From the README

# MCP Inspector

A developer tool for inspecting [Model Context Protocol](https://modelcontextprotocol.io) (MCP) servers. It ships as a single package, `@modelcontextprotocol/inspector`, that provides three ways to inspect a server:

- **Web** — a Vite + React + [Mantine](https://mantine.dev) single-page app with a Node backend.
- **CLI** — a scriptable command-line client for automation, CI, and fast agent feedback loops.
- **TUI** — an interactive terminal UI built with [Ink](https://github.com/vadimdemedes/ink).

All three run through one global `mcp-inspector` binary:

```bash
npx @modelcontextprotocol/inspector          # web UI (default)
npx @modelcontextprotocol/inspector --cli    # CLI
npx @modelcontextprotocol/inspector --tui    # TUI
```

> [!WARNING]
> **On a machine with no OS keychain, secrets are saved to a plaintext file by default.** That covers Linux without libsecret or a Secret Service, headless and SSH sessions, Termux, and containers with a mounted volume. OAuth cl
