Find a person's professional email

You are wiring up the superagnt "Lead APIs" API to use this endpoint: Find a person's professional email.

1. CONNECT over MCP (preferred). No token to paste either way.
   On Claude (claude.ai, the desktop app, or Claude Code signed in with a Claude
   account), the server is a connector: give the user this link, they click Add
   and approve:
     https://claude.ai/customize/connectors/yours?modal=add-custom-connector&connectorName=superagnt&connectorUrl=https%3A%2F%2Fmcp.superagnt.com%2Fmcp&open_in_browser=1
   Any other MCP client (or Claude Code signed in with an API key): add the server
   and let the client run the browser sign-in:
     claude mcp add --scope user --transport http superagnt https://mcp.superagnt.com/mcp
     claude mcp login superagnt
   MCP endpoint: https://mcp.superagnt.com/mcp
   After connecting, the tool you want is named exactly:
     data_agnt_people_email_finder
   Call agnt_tools_search or agnt_tools_list_enabled to confirm it is available.

2. REST fallback (if you are not using MCP):
     POST https://api.superagnt.com/people/email-finder
     Header: Authorization: Bearer <YOUR_AGNTDATA_API_KEY>
   Required parameters:
    - (none)
   Optional parameters:
    - first_name (string, optional) — Person's first name. Pair with `last_name` (or use `full_name` instead).
    - last_name (string, optional) — Person's last name. Pair with `first_name`.
    - full_name (string, optional) — Person's full name — alternative to `first_name` + `last_name`.
    - domain (string, optional) — Company root domain (e.g. "tesla.com"). Strongest company signal.
    - company (string, optional) — Company name (alias of `company_name`). Use when domain is unknown.
    - company_name (string, optional) — Company name (alias of `company`).
    - max_cost_cents (number, optional)

3. COST & KEY. This endpoint is metered — pricing varies by request, from $0.02 per call. Only successful calls are charged.

4. TEST. Connect the server (or set the key), discover the tool
   (data_agnt_people_email_finder), run one minimal call with just the required parameters,
   and report back the shape of the JSON response (top-level fields).

Identifier fields are at the TOP LEVEL of the body (NOT inside an `identifiers` object): `first_name` + `last_name` (or `full_name`) plus `domain` (or `company` / `company_name`). LinkedIn URL/handle is not currently supported here — if that is all you have, call `/people/enrich` first with `identifiers.linkedin_url` to resolve name + domain, then call this endpoint. agntdata waterfalls cheapest-first across providers until an email is returned (or your `max_cost_cents` budget is exhausted). If you already know the email and want to look up other fields, use `/people/enrich` instead with `identifiers.email`.",
