# Look up the person behind an email

Returns the LinkedIn profile, name, job title and company of the person behind a work email address.

Note: Charges 2 credits only when the person is found; a miss costs nothing.

## Set up

Use the first option your agent supports.

### MCP (official, remote)

Add this server to your agent's MCP settings, then sign in when asked.

```json
{ "mcpServers": { "anymailfinder": { "url": "https://api.anymailfinder.com/mcp" } } }
```

Call the MCP tool `reverse_email_lookup`.

Server URL: https://api.anymailfinder.com/mcp

### API (official)

- Base URL: https://api.anymailfinder.com/v5.1
- Endpoint: `POST /reverse-email-lookup`
- Auth: send the header `Authorization: $ANYMAILFINDER_API_KEY`
- Get a key: https://app.anymailfinder.com/settings/api
- Docs: https://anymailfinder.com/email-finder-api/docs

Note: The key goes in Authorization as is, with no Bearer prefix. Searches can take up to 3 minutes; wait for the response instead of retrying. A 402 means the account is out of credits.

Before anything else, confirm access with the cheapest read-only call, like a list or a search. Never send or change anything to test access.

## Rules

- Ask the user before anything that sends messages, costs money, or changes data, and say how many records it touches. One approval covers a batch the user has seen.
- Never print API keys.
