New to the protocol? Start with what an MCP server is.
What is the Lusha MCP
The Lusha MCP server is Lusha’s official implementation of the Model Context Protocol, the open standard that lets AI applications talk to external systems. It connects an assistant to Lusha’s sales intelligence database of 300M+ verified contacts.
So instead of exporting lists, you ask for the people and accounts you want and Lusha returns verified, enriched data in the conversation, with the compliance posture Lusha is known for.
It works with Claude, ChatGPT (OpenAI), and any other assistant or LLM that supports the Model Context Protocol.
What the Lusha MCP lets you do
The server ships 17 tools across prospecting and intelligence. Grouped:
- Search and enrich: search contacts and companies, then enrich them with verified emails, direct and mobile numbers.
- Buyer signals: find and filter the contacts and companies showing intent right now.
- Lookalikes: surface companies and contacts that resemble your best accounts.
- Usage: check your account usage and remaining credits.
A few examples:
- “Find RevOps leaders at Series B SaaS companies in EMEA and enrich their direct numbers.”
- “Which of my target accounts are showing buyer signals this week?”
- “Give me 20 companies that look like my top three customers.”
How to install the Lusha MCP
Setup runs over your Lusha API key.
- Connect your account: point your MCP client at
https://mcp.lusha.comand authenticate with your Lusha API key (thex-api-keyheader). See the Lusha MCP documentation. - Use it in ChatGPT and Codex too: OpenAI supports MCP, so you can add this server in ChatGPT through connectors or in OpenAI Codex.

Concrete use cases: from verified data to outreach
Lusha is the data layer. La Growth Machine runs the outreach. Connect both to the assistant and verified contacts and intent flow straight into a campaign.
Research an account before a call
What it produces
A quick, verified brief on an account: who the decision makers are, their direct numbers, and the firmographics, pulled in seconds so you walk in prepared.
Prompts to try:
- Profile this account: decision makers, direct numbers, headcount, and recent moves.
- Who should I talk to first, and how do I reach them?
Reach in-market accounts first
What it produces
A prioritized, enriched list of accounts showing intent, and the multichannel sequence to work them. Buyer signals decide who you contact first.
Example output of the skill that writes the sequence:
Cold outbound to Heads of Sales at French B2B SaaS startups. Lead angle: “your reps spend 40% of the week on manual prospecting.”
Prompts to try:
- Pull the accounts in my market showing buyer signals, enrich the right contacts, and queue them to a La Growth Machine sequence.
- Prioritize the list by signal strength.
See the Multichannel Campaign Builder skill.
Expand with lookalikes
What it produces
A fresh set of accounts that resemble your best customers, enriched and ready to sequence, so you grow the pipeline without starting from a blank search.
Prompts to try:
- Find lookalikes of my top closed-won accounts and enrich the buying committee.
- Drop the new contacts into a dedicated audience.
⚠️ La Growth Machine does not have a native Lusha integration (yet). You connect the two by orchestrating both MCP servers from the assistant, or through an automation layer like Zapier, n8n, or Make. See the La Growth Machine integrations. Lusha is a verified-data provider with built-in buyer signals; if you would rather orchestrate enrichment across many providers, see the Clay MCP.
Tips and security
The Lusha MCP reaches contact data and runs on credits, so be deliberate.
- Watch your credits: enrichment draws on your Lusha plan, so check usage before a large pull.
- Scope the search: tighten filters before enriching, so you spend credits on the right contacts.
- Mind the data: Lusha is GDPR, CCPA, and SOC 2 compliant, but you are still the one sending, so keep your outreach consent-aware.
- Use trusted connectors: Lusha’s connector is official, built by Lusha.
