Fast terminal UI and CLI for testing, debugging, and automating Model Context Protocol servers.
STDIO, SSE, HTTP, and Streamable HTTP transports — built on the official MCP Go SDK.

# npm
npm install -g @standardbeagle/mcp-tuiLaunch the TUI against the official sample server:
mcp-tui --cmd npx --args "@modelcontextprotocol/server-everything,stdio"Or use CLI mode for scripting:
mcp-tui --cmd npx --args "@modelcontextprotocol/server-everything,stdio" tool list
mcp-tui --cmd npx --args "@modelcontextprotocol/server-everything,stdio" \
tool call echo message='hello mcp'
