HTML to PDF Skill

Overview

HTML to PDF works by converting the HTML content provided into a PDF file. It uses advanced algorithms to convert the HTML content into a PDF file and returns the PDF file.

The tool

Once your client is connected to the VerveKit server, this appears in its tool list as HTMLtoPDFSkill. It is read-only and open-world — it fetches and never mutates anything on your side — so most clients call it without asking you to confirm.

Tool call

{
  "name": "HTMLtoPDFSkill",
  "arguments": {
    "html": "<html><body><h1>Hello World</h1><p>This is a sample PDF document.</p></body></html>"
  }
}

You do not name the tool yourself; the model picks it. Asking about <html><body><h1>Hello World</h1><p>This is a sample PDF document.</p></body></html> in the terms this skill covers is enough for it to reach for HTMLtoPDFSkill on its own — naming it explicitly also works, and is the way to force the call.

Connecting

One server URL covers every skill in the catalog, including this one. Authorization is OAuth: the client opens a browser once, and there is no key to paste into a config file.

{
  "mcpServers": {
    "vervekit": {
      "url": "https://api.vervekit.com/v1/mcp"
    }
  }
}

Per-client setup — Claude, Cursor, VS Code, ChatGPT — is on the MCP setup page.

Arguments

These are the properties on the tool's inputSchema, so a well-behaved client validates them before the call is made. Premium arguments are accepted on every plan but only take effect on plans that include them.

Argument	Type	Description
`html`Required	string	The HTML content to convert to PDF. Ensure that the HTML is escaped properly length 0–500000
`marginTop`OptionalPremium	number	The top margin of the PDF in inches (e.g., 0.5) default 0.4
`marginRight`OptionalPremium	number	The right margin of the PDF in inches (e.g., 0.5) default 0.4
`marginBottom`OptionalPremium	number	The bottom margin of the PDF in inches (e.g., 0.5) default 0.4
`marginLeft`OptionalPremium	number	The left margin of the PDF in inches (e.g., 0.5) default 0.4
`landscape`OptionalPremium	boolean	Set to true for landscape orientation

What the model gets back

The result carries a structuredContent object matching the tool's declared outputSchema, so a client reads fields without parsing prose. status is "ok" and error is null on success; a null field means the value was not available for that input, not that the call failed.

Response fields

Paths are relative to data. Premium fields are absent rather than zeroed on plans that do not include them, so check for presence instead of comparing to 0.

Field	Type	Example	Description
`marginLeft`	string	`0.4in`	Left margin of the PDF in inches
`marginRight`	string	`0.4in`	Right margin of the PDF in inches
`marginTop`	string	`0.4in`	Top margin of the PDF in inches
`marginBottom`	string	`0.4in`	Bottom margin of the PDF in inches
`landscape`	boolean	`false`	Whether the PDF is in landscape orientation
`pdfName`	string	`c064eacc-c29f-43a1-8375-a4b2562ea9d8.pdf`	Unique identifier filename for the generated PDF
`expires`	number	`1766096665366`	Unix timestamp when the PDF download URL expires
`downloadURL`	string	https://storage.googleapis.com/apiverve-helpers.appspot.com/htmltopdf/c064eacc-c29f-43a1-8375-a4b2562ea9d8.pdf?GoogleAccessId=1089020767582-compute%40developer.gserviceaccount.com&Expires=1766096665&Signature=R%2Ft%2FXcR%2B8bXzCi5ztc01YeE%2Bbn1ZR%2BCyeoqgHpSB1z0LO3SetOSoWYVoon5IG4vUU9W30Rmw6owErorZal%2FHdgpmcPAYx3eTx5dPaD45tFSCgIfpRloi0DBLse%2Fzy4sb0k3XgweiHZUdZu3jKMi1HVDJa2j2ervAFfwDfxGHUDXH5wwFKqnv%2BIw%2Fu7MBsKMDCNMWYESE7Aicz6eL0Lxz8P6oazJX0akKlLDhkgKiIqF3VtjGIh36RzK4WGBpU36JFZ7SCZZGHNiHyt3%2FBdyjPRA8N1fky%2Bv%2BjR%2BTTlO9BpWcjImNJM6nvVfmICEfcbLqL2MvVldfPAFKyEv2zCrCLA%3D%3D	Signed URL to download the generated PDF file

Failure modes

Errors come back as tool errors carrying a sentence the model can act on, not a bare status code. Error handling covers the full list.

Status	What it means
`400` / `422`	The arguments did not validate. The message names the offending one.
`401`	The OAuth session is invalid or expired — reconnect the server.
`403`	Blocked by a key restriction or an IP allow-list. Never a bad identity.
`404`	This skill is not part of VerveKit. Check the catalog.
`429`	Out of credits, or a brief rate limit. The message tells them apart.

A call costs 20 credits each time the tool actually runs; a model that reasons about the tool without calling it costs nothing.
