Get Started with MCP

What the OnlyFans API MCP server is, how it works, and which AI clients it supports. Covers both OnlyFans and Fansly.

What is the MCP server?

Our MCP server exposes every API endpoint as a tool that any AI agent can call. Add it once to your AI tool of choice and your agent can read chats, fans, earnings, post content, run mass messages — without you writing any code.

It's built on the open Model Context Protocol standard, so the same server works with Claude, ChatGPT, Manus, Cursor, VS Code Copilot, and any custom agent.

5 years live · 0 bans. Thousands of agencies run OnlyFans API in production today. Your AI agents ride on the same surface they do.

Both platforms, one server

The server covers OnlyFans and Fansly — 350+ tools in total, 290+ OnlyFans and 80+ Fansly. There is no separate Fansly endpoint and no second connector to install.

Fansly tools are prefixed fansly_ (fansly_listChats, fansly_sendMassMessage); OnlyFans tools are unprefixed. Your agent can work across both platforms in a single conversation.

Working with Fansly? Read Fansly over MCP — tool naming, account IDs, and the handful of Fansly behaviours an agent can't infer on its own.

MCP server URL

Same URL for every supported AI tool:

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

Prerequisites

Before you connect any AI tool:

An OnlyFans API account — free to create, no credit card required
An API key — generate one in your dashboard
At least one connected creator account — OnlyFans or Fansly

How the install works (4 steps, ~60 seconds)

Sign up + grab an API key in the OnlyFans API dashboard.

Add the MCP server URL to your AI client's connector panel.

Authorize via OAuth — you'll be redirected to OnlyFans API to approve access.

Prompt your agent. It now has 350+ tools across chats, fans, and earnings — on both OnlyFans and Fansly.

Control & safety

Built for agencies, not hobbyists:

Scoped API keys — restrict each key to specific endpoints. Read-only analyst agents and full-write ops agents in the same workspace.
Per-account permissions — limit a key to one creator or a roster.
Audit log — every API call your agent makes is logged. Review weekly.
No media stored — photos, videos, and voice notes never live on our servers.
2FA on the dashboard — mandatory for write-scoped keys.

Use scoped, per-creator keys when handing access to autonomous agents. Audit weekly.

Rate limits

MCP calls are rate-limited to 120 requests per minute per API key. If you hit this often, split work across multiple keys.
