Metalift LangChain integration
LangChain tools for Metalift — a hosted web context API that turns URLs into LLM-ready markdown for agents. This package wraps the Metalift REST API; it does not use @langchain/community RecursiveUrlLoader or any local server-side HTTP fetch of user-supplied URLs.
Get an API key
- Sign up for Metalift Cloud and verify your email.
- Complete onboarding on the dashboard.
- Copy your API key from Dashboard → API keys.
New accounts receive 1,000 free credits/month on the Free tier. Use the Metalift Cloud API at https://api.metalift.ai.
Do not commit API keys into source code — pass them at runtime or via the METALIFT_API_KEY environment variable.
Security
- All URL fetching runs on the Metalift scrape API with SSRF guards: manual redirect validation, private/metadata IP blocklist, DNS pinning, and Playwright egress isolation.
- Do not use LangChain's built-in
RecursiveUrlLoader(or similar loaders with automatic redirect following) for untrusted URLs — see CVE-2026-27795 and Metalift security.
Usage
pip install metalift-langchain
from metalift_langchain import get_metalift_tools
tools = get_metalift_tools(api_url="https://api.metalift.ai", api_key="YOUR_API_KEY")
Requires the metalift-sdk package and a reachable Metalift scrape API.
