LangChain is the most popular framework for building LLM-powered applications. Connect LangChain agents to Jarvis SDK to unlock 700+ modules — text processing, API integrations, data transformation, and more — without building custom tools.
pip install langchain langchain-community requests
Sign up at jarvissdk.com and create an API key from your dashboard.
Wrap Jarvis SDK's REST API as a LangChain Tool.
Pass the tool to your LangChain agent's tool list.
Copy this into your project to get started immediately.

Your LangChain agent describes its mission, Jarvis SDK returns the perfect toolkit. Dynamic tool selection without hardcoding.
Pipe outputs between modules or run parallel executions in a single API call — perfect for complex LangChain chains.
Every module has a trust score. Your agent can automatically prefer certified, battle-tested tools.
No — it adds to them. Keep your existing tools and add 700+ more from Jarvis SDK. They work alongside each other.
Yes. If your LangChain setup supports MCP, point it at jarvissdk.com/api/mcp. All 700+ modules are accessible via MCP's JSON-RPC 2.0 protocol.
