OFAC Compliance for LangChain AI Agents

The problem

LangChain powers thousands of production agents. LangChain itself has no compliance tools. Every agent that touches money is exposed to OFAC violations unless screening is added.

Code example

from langchain_community.tools import AgentMailCheck
  from langchain.agents import AgentExecutor, create_react_agent
  from langchain_anthropic import ChatAnthropic

  tool = AgentMailCheck(api_key=os.getenv("AGENTMAIL_KEY"))
  llm = ChatAnthropic(model="claude-sonnet-4-5")
  agent = create_react_agent(llm, [tool], prompt)
  chain = AgentExecutor(agent=agent, tools=[tool], verbose=True)
