Open Greenhouse MCP

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

Harvest v3. Greenhouse retired Harvest v1/v2 on 31 Aug 2026. From 0.5.0 this server uses Harvest v3 with OAuth 2.0 credentials. Upgrading from 0.4 or earlier? See Migrating from v1/v2.

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_CLIENT_ID": "your-harvest-v3-client-id",
        "GREENHOUSE_CLIENT_SECRET": "your-harvest-v3-client-secret",
        "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.

Create the credentials in Greenhouse under Configure > Dev Center > API Credentials > Create new API credentials > Harvest V3 (OAuth), and grant the scopes for the tools you plan to use. The client secret is shown once. See Advanced Setup for how tokens and scopes work.

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 the scopes on your Harvest v3 credential and the acting user's permissions
• Read-only profile is recommended for first setup
• Destructive actions require explicit IDs — the server never infers targets
• Set GREENHOUSE_USER_ID and writes are made as that user (OAuth sub), so Greenhouse's audit trail shows who did what
• Bulk actions are rate-limited to stay within API limits

Compatibility

Startup

When the server starts, it logs its configuration:

open-greenhouse-mcp v0.5.0
Profile: recruiter | Tools: 128 | Writes: recruiter-safe | APIs: harvest-v3

What's Included

• Screening & sourcing tools — 6 tools for candidate screening, resume search with boolean keywords, daily digest, and location detection
• Recruiter workflow tools — 13 composite tools for pipeline views, analytics, search, and bulk operations
• Harvest v3 API coverage — 154 tools across candidates, applications, jobs, offers, interviews, and more
• Job Board API — 13 tools for public job listings and application submission
• Optional webhooks and ingestion — 14 tools for event-driven workflows and partner integrations

Reference

Screening & Sourcing Tools

Tools for candidate evaluation and proactive talent search.

Composite Tools

High-level tools that combine multiple API calls into single operations.

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

Logging

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

{"ts": "2026-04-14T12:31:58", "level": "info", "event": "api_call", "method": "GET", "url": "...", "status": 200, "latency_ms": 245.0}
