Your AI agent's recruiting backend
Two ways to connect your AI agents to Leonar, depending on your technical setup.
REST API
Full CRUD operations on every recruiting object. Documented endpoints, predictable JSON responses, and webhooks for real-time events. Build any workflow your team needs.
MCP Server
Connect AI agents like Claude directly to Leonar through the Model Context Protocol. Your agent can search candidates, update pipelines, and send messages, with zero custom integration code.
Your AI agent becomes a recruiter that works around the clock: sourcing candidates, pre-qualifying profiles, managing pipeline updates, and handling outreach sequences. All through a single API connection.
