ChatGPT x OnlyFans

What this does

ChatGPT can call OnlyFans API endpoints directly through the OnlyFans MCP server. Add it once as a custom connector, then build a Custom GPT for your team or fire off Agent Mode to run scheduled work overnight.

Works with Custom GPTs, Agent Mode, Deep Research, and any chat with the connector enabled.

Prerequisites

• An OnlyFans API account
• A paid ChatGPT plan (Pro, Business, or Enterprise)
• At least one connected OnlyFans account

Step-by-step

1. Open ChatGPT Settings → Connectors

In ChatGPT, click your profile → Settings → Connectors → Create.

2. Add a custom connector

Enter these details:

• Name — OnlyFans MCP (or any label you prefer)
• MCP server URL:

https://app.onlyfansapi.com/mcp/onlyfans-mcp

• Authentication — set to OAuth

3. Click "Connect" and finish OAuth

ChatGPT redirects you to app.onlyfansapi.com. Click Authorize.

You'll land back in ChatGPT with the connector marked as connected. Done — your agent now has 200+ tools across chats, fans, and earnings.

4. Enable the connector in a chat

Open a new chat. Click the tools picker → toggle OnlyFans MCP on.

Build a Custom GPT for your agency

In ChatGPT, go to Explore GPTs → Create → Configure. Drop this into Instructions, attach the OnlyFans MCP connector under Tools, and share with your team.

Replace {{Agency Name}} with your agency:

You are an OnlyFans agency analyst working for {{Agency Name}}.

You have access to:
- The OnlyFans MCP server — search the docs for endpoints, schemas, and webhook events.
- The onlyfansapi-skill — call REST endpoints to read chats, fans, earnings, and trigger mass messages.

Rules:
- Always check the docs first when unsure of a parameter.
- Use UTC timestamps. Always quote the source endpoint and parameters in your final answer.
- For revenue questions, group by creator account unless the user says otherwise.
- For mass-message drafts, output text only — never auto-send. The user reviews and dispatches.
- Surface chargebacks, refunds, and unusual spend patterns proactively.

Tone: concise, numeric, agency-operator-friendly. No emojis unless asked.

Run scheduled work in Agent Mode

Agent Mode is ChatGPT's autonomous workspace — it can plan, run tools, and iterate over multi-step tasks. Use it to ship a daily revenue digest with zero human touch:

Every morning at 8am UTC, draft a Slack-ready report of last 24h revenue per creator.
Flag any chargeback over $50, any creator whose revenue dropped >25% vs yesterday,
and any whale who didn't message yesterday. Output as markdown.

Run cohort analysis in Deep Research

Deep Research is ChatGPT's long-form research agent — perfect for cohort analysis across hundreds of fans:

Research churn drivers across my top 100 fans this quarter.
Pull last_active, total_spend, message_count, and tags from the OnlyFans API REST endpoints.
Cluster the churned cohort vs the retained cohort and surface 3 hypotheses ranked by lift.

Example use cases

8 prompts that replace daily ops grunt work. Drop them into your Custom GPT or any ChatGPT conversation with the connector enabled:

• "Pull this week's revenue per creator and chart it." — replaces the Monday-morning spreadsheet build
• "List my top 50 spenders with their last message timestamp." — no more switching dashboards per creator
• "Find every fan flagged for chargeback in the last 30 days." — catch chargeback patterns before finance does
• "Draft a renewal DM for fans churning in the next 7 days. No auto-send." — agent drafts, your team approves and ships
• "Compare PPV conversion rates across my creators this month." — see which creator's offers are working
• "Build a daily report for Slack: revenue, top fans, chat backlog." — one Custom GPT replaces a recurring n8n workflow
• "Identify whales who haven't messaged in 14 days — draft a re-engagement." — reactivate dormant high-spenders before they unsub
• "Export all transactions over $200 from last quarter as CSV." — accounting stops chasing you for reports
