Which ChatGPT plan do I need?

You need a Pro, Business, or Enterprise seat — those are the tiers where ChatGPT lets you add a custom MCP connector. Free and Plus can’t add one yet. With Business or Enterprise, a workspace admin approves the Fansly API connector a single time and it shows up for every seat, so chatters never have to touch the setup screen themselves.

How much can the agent do on its own?

As much as your tool approvals allow. Treat mass messages and posts as drafts: the agent writes the copy, a person sends it. Read-only work — earnings summaries, subscriber lookups, chat recaps — is safe to let run end to end without stopping for approval.

Is it safe to put my Fansly accounts behind an AI?

Fansly API already serves 500+ Fansly accounts for 50+ developers across 30+ platforms, and ChatGPT talks to the same MCP endpoint they use. You approve access yourself over OAuth, every API key is capped at 120 requests per minute, and you can disconnect the connector from ChatGPT at any time.

Can I limit a GPT to certain creators?

Yes, two ways. Soft: every fansly_ tool takes a fanslyAccount ID (fansly_acct_…), so a Custom GPT’s instructions can pin it to the creators one team handles. Hard: scope permissions in your Fansly API dashboard — keys can be limited to specific creators and endpoints — and give the analyst GPT and the ops GPT separate connectors.

How does this compare to Claude?

ChatGPT wins when you need one Custom GPT rolled out to many seats, or Deep Research across months of subscriber history. Claude wins for long autonomous runs and code-heavy automation through Claude Code or the Anthropic API. Plenty of agencies keep both connected — see the Claude guide at /mcp/claude.

Before you start

ChatGPT custom connectors require a paid plan with MCP support (Pro, Business, or Enterprise). On Business and Enterprise, an admin can approve the connector once and roll it out to every seat in your workspace.

How do I connect ChatGPT to Fansly?

In the connector panel, paste the MCP URL, set Authentication to OAuth, then connect — ChatGPT needs OAuth for this server so authorization completes correctly.

01
In ChatGPT, open Settings → Connectors → Create (Pro / Business / Enterprise plans).
02
Paste the Fansly API MCP server URL. Set Authentication to OAuth — Fansly API MCP expects OAuth for ChatGPT connectors.
MCP server URL
```
https://app.onlyfansapi.com/mcp/onlyfans-mcp?platforms=fansly
```
03
Click Connect and finish the OAuth flow. Done — your agent now has 80+ tools across chats, fans, and earnings.

Give your team a Fansly Custom GPT

Go to Explore GPTs → Create → Configure, paste the system prompt below into Instructions, and add the Fansly API connector under Tools. Share it with your chatters and swap {{Agency Name}} for yours.

System prompt

You are a Fansly agency analyst for {{Agency Name}}.

You have access to:
- The Fansly API MCP connector. Every tool is prefixed fansly_ (fansly_listAccounts, fansly_listChats, fansly_sendChatMessage, fansly_sendPost, and 80+ more).
- Each tool's description and schema inside the connector. Read them before you guess at a parameter.

Rules:
- Start with fansly_listAccounts. Every other tool needs a fanslyAccount ID in the form fansly_acct_XXXXXXXXXXXXXXX.
- Prices are in thousandths of a dollar: 1000 = $1.00, 10000 = $10.00. Convert before you report a number.
- Use UTC timestamps. Name the tool and parameters you used in every answer.
- For earnings questions, break results down per Fansly account unless told otherwise.
- For chat messages, mass messages, and posts: return draft text only. Never call a send tool. A human reviews and sends.
- Media goes in as a file_url and comes back as an upload ID; reference that ID when a post or message needs an attachment.
- There is no separate For-You-Page tool. FYP visibility is a parameter on fansly_sendPost.
- Point out refunds, unusual spend, and top supporters going quiet without being asked.

Tone: short, numbers first, written for agency operators. No emojis unless asked.

Put recurring work on Agent Mode

Agent Mode is where ChatGPT works unattended — it plans, calls tools, and loops through multi-step jobs on its own. Paste the prompt below and a daily earnings digest lands every morning without anyone lifting a finger.

Agent Mode prompt

Every morning at 8am UTC, write a Slack-ready summary of the last 24 hours of earnings per Fansly account using the fansly_ tools (amounts arrive in thousandths of a dollar — convert to USD). Flag any account down more than 25% on the day before, any refund above $50, and any top supporter who sent nothing yesterday. Output as markdown.

Set tool approvals so write tools (fansly_sendChatMessage, fansly_sendPost, list edits) wait for a human OK. Read-only tools — earnings, subscriber lookups, chat history — can run on their own.

Let Deep Research dig through your subscriber cohorts

Deep Research is ChatGPT’s long-form investigation mode — built for questions that span hundreds of subscribers. Pull whatever the fansly_ tools expose, then let it group the data and propose what to test next.

Deep Research prompt

Investigate why subscribers lapse across my top 100 supporters this quarter. Use the fansly_ tools to collect last activity, total spend (thousandths of a dollar — convert), message count, and list membership for each supporter. Separate the cohort that let their subscription end from the cohort that renewed, then rank 3 hypotheses by expected lift.
