🌐 HTTP Prompt Reloaded

Stateful Interactive API Navigation & Agentic MCP Engine.
The legendary 9.1k-star CLI REPL resurrected for modern Python (3.10–3.13) and upgraded into an autonomous AI Agent tool.

⚡ What is HTTP Prompt Reloaded?

Modern API exploration is broken: developers drown in bloated Electron apps (Postman/Insomnia) or struggle with massive, fragile cURL commands. The original httpie/http-prompt was brilliant, but broke down under ancient prompt_toolkit < 2.0 constraints.

HTTP Prompt Reloaded revives this concept as a zero-dependency, pure Python engine that bridges human developers and autonomous AI agents:

1. Navigate APIs like a File System: cd /api/v1/users, cd 42, cd ..
2. Persistent Session Context: Headers (Bearer tokens, cookies) and query parameters persist across requests.
3. Dual Operation:
   • Interactive CLI REPL for human terminal power users.
   • Native Model Context Protocol (MCP) JSON-RPC 2.0 Server for AI Agents (Claude Desktop, Cursor, Antigravity, Open-WebUI).
4. Hardened Security: Built-in SSRF protection (blocks cloud metadata endpoints like 169.254.169.254), CRLF header injection guards, and canonical URL traversal sanitization.

📦 Installation

# Via pip
pip install http-prompt-reloaded

# Or run instantly via uv / pipx
uvx http-prompt-reloaded http://localhost:8080

🚀 Human CLI Quickstart

# Start an interactive session on your API
http-prompt-reloaded https://api.github.com

# In the prompt:
/> cd /users/tastenkasperle
/users/tastenkasperle> header User-Agent MyDevAgent/1.0
/users/tastenkasperle> get
--> 200 https://api.github.com/users/tastenkasperle (112ms)
{
  "login": "tastenkasperle",
  ...
}

/users/tastenkasperle> cd /repos
/repos> param sort updated
/repos> get

🤖 MCP Integration for AI Agents

Give your AI coding assistants the power to test, explore, and debug live REST APIs with memory instead of spitting out static cURL strings!
