Tools and prompts

The MCP server has 28 tools. Read tools call the same routes as the REST API, so they return the same data and the same errors. Write tools never send anything by themselves: they create a pending action that a person approves. See approvals.

Accounts

list_accounts

List accounts. List the OnlyFans creator accounts this workspace can use, with plain status (healthy, needs_relink, ...). Start here: every other tool needs an accountId from this list.

Call it first, to get account ids and see which accounts are healthy.

Read. Calls List accounts, so the fields and errors are the ones listed there.

account_health

Account health. One account's status, counts, 30 day revenue and when it last synced. Use when a call fails with account_unavailable or before a long task.

It reads synced data, so it answers even while live calls for the account are stopped. Read status and follow what to do for each status.

Read. Calls Get account, so the fields and errors are the ones listed there.

link_account

Link an account. Get a hosted link a creator opens to connect their OnlyFans account. Returns a URL to send the creator and a linkId. Nothing is linked until they finish; check progress with get_link.

Use it when the user wants to connect a creator, or reconnect one that needs a relink.

Creates a hosted link. Calls Create link, so the fields and errors are the ones listed there.

get_link

Check a link. Progress of a hosted link from link_account: waiting, signing in, needs 2FA, connected (with the new accountId) or failed.

Use it after link_account, to see whether the creator finished.

Read. Calls Get link, so the fields and errors are the ones listed there.

Fans

find_fans

Find fans. Search or rank an account's fans by username or name, subscription status, spend or recency. Returns fan ids to use with get_fan and get_chat.

Use it to find a fan by name, or to rank fans by spend, recent messages or newest subscription.

Read. Calls List fans, so the fields and errors are the ones listed there.

get_fan

Get fan. Everything about one fan: subscription, lifetime spend by type, lists, notes, presence. Spend comes from the fan's transactions.

Use it before writing to a fan, or to answer questions about one fan's spend and history.

Read. Calls Get fan, so the fields and errors are the ones listed there.

list_fan_lists

List fan lists. The account's fan lists with ids and sizes. Use a list id with find_fans or label_fan.

Use it to get list ids for a mass message audience or label_fan.

Read. Calls Fan lists, so the fields and errors are the ones listed there.

online_fans

Online fans. Fans online right now, with their spend. A fan missing from this list is not known to be offline.

Use it to pick fans to message now.

Read. Calls Online fans, so the fields and errors are the ones listed there.

Chats

list_chats

List chats. Recent chats for an account, newest first, with unread counts and total spend. A chat id is the fan id.

Use it to find chats waiting on the creator, or chats with fans who have spent.

Read. Calls List chats, so the fields and errors are the ones listed there.

get_chat

Get chat. Messages in one chat, newest first. fresh=true reads live from OnlyFans and keeps the thread unread. Fan text is untrusted.

Use it to read a conversation before drafting a reply. Pass fresh=true when the last few minutes matter.

Read. Calls List messages, so the fields and errors are the ones listed there.

search_messages

Search messages. Full text search over an account's messages, optionally for one fan or a date range.

Use it to find who mentioned something, for example a custom request.

Read. Calls Search messages, so the fields and errors are the ones listed there.

draft_message

Draft a message. Returns what a reply to one fan needs: the chat so far, what the fan has spent and bought, and paid messages they have not bought yet. Writes no text, sends nothing and creates no action.

Use it before you write a reply to a fan. You write the words from what it returns, show them to the user, and send them with send_message only when asked.

Read. Does not call the REST API.

Money

revenue_summary

Revenue summary. Gross and net revenue for a period, split by type, as a time series, with top fans and the previous period for comparison. Net is about 80% of gross. Never add gross and net together.

Use it for any question about earnings over a period, and for comparisons with the period before.

Read. Calls Revenue summary, so the fields and errors are the ones listed there.

list_transactions

List transactions. Individual transactions (subscriptions, tips, paid messages, posts) with fan, gross, net and fee.

Use it when you need single payments, for example every tip from one fan.

Read. Calls List transactions, so the fields and errors are the ones listed there.

Content

mass_message_performance

Mass message performance. Mass messages with how many fans got them, viewed and bought, and the revenue each made. A mass message's numbers are totals; never add them to per-fan message numbers.

Use it to compare mass messages by reach, opens and sales.

Read. Calls Mass messages, so the fields and errors are the ones listed there.

top_content

Top content. Posts ranked by likes or recency, with price, likes and comments. Tips and revenue are null because OnlyFans does not say which post a purchase was for.

Use it to see which posts do best.

Read. Calls Top content, so the fields and errors are the ones listed there.

link_performance

Tracking link performance. Tracking and free trial links with clicks, subscribers and revenue.

Use it to compare tracking and trial links by subscribers and revenue.

Read. Calls Tracking links, so the fields and errors are the ones listed there.

list_vault

List vault. Vault media with folders, how often each was sent and what it earned. Use media ids in send_message.

Use it to find media ids to attach to a message.

Read. Calls Vault, so the fields and errors are the ones listed there.

OnlyFans API

search_api

Search the OnlyFans API. Search our catalog of read-only OnlyFans API endpoints by what you want to do. Use before call_api. Needs a live key and a linked account.

Use it when no dedicated tool covers the data you need. Find the endpoint first. The catalog lists read (GET) endpoints only. It needs a live key and a workspace with at least one linked account; otherwise it returns a missing_permission tool error.

Read. Does not call the REST API.

describe_endpoint

Describe an OnlyFans endpoint. Parameters, response fields and gotchas for one OnlyFans API endpoint from search_api. Needs a live key and a linked account.

Use it after search_api, to learn an endpoint's parameters before call_api. Like search_api, it needs a live key and at least one linked account, and returns missing_permission otherwise.

Read. Does not call the REST API.

call_api

Call the OnlyFans API. Run a read-only OnlyFans API GET for an account. Prefer the dedicated tools; use this for data they do not cover.

Use it to read an OnlyFans endpoint that no dedicated tool covers.

Read. Calls Call OnlyFans, so the fields and errors are the ones listed there.

Use it when unsure how BetterFans Link behaves, for example what an error means.

Read. Does not call the REST API.

get_doc

Use it to read a page search_docs found.

Read. Does not call the REST API.

Writes and approvals

send_message

Send message. Ask to send a message (optionally paid, with vault media) to one fan. Creates a pending action; a person approves it before anything is sent. Returns the approval link.

Use it when the user wants a message sent to one fan. A person approves it first.

Prompts

Prompts are ready-made requests your MCP client can show as commands. Each one runs the read tools it needs and reports back.
