MCP tools · 7 exposed · ~1,311 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
create_share ~300

Creates an additional tracked link for a document already on HTMLRadar, with its own recipient label, gate, password, expiry and address. One link per recipient is what separates their reading reports. It uploads nothing and creates no second copy of the document, and it cannot publish new markup: it takes a document id, which list_shares returns and share_html returned when the document was first published. The link is live the moment it is returned.

NameTypeReqDescription
allowed_email_domainsarrayOnly these email domains may open the link, e.g. ["acme.com"].
document_idstringyesThe document to make another link for — the document id from list_shares, or the one share_html returned when the document was first published.
expires_in_hoursintegerLink stops working after this many hours.
lock_deckbooleanBlocks save and print and adds a watermark; default true. Pass false for a document the recipient is meant to keep a copy of.
passwordstringExtra password gate on top of the email gate.
recipient_labelstringWho this link is for, e.g. "Acme". One link per recipient reads best.
require_emailbooleanAsk the recipient for their email before the document opens. Defaults to true.
slugstringCustom link name, so the URL reads /r/acme-proposal. Paid plans only.

No output schema declared.

No examples provided.

get_share_activity ~176

Reports whether a tracked HTMLRadar link has been opened, by whom, for how long, how far they scrolled, and which sections held their attention. Per viewer it names the five sections with the most reading time, and every figure is rounded down, so no number it prints is above the recorded one. It accepts a share id, a slug or a link; list_shares returns all three.

NameTypeReqDescription
include_detailbooleanAlso return each reader's country, city, device and referrer. Off by default: that is a named person's location and device, and whether the document was read and which parts of it is answered without…
share_idstringyesThe share id returned by share_html, or the share's slug (the part after /r/ in its link), or the link itself.

No output schema declared.

No examples provided.

list_shares ~140

Lists the account's tracked links, newest first: the slug, the recipient label, the document title, whether it has been opened and when, and the share and document ids the other tools take. This is where the identifiers for a link made in an earlier conversation come from. Returns at most 50 per call; the `before` cursor pages back through older links.

NameTypeReqDescription
beforestringCursor for the next page: the `next_before` value printed at the end of a previous list_shares result, of the form <created_at>|<share id>. Pass it back exactly as printed. Omit for the most recent l…

No output schema declared.

No examples provided.

replace_document ~156

Replaces the contents of a document already on HTMLRadar. Every existing link stays exactly as it is — same address, same settings, same reading history — and serves the new contents from the next time it is opened, so nobody is sent a second link. The new HTML is screened for phishing signals as every upload is, and the previous version is kept in the document's history. Recipients may already have read the old contents, and there is no partial update: the markup supplied replaces the document.

NameTypeReqDescription
document_idstringyesThe document whose contents are being replaced. Every link to it keeps working.
htmlstringyesThe new HTML markup, in full. It replaces the document; there is no partial update.

No output schema declared.

No examples provided.

revoke_share ~154

Switches off a tracked link that has already been sent. Anyone who opens it afterwards sees that it is no longer available, and the sender is emailed that somebody tried. This changes what a recipient can see. It is reversible — `revoked: false` switches the link back on — and it deletes nothing: the link, its settings and its whole reading history survive. Deleting a link is possible only on the website.

NameTypeReqDescription
revokedbooleanTrue (the default) switches the link off. False switches it back on.
share_idstringyesThe share id, the share's slug (the part after /r/ in its link), or the link itself. list_shares returns all three.

No output schema declared.

No examples provided.

share_html ~345

Publishes an HTML document — a deck, proposal, report or one-pager — as a tracked HTMLRadar link, and returns two addresses: the link for the recipient, and a dashboard address for the sender. The recipient sees the document as written and never the tracking. The markup goes in `html`; there is no file-path argument, so a document on disk reaches this tool only as markup the caller has already read, which leaves the user's permissions on their own file tools in charge of what is published. The link is live the moment it is returned.

NameTypeReqDescription
allowed_email_domainsarrayOnly these email domains may open the link, e.g. ["acme.com"].
expires_in_hoursintegerLink stops working after this many hours.
htmlstringyesThe HTML markup to publish, in full. There is no file-path argument: a document on disk reaches this tool only as markup the caller has already read.
lock_deckbooleanBlocks save and print and adds a watermark; default true. Pass false for a document the recipient is meant to keep a copy of.
passwordstringExtra password gate on top of the email gate.
recipient_labelstringWho this link is for, e.g. "Acme". One link per recipient reads best.
require_emailbooleanAsk the recipient for their email before the document opens. Defaults to true.
slugstringCustom link name, so the URL reads /r/acme-proposal. Paid plans only.
titlestringName shown on your dashboard. Recipients do not see it.

No output schema declared.

No examples provided.

whoami ~40

Reports the plan the HTMLRadar API key's account is on and how many of its free tracked links remain. It returns no account identifier and no email address.

Input schema present but exposes no named parameters.
