Overview

Metadata Extractor works by parsing the HTML content of a web page to extract the metadata. It returns the meta title, meta description, and more in a structured format.

Live Test Webpage Metadata Grounding Data Source →

The tool

Once your client is connected to the VerveContext server, this appears in its tool list as WebpageMetadataGroundingData. 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": "WebpageMetadataGroundingData",
  "arguments": {
    "url": "https://www.wikipedia.org"
  }
}

You do not name the tool yourself; the model picks it. Asking about https://www.wikipedia.org in the terms this source covers is enough for it to reach for WebpageMetadataGroundingData on its own — naming it explicitly also works, and is the way to force the call.

Connecting

One server URL covers every source 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": {
    "vervecontext": {
      "url": "https://api.vervecontext.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.

ArgumentTypeDescription
urlRequiredstringThe URL of the web page to extract metadata from
url

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.

Why ground on it

A model can produce something that looks like this answer from its training data, and be confidently out of date or simply wrong. This source returns the current value in a shape you can check, which is the difference between an answer you can cite and one you have to hedge.

Point an evaluation at requestUrl: it is the field most worth pinning a claim to, and it is either present and current or absent — never plausibly invented.

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.

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

A call costs 2 credits each time the tool actually runs; a model that reasons about the tool without calling it costs nothing.

Use cases

Social Link Previews
Chat applications fetch page title and meta description tags from shared links to display inline reading snippets in conversation feeds.
Bookmark Library Archiving
When archiving external resources, digital asset management platforms capture the page author, description, and keywords to catalog source references.
Search Crawl Auditing
Flag indexing barriers across client domains by evaluating robots tags, character encoding, and viewport settings extracted during scheduled crawls.
Link Redirect Verification
To detect outdated redirects, publishing platforms compare the original submitted URL against the resolved destination address and page title.
