upload_filePut a file online and get a short public link. Pass text directly, or base64 with encoding="base64" for binary files (images, PDFs, zips). An .html file becomes a web page; a .zip containing index.html becomes a website. Returns the URL and expires_at; anonymous callers also get a manage_token. Status may be "checking"/"publishing" (call get_link before sharing) or "unpublished" (not published). Limit 20 MB inline; use create_upload_session for bigger files.create_upload_sessionFor files too large to send inline: reserves a link and returns a one-time upload_url. PUT the raw bytes there (e.g. give the user the returned curl command), then poll get_link with the slug (and manage_token) until status is "live".publish_sitePut a web page or small static site you created online instantly. Pass {"files": {"index.html": "<!doctype html>…", "style.css": "…", "app.js": "…"}} (paths relative to the site root; index.html required). Images can go in base64_files. Returns the public URL. Pages are served sandboxed on their own link.get_linkStatus of a link: live, checking, publishing, unpublished, in_review, removed (by moderation: removed_reason + appeal_url), expired or awaiting_upload; plus expiry, size and views (null when the account’s plan has no view counts). Anonymous callers pass the manage_token they got on creation.list_linksList the links in the connected Put It Online account (newest first, permanent first). Requires a connected account.delete_linkPermanently delete a link and its files. Account owners can delete their links; anonymous callers need the manage_token. This cannot be undone.set_passwordProtect a link with a password (visitors must enter it), or pass null to remove it. Requires a connected account whose plan includes passwords; otherwise returns a subscription_required error.make_permanentTurn an expiring link into a permanent one (uses one of the plan's permanent slots; see get_account). Requires a connected account whose plan includes permanent links.extendRestart an expiring link's expiry clock (also brings back a recently expired link). Permanent links are unaffected. Requires a connected account whose plan includes extending.get_accountThe connected account's plan, permanent-link slots used/available, size limit and features.Paste either block (or both) into your client config, e.g. claude_desktop_config.json or ~/.cursor/mcp.json. We only show a config when the install command is confirmed.
