Litmus is a Y Combinator-backed technical hiring platform that turns repositories, engineering tickets, and job descriptions into structured, project-based technical assessments and interview pipelines tailored to how a team actually ships. It evaluates candidates on both code quality and development process, lets them work in their own IDE or terminal, and captures AI-tool usage (Claude Code, Copilot CLI) transparently. Candidate management syncs with the Ashby, Greenhouse, and Lever applicant-tracking systems. Litmus exposes a bearer-key REST API (roles, invites, submissions) and an official hosted Model Context Protocol (MCP) server for agent-driven access to submissions, candidates, pipeline status, and assessment authoring.
