protocol) servers and interact with their tools, resources, and prompts directly from the terminal.

Important: Auth URLs

When this CLI triggers an OAuth flow, it opens a browser automatically. If you are an AI agent using this skill, always pass --no-open when connecting so the auth URL is printed to the terminal instead of opening a browser. Relay the printed URL to the user and ask them to visit it. The CLI listens on a local callback server at http://localhost:8912/<connection>/callback for the OAuth redirect, so the user just needs to complete auth in their browser and it will be captured automatically.
