## MCP tools (7)

### `share_html` (~345 tokens)

Share HTML as a tracked link

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.

Input parameters:

- `allowed_email_domains` (array): Only these email domains may open the link, e.g. ["acme.com"].
- `expires_in_hours` (integer): Link stops working after this many hours.
- `html` (string, required): The 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_deck` (boolean): Blocks save and print and adds a watermark; default true. Pass false for a document the recipient is meant to keep a copy of.
- `password` (string): Extra password gate on top of the email gate.
- `recipient_label` (string): Who this link is for, e.g. "Acme". One link per recipient reads best.
- `require_email` (boolean): Ask the recipient for their email before the document opens. Defaults to true.
- `slug` (string): Custom link name, so the URL reads /r/acme-proposal. Paid plans only.
- `title` (string): Name shown on your dashboard. Recipients do not see it.

### `create_share` (~300 tokens)

Make another tracked link for an existing document

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.

Input parameters:

- `allowed_email_domains` (array): Only these email domains may open the link, e.g. ["acme.com"].
- `document_id` (string, required): The 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_hours` (integer): Link stops working after this many hours.
- `lock_deck` (boolean): Blocks save and print and adds a watermark; default true. Pass false for a document the recipient is meant to keep a copy of.
- `password` (string): Extra password gate on top of the email gate.
- `recipient_label` (string): Who this link is for, e.g. "Acme". One link per recipient reads best.
- `require_email` (boolean): Ask the recipient for their email before the document opens. Defaults to true.
- `slug` (string): Custom link name, so the URL reads /r/acme-proposal. Paid plans only.

### `list_shares` (~140 tokens)

List tracked links on this account

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.

Input parameters:

- `before` (string): Cursor 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…

### `get_share_activity` (~176 tokens)

Check who read a tracked link

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.

Input parameters:

- `include_detail` (boolean): Also 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_id` (string, required): The share id returned by share_html, or the share's slug (the part after /r/ in its link), or the link itself.

### `revoke_share` (~154 tokens)

Switch a tracked link off

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.

Input parameters:

- `revoked` (boolean): True (the default) switches the link off. False switches it back on.
- `share_id` (string, required): The share id, the share's slug (the part after /r/ in its link), or the link itself. list_shares returns all three.

### `replace_document` (~156 tokens)

Replace a document, keeping every link

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.

Input parameters:

- `document_id` (string, required): The document whose contents are being replaced. Every link to it keeps working.
- `html` (string, required): The new HTML markup, in full. It replaces the document; there is no partial update.

### `whoami` (~40 tokens)

Show the HTMLRadar plan and free links left

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.

com.htmlradar/share is an MCP server listed in the public MCP registry as com.htmlradar/share. Publish HTML as a tracked link and see who opened it and which sections they read. This page covers its npm package (htmlradar-mcp).

### Is the com.htmlradar/share MCP server safe to use?

com.htmlradar/share scores 89 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 20 September 2026. It declares no install or post-install scripts. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the com.htmlradar/share MCP server expose?

com.htmlradar/share exposes 7 tools: share_html, create_share, list_shares, get_share_activity, revoke_share, and 2 more. Their descriptions and schemas cost roughly 1,311 tokens of context every time the server is loaded.

### Is the com.htmlradar/share MCP server still maintained?

com.htmlradar/share is still listed as active in the MCP registry. We last reached this channel on 20 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
