Track recruitment activity inside Claude Desktop

This CATS ATS integration lets your AI client read hiring pipelines without forcing you to open another browser tab. Calling `list_recruitment_activities` pulls recent interview notes and candidate status updates straight into your chat window. You ask Claude for a status report, and it reads the actual ATS database to build it. Digging deeper requires specific data. When you need the exact requirements for an open role, `get_job_details` fetches the compensation band and required skills. Your agent formats that data instantly, so you spend less time clicking through menus and more time reviewing actual qualifications.

Search and filter candidate pools

Sifting through hundreds of applicants takes hours manually. Running `search_candidates` through this MCP Server filters your entire talent pool based on specific criteria like location or experience level. Claude takes your plain English request and translates it into a precise database query. Checking individual profiles happens just as fast. The `get_candidate_details` tool grabs resumes, contact info, and past interview feedback for any specific person. You get the full picture of an applicant delivered right to your desktop app or web interface.

Map client companies and contacts

Agency recruiters need to know who they are hiring for at all times. Firing off `list_recruitment_companies` shows you every active client currently stored in your system. Claude can then cross-reference those companies with open job orders to show where your priorities lie. Finding the right hiring manager is the next step. By executing `list_recruitment_contacts`, your agent pulls the names and emails of the decision-makers at those companies. You have everything needed to draft an update email to a client without leaving the chat.

Common questions about CATS ATS MCP in Claude Desktop

Open your settings and navigate to the Developer tab. Edit the claude_desktop_config.json file to include the Vinkius endpoint token. Restart the app completely to load the new tools.

No. This specific integration only reads data. You get access to tools like `list_candidates` and `get_job_details`, but writing new records requires logging into the actual ATS.

Your API token might lack the right permissions. Check your Vinkius dashboard to ensure the endpoint is active. Then run `list_job_orders` again to test the connection.

Yes. You plug the remote URL directly into the Integrations menu on the web application. The custom MCP connector handles the authentication without requiring local config files.

Vinkius runs this connection through an isolated V8 sandbox. Resume details, salary histories, and interview notes pulled via `get_candidate_details` never sit in persistent storage. The environment destroys itself the moment your session ends.
