- Entity Inspection — Access detailed profile information for specific sanctioned entities, including names, aliases, and addresses.
- Deltas & Full Versions — Retrieve metadata for full list versions or just the changes (deltas) between specific versions.

Frequently asked questions
Is the OFAC SLS API Key required?
No. The SLS API is publicly accessible. However, providing an API key if you have one ensures higher rate limits and consistent access.
What is the difference between SDN and Non-SDN lists?
The SDN (Specially Designated Nationals) list contains individuals and entities whose assets are blocked. Non-SDN lists contain entities subject to other sanctions, such as sector-specific or prohibited accounts.
Can I see aliases for a specific person?
Yes! Use the get_entity_details tool with the specific Entity ID. The agent will return the full profile, including all known aliases, addresses, and identifying information.
How does LangChain connect to MCP servers?
Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.
Which LangChain agent types work with MCP?
All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
Can I trace MCP tool calls in LangSmith?
Yes. All MCP tool invocations appear as traced steps in LangSmith, showing input parameters, response payloads, latency, and token usage.
