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.
