Greenhouse

PyPI CI Python 3.10+ License: MIT open-greenhouse-mcp MCP server

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

pip install open-greenhouse-mcp

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

{
  "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.

What You Can Ask

• "Show me the pipeline for our Senior Engineer role"
• "Who needs my attention this week?"
• "What are our conversion rates for the Backend Intern role?"
• "Find Sarah Chen and pull up her resume"
• "Which sources are actually producing hires?"
• "Bulk reject everything inactive for 30+ days on the Account Manager role"
• "Screen this candidate for the Backend Engineer role — give me the full picture"
• "Search our engineering pipelines for anyone with Rust and distributed systems experience"
• "What new applications came in since yesterday?"

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

candidates_needing_action	Find stale applications and interviews missing scorecards
stale_applications	Applications with no activity for N days, sorted by stalest
pipeline_metrics	Conversion rates, hire/rejection rates, time-in-stage per stage
source_effectiveness	Which candidate sources produce the best hire rates
time_to_hire	Average, median, min, max days from application to hire
bulk_reject	Reject multiple applications in one call with rate-limit handling
bulk_tag	Tag multiple candidates in one call
bulk_advance	Advance multiple applications to next stage

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.

Configuration

Variable	Required	Description
GREENHOUSE_API_KEY	Yes*	Harvest API key
GREENHOUSE_BOARD_TOKEN	Yes*	Job board URL slug. *At least one required
GREENHOUSE_TOOL_PROFILE	No	full (default), recruiter, or read-only
GREENHOUSE_ON_BEHALF_OF	No	Greenhouse user ID for write audit trail
GREENHOUSE_LOG_LEVEL	No	debug, info, warning (default), error
GREENHOUSE_LOG_FILE	No	Log file path (defaults to stderr)

Logging

Structured JSON logging for observability. Set GREENHOUSE_LOG_LEVEL=info to enable:
