Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

    Auth is not required, so the OAuth metadata check does not apply.

Capabilities

Tools 11

get_feedback

Read recipient comments, page paths, pointed-at elements (selector and visible text), and approval or change-request decisions. The status filter selects open, resolved, or all feedback.

Discovered
get_page

Details for one page: address, visibility, recipients and who opened it. Optional filePaths reads exact uploaded source files from that version, up to 20 files and 256 KB total, with text or base64 encoding. An empty filePaths array returns a bounded manifest without file contents.

Discovered
get_profile

Identify the AttachPage account connected to this agent.

Discovered
list_pages

List the user's pages with recipient and open counts.

Discovered
notify_recipients

Email existing active recipients that a page has been updated, with an optional note. Each recipient receives a fresh personal link. Sends email immediately; sent email cannot be recalled.

Discovered
publish_anonymous_page

Publish a public web page without an account or API key. It is deleted 48 hours after publishing unless the user opens the returned claimUrl and signs in. Returns the page URL, the claimUrl and tellUser: always relay tellUser and the claimUrl, and tell the user to keep the page before sending it to anyone. If the user gives an email address, pass it as reminderEmail: the claim link is emailed now and again before deletion.

Discovered
publish_document

Publish a PDF, Word (.docx), PowerPoint (.pptx), Excel (.xlsx/.xls), or CSV file as a browser-viewable page, private by default. Accepts filename and base64 content, up to 4 MB decoded. Documents become readable PDFs, slides have presentation controls, and spreadsheets have searchable sheet tabs. Preserves the original for download. A siteId replaces the page at the same address. Does not send invitations.

Discovered
publish_page

Publish a web page as the connected user. A siteId replaces an existing page at the same address. preserveFiles retains omitted assets and requires the baseDeploymentId of that version; stale edits are refused. Visibility is private (invitation-only, default) or public. Requires an authenticated AttachPage connection.

Discovered
resolve_feedback

Mark recipient feedback as resolved, or reopen it with resolved: false. The recipient sees the updated resolution status.

Discovered
send_page

Email personal invitations for a page to the specified recipient addresses, with an optional message and access expiry. Sends email immediately; sent email cannot be recalled.

Discovered
update_page

Rename a page, change its address label (slug), or switch private/public.
