Overview

Lusha is a B2B data platform for prospecting and enrichment: verified emails, direct and mobile phone numbers, company firmographics, and signals such as job changes, promotions, hiring surges and funding news. Its MCP server finds and enriches contacts and companies, searches by ideal customer profile, finds lookalikes and returns signals and scored recommendations. The MCP server signs in with OAuth; a client without OAuth can send a Lusha API key in the `x-api-key` header instead. The REST API (version 3, under `https://api.lusha.com/v3/`) takes the key in an `api_key` header. Searches return previews without emails or phones. Credits are charged per search result, per revealed email or phone and per matched signal, and failed lookups are not charged.
