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.

About OFAC Sanctions Service MCP Server

Connect to the OFAC Sanctions List Service (SLS) API through your AI agent and explore authoritative data on sanctioned individuals, groups, and entities using natural conversation.

Pydantic AI validates every OFAC Sanctions Service tool response against typed schemas, catching data inconsistencies at build time. Connect 10 tools through Vinkius and switch between OpenAI, Anthropic, or Gemini without changing your integration code. full type safety, structured output guarantees, and dependency injection for testable agents.

What you can do

List Discovery — Retrieve identifiers for all available sanctions lists, including the Specially Designated Nationals (SDN) and Consolidated Non-SDN lists.
Update Monitoring — Check the timestamp of the last update for any sanctions list to ensure you are using the most current data.
Version Tracking — List historical and current versions of sanctions lists and retrieve specific version metadata.
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.
Entry Metrics — Get the total count of entities within a specific list version for audit purposes.
Tag Management — List all descriptive tags and labels associated with list versions.

The OFAC Sanctions Service MCP Server exposes 10 tools through the Vinkius. Connect it to Pydantic AI in under two minutes — no API keys to rotate, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.

OFAC Sanctions Service + Pydantic AI FAQ

Common questions about integrating OFAC Sanctions Service MCP Server with Pydantic AI.

How does Pydantic AI discover MCP tools?

Create an MCPServerHTTP instance with the server URL. Pydantic AI connects, discovers all tools, and generates typed Python interfaces automatically.

Does Pydantic AI validate MCP tool responses?

Yes. When you define result types as Pydantic models, every tool response is validated against the schema. Invalid data raises a clear error instead of silently corrupting your pipeline.

Can I switch LLM providers without changing MCP code?

Absolutely. Pydantic AI abstracts the model layer. your OFAC Sanctions Service MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
