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.

OFAC Sanctions Service + Cursor FAQ

Common questions about integrating OFAC Sanctions Service MCP Server with Cursor.

What is Agent mode and why does it matter for MCP?

Agent mode is Cursor's autonomous execution mode where the AI can perform multi-step tasks: reading files, editing code, running terminal commands, and calling MCP tools. Without Agent mode, Cursor operates in a simpler ask-and-answer mode that doesn't support tool calling. Always ensure you're in Agent mode when working with MCP servers.

Where does Cursor store MCP configuration?

Cursor looks for MCP server configurations in a mcp.json file. You can configure servers at the project level (.cursor/mcp.json in your project root) or globally (~/.cursor/mcp.json). Project-level configs take precedence.

Can Cursor use MCP tools in inline edits?

No. MCP tools are only available in Agent mode through the chat panel. Inline completions and Tab suggestions do not trigger MCP tool calls. This is by design. tool calls require user visibility and approval.

How do I verify MCP tools are loaded?

Open Settings → Features → MCP and look for your server name. A green indicator means the server is connected. You can also check Agent mode's available tools by clicking the tools dropdown in the chat panel.
