Find a mobile phone number

You are wiring up the superagnt "Lead APIs" API to use this endpoint: Find a mobile phone number.

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_find_mobile
   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/find-mobile
     Header: Authorization: Bearer <YOUR_AGNTDATA_API_KEY>
   Required parameters:
    - identifiers (object, required) — Unique handles used to resolve the person. Provide AT LEAST ONE of `email` or `linkedin_url`. Name + company are NOT accepted — call `/people/email-finder` first if that is all you have. A lookup that matches nothing is not an error: it returns `mobile: null` with `meta.empty: true` and is not charged. Retrying the same input will not find it.
   Optional parameters:
    - max_cost_cents (number, optional)

3. COST & KEY. This endpoint is metered — pricing varies by request, from $0.12 per call. Only successful calls are charged.

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