Sign-in and security

  • OAuth 2.1, authorization code with PKCE (S256 only).
  • You approve on a UniLink screen; nothing happens until you click Allow.
  • Access tokens last 1 hour. Refresh tokens rotate: each one works once.
  • Changing your password, logging out everywhere or changing MFA ends the grant.
  • Disconnect any time in Account settings → Connected apps.
  • Discovery: https://unilink.us/.well-known/oauth-protected-resource/mcp and https://unilink.us/.well-known/oauth-authorization-server.
  • Client registration: Client ID Metadata Documents from claude.ai and chatgpt.com. Dynamic Client Registration is not supported.

First call

For people building an MCP client: what the server answers before sign-in, and what to do next.

curl -i -X POST https://unilink.us/mcp
HTTP/1.1 401 Unauthorized
WWW-Authenticate: Bearer resource_metadata="https://unilink.us/.well-known/oauth-protected-resource/mcp", Bearer
  1. Read resource_metadata: it names the authorization server, https://unilink.us.
  2. Fetch https://unilink.us/.well-known/oauth-authorization-server for the authorize and token endpoints.
  3. Run the authorization code flow with PKCE (S256); the person signs in and clicks Allow.
  4. Send the access token as Authorization: Bearer on every POST.

Only client IDs on claude.ai and chatgpt.com are accepted. Building your own client? Use the REST API with an API key.

Edit

Changes your page

Create a block

Create a new block on a profile page. Common types: link, text, faq, contact, html, video, map, timer, gallery, banner, shop, digital, appointment, event, course, donation, tip. A new link block starts with no links; add them with add_link_item. A new text block starts with placeholder text under a "Text" heading; replace both with update_text_block. Call list_blocks to get the new block's UID.

    Profile ID

  • pageIdintegeroptional

    Page ID (the Page shown by list_blocks). Omit or 0 for the profile's main page.

  • typestringrequired

    Position index (0 = top)

update_text_block

Overwrites content

Set the text of a text block

Set the text of an existing TEXT block (type 'text' in list_blocks), replacing what is there. A text block shows one tab unless its owner turned tabs on; this always writes the first tab. text is plain text; line breaks become paragraphs. HTML or other markup is not interpreted: it shows as typed.

Arguments

  • profileIdintegerrequired

    Profile ID

  • blockUIDstringrequired

    UID of a text block (from list_blocks)

  • textstringrequired

    The new text, at most 10000 characters

  • titlestringoptional

readOnlyHint: falsedestructiveHint: trueidempotentHint: trueopenWorldHint: true

Errors

  • A tool that fails returns a normal result with isError: true and a text message saying what went wrong (for example "Error: text must be 10000 characters or fewer.").
  • Some refusals are ordinary answers, not errors: "This is available on a paid UniLink plan.", "Link limit for your plan reached.", "Profile not found or access denied."
  • There are no stable error codes. Read the message and relay it to the person.
  • An unknown tool or method gets a JSON-RPC error.

Pagination

These tools take take and skip. The others return everything in one call.

Limits

  • add_link_item counts the profile’s live links against your plan’s link limit; at the limit it answers "Link limit for your plan reached."
  • Links to onlyfans.com, fansly.com and fanvue.com need a paid plan.
  • Link URL: at most 511 characters. Link title: at most 512.
  • Text block text: at most 10 000 characters, plain text. Heading: at most 512.
  • list_repeat_customers returns at most 100 per page.
  • Request body: up to 1 MB.
