ChatGPT + folk: How the Official MCP Server Works
Yes, ChatGPT integrates with folk — folk runs an official remote MCP server at https://mcp.folk.app/mcp, generally available, hosted by folk with OAuth, and the vendor’s own docs list ChatGPT among the supported clients (alongside Claude, Claude Code, Cursor, and VS Code). Better still, it’s genuinely read and write: folk’s line is that “AI tools can read and write to your folk workspace just like you can” — search people, companies, and groups; create and update contacts, notes, and custom fields; manage deals and pipeline statuses. There’s no app in ChatGPT’s directory — this is a Developer Mode connection you add yourself with one URL — but among lightweight CRMs, folk’s is one of the cleanest official MCP stories going. What it doesn’t change: everything still happens in a session you’re driving, and between chats nothing watches your pipeline.
Here’s what the ChatGPT folk integration actually does, how to connect it, and what to use when you want relationship work that runs without you.
What ChatGPT can actually do with folk
- Search your whole workspace. “Who do we know at seed-stage fintech companies in the design partners group?” — people, companies, and groups, queried in plain English.
- Create and update contacts. Add a person you just met, fix a title, fill in custom fields — real writes, straight from the chat.
- Log notes. Dictate a meeting recap and have it attached to the right contact as a note.
- Manage deals and pipeline statuses. Move a deal forward, check what’s sitting in each stage, and draft the next-step email from what’s on the record.
- Prep before meetings. Pull everything folk knows about a contact — group memberships, custom fields, notes — into one brief before the call.
- Run inside agent sessions. With ChatGPT Work (launched July 9, 2026), an agent can work across folk and your other connected apps in a long, metered run — clean a group, enrich a batch, draft a set of intros. Still a run you start.
How to set it up
folk documents the connection directly at developer.folk.app/mcp/connect:
- In ChatGPT, open Settings → Apps and enable Developer Mode (Plus/Pro/Business plans where custom connectors are available).
- Add a new connector and paste the URL:
https://mcp.folk.app/mcp. - Authorize via OAuth — you log into folk and grant access; no API keys to paste.
- Ask a workspace question (“what deals are in the negotiation stage?”) to confirm the tools resolve.
The same endpoint works in Claude, Cursor, and VS Code, so one server covers your whole AI toolchain.
The limits that actually matter
- No triggers. folk’s API has full webhook support — person added to a group, deal changed — but a ChatGPT session can’t receive any of it. Events in folk never wake a chat.
- Session-bound, even in agent mode. ChatGPT Work runs are long but manually started and usage-metered — a batch errand over your workspace, not a standing watch on your relationships.
- Write access cuts both ways. ChatGPT can update deals and contacts, so treat prompts like production changes — a sloppy bulk instruction edits real records.
- Cross-stack follow-through stops at the chat. ChatGPT can draft the intro from a folk record, but it won’t send it from your inbox, set the follow-up reminder, and log the interaction back — that multi-app loop isn’t what a chat session does.
If you want folk work that runs on its own: Carly
folk people live and die by follow-through: the intro sent while the connection is warm, the nudge when a relationship goes quiet. Those moments are triggered by events and calendars — exactly what no chat session covers.
That’s where Carly fits. Carly is an AI executive assistant that acts on triggers across your whole stack, set up by conversation instead of code:
- When a person is added to a pipeline group, Carly enriches them and drafts a personalized intro email for your approval — minutes after they land, not at your next check-in.
- When a deal changes status, she drafts the next-step email and sets the follow-up reminder in folk.
- After a meeting, she logs the interaction and note on the contact and drafts the recap email.
- Every week, a relationship digest: contacts going cold in the groups you care about, each with a suggested re-engagement draft.
- No-code setup. Describe the motion in plain English; Carly interviews you and builds the workflow.
- Actually sends — drafts and sends email across Gmail and Outlook, updates records, manages tasks.
- Connects to anything — 200+ native integrations, plus any other tool via your own API key.
AI agents start at $35/month, and steps in a workflow that don’t use AI run free and unlimited. Carly natively integrates with folk.

Frequently Asked Questions
Does ChatGPT work with folk?
Yes. folk runs an official remote MCP server at https://mcp.folk.app/mcp — generally available, OAuth-authenticated, and folk’s docs explicitly list ChatGPT as a supported client. You add it in ChatGPT via Settings → Apps → Developer Mode by pasting the URL. There’s no directory app; it’s a custom connector.
Can ChatGPT write to folk, or just read?
Both. folk’s MCP is read-write: search people, companies, and groups; create and update contacts, notes, and custom fields; and manage deals and pipeline statuses. That makes it more capable than most CRM MCP servers, many of which are read-only.
Which AI tools does folk’s MCP server support?
folk’s documentation lists ChatGPT, Claude, Claude Code, Cursor, and VS Code as supported clients, all against the same hosted endpoint with OAuth. One connection pattern covers every tool.
Can ChatGPT follow up automatically when a folk deal changes?
No. folk’s API offers webhooks, but ChatGPT sessions can’t receive them — ChatGPT only acts when you prompt it. For “when a deal changes status, draft the next-step email and set the reminder,” you need a trigger-based assistant like Carly, which natively integrates with folk.

See what people say
"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
