## MCP tools (5)

### `search_leads` (~398 tokens)

Search for companies and business contacts in real time by industry, city, and other filters. Returns a ready-to-use list of leads (name, address, phone, website, rating, and email where available). Use this whenever the user asks to find, list, or collect businesses/companies for sales, outreach, or research.

Input parameters:

- `city` (string): City or region to search in, e.g. "Berlin" or "Austin, TX".
- `has_website` (boolean): Only return businesses that have a website.
- `industry` (string): Industry filter. One of the predefined categories.
- `lang` (string): Result language as a BCP-47 tag, e.g. "en" or "pt-BR".
- `limit` (integer): Max number of results to return (1-20). Defaults to a server-side value if omitted.
- `list_id` (string): Existing saved-list ID to append results to.
- `list_name` (string): Name of a saved list to find-or-create and append results to.
- `min_rating` (number): Minimum rating (0-5) a business must have to be included.
- `open_now` (boolean): Only return businesses that are currently open.
- `page_token` (string): Pagination token returned by a previous call, to fetch the next page of results.
- `price_level` (string): Filter by price level.
- `q` (string): Free-text search query, e.g. "construction companies in Munich". Optional if industry+city are given.
- `radius_km` (number): Search radius in kilometers around the city center.
- `rank_by` (string): How to sort results.
- `save_to_list` (boolean): If true, also save the results into a B2BLeads saved list (requires list_id or list_name).
- `verified_only` (boolean): Only return businesses with a verified listing.

### `list_industries` (~30 tokens)

List the predefined industry categories that can be used as the `industry` filter in search_leads.

### `list_saved_lists` (~46 tokens)

List all of the user's saved lead lists (read-only), each with its full set of saved leads. Use this when the user asks what they've already saved, or which lists exist.

### `get_saved_list` (~55 tokens)

Get one saved lead list by ID, including its full set of saved leads (read-only).

Input parameters:

- `list_id` (string, required): The saved list's ID, from list_saved_lists or a search_leads save_to_list response.

### `find_email` (~101 tokens)

Look up a best-effort contact email for a single business website (checks the homepage and common contact pages). Use this for one specific website, e.g. from a saved list or CSV, rather than re-running search_leads. May return a null email if none could be found; this tool never fabricates an address.

Input parameters:

- `website` (string, required): The business website URL to look up a contact email for, e.g. "https://example.com".
