FuncHub

⚠️ Security Warning: FuncHub dynamically loads and executes code from remote Git repositories. Only install tools from sources you trust, and use in isolated environments.

FuncHub is a bilingual (Python + NestJS) tool registry and dynamic loader designed for AI Agents. It allows developers to publish, discover, install, and dynamically invoke tool functions.

Features

• Dual SDKs: Python SDK + NestJS SDK, sharing the same design philosophy
• Semver version management: Supports ^1.2.3, 1.x, latest, branch names, etc.
• GitHub publishing integration: Automatic Fork + PR workflow via GitHub API v3
• Cache management: .version file tracks installed versions; expired cache auto-refetches
• Private registry support: Supports custom indexes and mirrors via config
• Safety confirmation: Interactive confirmation on install; --yes to bypass

5. Use a Tool in Code

Python:

from funchub import FuncHub

hub = FuncHub()
scraper = hub.load("web_scraper")
result = scraper(url="https://example.com")

NestJS:

import { FuncHub } from '@funchub/nestjs';

const hub = new FuncHub();
const scraper = await hub.load('web_scraper');
const result = await scraper({ url: 'https://example.com' });

Command Reference

Publishing a Tool

1. Create a funchub.json or funchub.yaml tool definition file in your project root:

{
  "name": "my_tool",
  "description": "My awesome tool",
  "version": "1.0.0",
  "entry_point": "src/index:handler",
  "parameters": {
    "type": "object",
    "properties": {
      "input": { "type": "string" }
    }
  }
}

2. Publish:

funchub publish --version v1.0.0

If you have write access to the registry repo, the tool is committed directly. Otherwise, a Fork + PR is automatically created.

Decorator Usage (Python)

from funchub import funchub_tool

@funchub_tool(
    name="web_scraper",
    description="Scrape web page title",
    version="1.0.0"
)
def scrape_url(url: str) -> str:
    """Scrape the title from a URL."""
    import requests
    from bs4 import BeautifulSoup
    resp = requests.get(url)
    soup = BeautifulSoup(resp.text, 'html.parser')
    return soup.title.string if soup.title else "No title found"
