INTEGRATIONS · MCP

One MCP URL. ChatGPT and Claude talk to your OnlyFans data.

The Only API ships a native MCP server. Connect it to ChatGPT or Claude with OAuth — no API keys, no copy-paste, no glue code. Then just ask: "who unsubscribed this week, send a campaign, restock the vault." 59 tools, all 200+ endpoints.

"Show me the top 10 fans by lifetime spend on bella_has_johnson."
"Who unsubscribed in the last 7 days and why?"
"Send a PPV campaign to all subscribers who haven't tipped this month."
"Restock the vault on @creator_x with the latest 5 uploads from Drive."
"Schedule a mass DM to expire-in-3-days subscribers offering a 30% rebill discount."

Security model

  • OAuth 2.1 + PKCE + DCR. Industry-standard auth. Each client (ChatGPT, Claude, Cursor) auto-registers via Dynamic Client Registration — no manual client IDs to wrangle.
  • Audience-bound JWTs. The issued token is scoped to one CRM panel and one MCP audience — it cannot be replayed against another tenant or a different MCP server.
  • Revoke anytime. Open the dashboard, MCP section, "Connected clients". Disconnect a client and its tokens are dead immediately.
  • Rate limits + quota guard. The MCP server enforces the same per-plan API quota as the REST API — runaway AI agents can't blow your budget.
