⚠️ 베타 소프트웨어 — Hoot는 활성 개발입니다. 버그 발견? 자주 묻는 질문 기여하고 싶으신가요? PRs 환영!

빠른 시작

** (설치 없음):**

hoot.run — 브라우저에서 열기, 테스트 준비.

** 또는 로컬로 실행:**

localhost:8009에 오픈합니다. 1개의 명령, 0 구성.

특징

핵심 테스트

• ** 모든 MCP 서버에 연결 ** - HTTP 및 SSE 운송 지원
• ** 자동 감지 ** - 그냥 URL을 붙여, Hoot는 나머지를 파악 -Execute 도구 — 매개변수를 가진 시험 공구 및 전망 응답 -Copy-paste friendly — 모두 클립보드-ready입니다.

인증 및 보안

• OAuth 2.1 자동 발견 및 준수 테스트 (docs)
• **JWT 기반 세션 ** - 안전한 로컬 인증
• ** 제한 및 감사 로그 ** - 내장 보안 기능
• Localhost 전용 기본 — 현지 개발

스마트 기능

🦉 Hoot

MCP Testing Tool — Like Postman, but for the Model Context Protocol.

Test, debug, and explore MCP servers with a beautiful interface. No AI chat needed.

⚠️ Beta Software — Hoot is in active development. Found a bug? Open an issue. Want to contribute? PRs welcome!

Quick Start

🌐 Try instantly (no install):

👉 hoot.run — Opens in your browser, ready to test.

Or run locally:

npx -y @portkey-ai/hoot

Opens on localhost:8009. One command, zero config.

Features

Core Testing

• Connect to any MCP server — HTTP and SSE transport support
• Auto-detection — Just paste a URL, Hoot figures out the rest
• Execute tools — Test tools with parameters and view responses
• Copy-paste friendly — Everything is clipboard-ready

Authentication & Security

• OAuth 2.1 with automatic discovery and compliance testing (docs)
• JWT-based sessions — Secure local authentication
• Rate limiting & audit logs — Built-in security features
• Localhost-only by default — Safe for local development

Smart Features

• Intelligent tool filtering — Context-aware tool selection powered by AI
• Chat interface — Test tools conversationally with LLM assistance
• Keyboard shortcuts — Lightning-fast navigation (docs)
• 8 beautiful themes — Light & dark modes for every preference (docs)

Sharing & Collaboration

• 🦉 “Try in Hoot” links — Share servers with a single URL (docs)
• Persistent state — Your servers and tools stay configured between sessions

How It Works

Hoot runs a Node.js backend that acts as the MCP client, eliminating CORS issues when connecting to MCP servers from your browser.

Browser (React) → Backend (Node.js/Express) → MCP Servers

Architecture highlights:

• No CORS headaches — Backend handles all MCP connections
• Persistent OAuth tokens — Stored securely in SQLite (~/.hoot/hoot-mcp.db)
• Session-based auth — JWT tokens for secure frontend-backend communication
• Edge-ready — Deploy to Cloudflare Workers for global hosting (guide)
