Gravatar Lookup Skill

Overview

A Gravatar lookup by email, for prefilling profiles, showing comment avatars and enriching signups. The address is lowercased, trimmed and hashed with SHA-256, the identifier Gravatar uses, and the public profile is read live from Gravatar: display name, username, bio, location, company, job title, pronouns, avatar URL and alt text on every plan. Paid plans add the accounts the owner has verified on Gravatar, including ones hidden from their profile page (flagged hidden), and whether the email has its own uploaded avatar or only Gravatar's default image, a quick signal of a real, maintained identity. An email with no Gravatar profile returns a 404 rather than an empty profile.

The tool

Once your client is connected to the VerveKit server, this appears in its tool list as GravatarLookupSkill. 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.

{
  "name": "GravatarLookupSkill",
  "arguments": {
    "email": "[email protected]"
  }
}

You do not name the tool yourself; the model picks it. Asking about [email protected] in the terms this skill covers is enough for it to reach for GravatarLookupSkill 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.

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.

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.

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

Onboarding Form Prefill

When new members sign up, web apps pull display names, job titles, and avatars to prefill account profile pages.

CRM Contact Enrichment

Sales teams populate lead records with company names, bios, and locations pulled directly from an inbound contact's work email.
