Ink-based TUI that shows exactly what an LLM sees through MCP.
Browse tools/resources/prompts, execute them, and see raw JSON-RPC
traffic in a protocol log. Supports gated session flow with
begin_session, raw JSON-RPC input, and session reconnect.
- McpSession class wrapping HTTP transport with typed methods
- 12 React/Ink components (header, protocol-log, menu, tool/resource/prompt views, etc.)
- 21 unit tests for McpSession against a mock MCP server
- Fish + Bash completions with project name argument
- bun compile with --external react-devtools-core
