How do AbstractAPI keys work across different services?

AbstractAPI issues a unique API key for each distinct service (e.g., one key for IP Geolocation, a completely different key for Email Validation). You must insert the API key that aligns with the specific service you want your AI agent to utilize. If you want to use multiple tools, you'll need to instantiate multiple servers or swap the keys.

Can my AI agent build a lead list using just a domain name?

Yes. Provide the domain to your agent and ask it to run the company enrichment capability. It will return the full official company name, founded year, employee count, and LinkedIn profile URL, allowing you to quickly qualify accounts before outreach.

How accurate is the Email Validation tool?

Extremely accurate. When your agent calls the Email tool, it doesn't just check the regex formatting. It probes the domain's MX records, runs real-time SMTP handshakes to ensure the inbox exists, and tests against massive databases of known disposable or role-based email addresses (like info@).

AbstractAPI + Cursor FAQ

Common questions about integrating AbstractAPI 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.
