Our company id. Send it to the contact filter in company_ids.
Overview
LeadMCP is a contact-data API and an MCP server for AI agents. An agent sends structured filters and gets a count, a page of contact rows, a file, or an enrichment answer.
Our data, licensed from multiple sources.
The store holds hundreds of millions of professionals and the companies they work for. We publish no row totals. To size an audience, run a count against your own filters. A count is free.
The REST API and the MCP server sit on the same routes. Your code calls the API. Your agent calls the MCP server and gets the same answers.
A session runs in one order. Count the audience first, because a count is free. Then search to look at a sample of the rows, or export to deliver the whole list. Enrich when you already hold a work email, phone number or LinkedIn URL.
To collect a list, start an export. Do not page a search to build one.
The paid plan costs $500 a month and has unlimited contact credits, under the Fair Usage Policy. One contact credit is one contact delivered. Premium units (engagers, verified emails) draw on a separate monthly premium credits allowance. Stored contact delivery uses contact credits. Phones come free in every row where available.
Company fields
Company facts describe the current employer. The Company API serves the full company record: POST /companies/search finds companies, POST /companies/lookup reads them by id, domain or LinkedIn URL, and company_ids on the contact filter finds their people.
