LangChain and LangGraph
langchain-mcp-adapters turns the server into LangChain tools.
API key
Setup
Load the tools and give them to any agent.
Pythonfrom langchain_mcp_adapters.client import MultiServerMCPClient import os client = MultiServerMCPClient({ "zomler": { "transport": "streamable_http", "url": "https://api.zomler.com/mcp", "headers": {"Authorization": f"Bearer {os.environ['ZOMLER_API_KEY']}"}, } }) tools = await client.get_tools()
What you get
One tool per platform, plus capabilities and check_balance, at https://api.zomler.com/mcp. Every answer is the envelope: what was measured, when, what was left out and why, and what it cost. Fresh fetches spend credits; anything already held is free.
Keys are created under API keys in the dashboard, where each one's calls and spend are listed. Revoking a key stops this client on its next call. The same key also calls the REST API.
