# ChatGPT x OnlyFans (/onlyfans-ai/mcp/chatgpt) import { Accordion, Accordions } from "fumadocs-ui/components/accordion"; ChatGPT × OnlyFans MCP ## 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. ChatGPT custom connectors require a paid plan with MCP support — **Pro**, **Business**, or **Enterprise**. Free and Plus do not yet support custom MCP connectors. ## Prerequisites * An [OnlyFans API](https://app.onlyfansapi.com) account * A paid ChatGPT plan (**Pro**, **Business**, or **Enterprise**) * At least one [connected OnlyFans account](/introduction/guides/connect-onlyfans-account) On **Business** and **Enterprise**, an admin can approve the connector once and roll it out to every seat in your workspace. ## 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** The OnlyFans MCP server expects **OAuth** for ChatGPT connectors. Don't pick "No authentication" — the connector will fail. ### 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. Sign in to [app.onlyfansapi.com](https://app.onlyfansapi.com) in a separate tab first, so the OAuth flow doesn't stall on the sign-in page. ### 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. ``` A Custom GPT replaces a recurring n8n / Zapier workflow with one URL your team can open from any device. ## 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. ``` Configure tool approvals so **write actions** (mass-message, label updates) require a human OK. Read-only actions (earnings, fan lookups) can run unattended. ## 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 Most tools are **account-scoped** and need the account id in the form `acct_XXXXXXXXXXXXXXX`. If you omit it, ChatGPT will ask — or it will call `list_accounts` first to find one. ## Troubleshooting Check that **Authentication** is set to **OAuth** (not "No authentication"). Sign in to [app.onlyfansapi.com](https://app.onlyfansapi.com) in a separate tab first, then retry. MCP calls are rate-limited to **120 requests/minute** per API key. Wait a minute and retry. If you hit this often, split work across multiple API keys. The connector is toggled off in that conversation. Open the tools picker and toggle **OnlyFans MCP** on. Custom MCP connectors require **Pro**, **Business**, or **Enterprise**. Upgrade your plan, or use [Claude](/onlyfans-ai/mcp/claude) instead — Claude supports custom connectors on every paid plan. ## See also * [OnlyFans MCP overview](/onlyfans-ai/mcp) — what MCP is, how it works, and supported clients * [Claude MCP install guide](/onlyfans-ai/mcp/claude) * [Manus MCP install guide](/onlyfans-ai/mcp/manus) * [Develop with AI Agents](/introduction/guides/develop-with-ai-agents) — `llms.txt`, OpenAPI schema, `onlyfansapi-skill` * [API Reference](/api-reference) — every endpoint exposed as an MCP tool
