Four-Leaf MCP

Open source and MCP install

Last updated: 2026-10-15 Canonical URL: https://four-leaf.ai/oss Machine-readable mirror of https://four-leaf.ai/oss for agents and LLMs.

Install the Four-Leaf MCP server or Claude Skill in Claude, Cursor, ChatGPT, Cowork, Cline, Continue, Windsurf, or Perplexity.

Four-Leaf runs two open surfaces alongside the paid product. Both are free to install, integrate, cite, and extend.

Two install paths

Hosted MCP server. A Model Context Protocol server at https://four-leaf.ai/api/mcp, streamable HTTP with OAuth 2.1, PKCE, and Dynamic Client Registration. It works in any MCP-aware client, including Claude Code, Claude Desktop, Cursor, ChatGPT Desktop, Cowork, Cline, Continue, Windsurf, and Perplexity.

The fastest install:

claude mcp add --transport http four-leaf https://four-leaf.ai/api/mcp

Other clients add it through their own connector settings. ChatGPT requires Plus, Pro, Business, Enterprise, or Education with Developer Mode enabled; free ChatGPT accounts cannot install MCP servers. Perplexity requires Pro, Max, or Enterprise. On the first tool call the client opens a browser for Four-Leaf login.

four-leaf-coach Skill. An MIT-licensed Skill that turns Claude Code, Cursor, OpenAI Codex, or GitHub Copilot into a guided job-search and interview-prep coach backed by the same hosted MCP.

The fifteen tools

list_roles, get_role_intelligence, get_interview_questions, explain_interview_format, search_jobs, get_job, generate_practice_questions, score_answer, match_score, comp_coach, comp_benchmarks, list_applications, save_application, start_voice_mock_interview, and tailor_resume.

A free Four-Leaf account is required. Thirteen tools work on a free account; start_voice_mock_interview and tailor_resume need paid access, which the 3-day trial also grants. The compute tools carry daily caps on free accounts and free trials, and a paid subscription lifts them. Per-tool arguments, limits and sample prompts are on the page this mirrors.

Access can be revoked at any time from the connected-apps settings in your Four-Leaf account.
