The Pin MCP Server brings AI-powered candidate sourcing directly into your AI assistant. Instead of switching between tools, you can source candidates, review profiles, and trigger outreach without ever leaving your workflow.

Setting up searches

create_job starts a new candidate search from a job title, description, and your company's name and website. If you already have a posting on a job board (Greenhouse, Lever, Ashby, etc.), scrape_job_description will pull the title, location, and full description directly from the URL so you don't have to copy-paste anything. This call is throttled to 1 call per 5 minutes to combat abuse.

Reviewing candidates

get_candidates returns up to 10 top-ranked, unreviewed candidates for a given search. Each profile includes enough context to make a call. From there, accept_candidate moves a candidate into your outreach sequence and kicks off email contact automatically. reject_candidate passes on a candidate and immediately sources a replacement, keeping the queue full. You can supply a structured rejection reason or free-text note to help the system learn your preferences over time.

Refining searches

modify_search lets you adjust any criteria using plain language — things like "only candidates in New York" or "require 5+ years of Python experience" — without rebuilding the search from scratch. If you've rejected several candidates in a row, recalibrate_search applies all of your accept/reject feedback to source a fresh, better-matched batch.

Listing searches

list_jobs returns all active searches on your account, filterable by job title, so you can quickly navigate between open roles.

Usage Cost

create_job and modify_search will each cost one MCP look up credit when used. You can review your limit and how many credits you've used via MCP and how many you have remaining by going to settings->MCP Server. In the below example, the client has 500 look up credits, 270 total used, and 4 credits have been consumed from MCP usage.

In Claude, head over to Customize.

In Customze, click on the "+" icon, then choose "Add Custom connector"

In "Add Custom connector" put Pin as the name and https://mcp.pin.com/mcp as the URL.

After adding the custom connector, hit the connect button and walk through the process of authenticating Pin with Claude.

When you're finished authenticating, you should see something like this. Pin's MCP tools are generally all safe so we recommend setting to "always allow" to avoid needing to give Claude permissions at each step.

Now you're all set. Just start a new chat with Pin to start sourcing for a role.

If you need a more in-depth tutorial, you can check out our "How to use Pin MCP" webinar recording:

To keep things running smoothly for everyone, our MCP integration uses a few layers of rate limiting:

Overall usage limit Every user can make up to 60 requests per minute and 800 requests per hour, across all actions combined.

Creating jobs Creating a new job search is limited to 2 per minute, to prevent accidental duplicate submissions.

Viewing candidates Pulling candidate lists has its own limits to keep things fast:

If you hit the daily candidate limit, you'll still see candidate IDs — you just won't see full profile and contact details until the limit resets.

Everything else All other actions (viewing jobs, updating searches, accepting/rejecting candidates, pipeline summaries, etc.) are only subject to the overall usage limit above — no special restrictions.

Q: Does Pin MCP work with ChatGPT?

Yes. Pin MCP works with ChatGPT, as well as Claude, Claude Code, and Codex. MCP access requires a paid Pin subscription.

Q: Why can't I find Pin in ChatGPT's Apps or Connectors directory?

Pin isn't listed in ChatGPT's public directory yet. OpenAI's review process for directory listings can take several months. In the meantime, you can connect Pin by adding it as a custom connector.

Q: How do I connect Pin MCP to ChatGPT?

Add Pin as a custom connector in ChatGPT using this server URL:

https://mcp.pin.com/mcp

When prompted, sign in with your Pin account to authorize the connection. Once it's added, Pin will appear in your connector list and you can toggle it on in your chats.

Q: I've authenticated and turned on Developer mode, but Pin still doesn't show up. What's wrong?

Pin won't appear on its own, even after you authenticate or enable Developer mode. You need to add it manually as a custom connector with the URL above. After that, it will show up in your connector list.

Q: What can I do with Pin in the MCP?

The MCP is built for sourcing workflows. You can list your jobs, start or adjust searches, pull candidate batches, and accept, reject, or shortlist candidates. It doesn't return reporting data yet, such as outreach stats or reply rates. For those, use Pin's in-app reporting.
