open-greenhouse-mcp

Production-ready MCP server for Greenhouse, designed for recruiters and hiring teams.

Most Greenhouse MCP servers mirror the API endpoint by endpoint. This one is built for recruiting teams: safe defaults, role-based profiles, and workflow tools that turn multi-step API operations into single actions.

Choose a Profile

Profile	Tools	Can write?	Recommended for
`read-only`	103	No	First-time setup, reporting, hiring managers
`recruiter`	127	Yes (safe ops)	Day-to-day recruiting work
`full`	181	Yes (all)	Admins, ops, advanced automation

Quick Start

Terminal

pip install open-greenhouse-mcp

Add to your MCP client config (Claude Desktop: ~/Library/Application Support/Claude/claude_desktop_config.json, Cursor: Settings > MCP):

config.json

{
  "mcpServers": {
    "greenhouse": {
      "command": "open-greenhouse-mcp",
      "env": {
        "GREENHOUSE_API_KEY": "your-harvest-api-key",
        "GREENHOUSE_TOOL_PROFILE": "read-only"
      }
    }
  }
}

Start in read-only mode to validate connectivity and tool behaviour, then switch to recruiter or full when you need write access.

Your API key is in Greenhouse under Configure > Dev Center > API Credential Management.

Safety

Access is limited by your Greenhouse API key permissions
Read-only profile is recommended for first setup
Destructive actions require explicit IDs — the server never infers targets
Write operations support audit attribution via GREENHOUSE_ON_BEHALF_OF
Bulk actions are rate-limited to stay within API limits

Profile Details

Recruiter includes all read tools, all screening/sourcing tools, all composite workflows, and recruiter-safe writes: reject, advance, hire, move, tag, notes, attachments, interviews, prospects, and bulk operations. It excludes job creation, user management, custom field configuration, candidate deletion, and webhook management.

Read-only skips all write operations. GREENHOUSE_READ_ONLY=true also works as a shorthand.
