This guide walks you through connecting lemlist to your AI assistant via MCP, then shows you exactly what you can do with it. Setup takes about 2 minutes. The real value is in what comes after.

lemlist's MCP server supports two ways to authenticate.

OAuth (recommended) OAuth is the simpler path. Your AI client handles the entire authentication process automatically: it opens a browser window, you log in and grant access to your lemlist team, and that's it. No key management, no copy-pasting credentials.

API key If your client doesn't support OAuth flows, or you prefer to manage credentials manually, you can authenticate with a lemlist API key. Best for Cursor, CI environments, or custom integrations.

For the full step-by-step setup guide (OAuth + API key for Claude Desktop, Claude Code, and Cursor), see our How to Connect Lemlist to an LLM Using MCP guide.

The fastest way to get started:

Ask your AI assistant directly: "What lemlist operations can you perform?" — it will return the most current list. Typical operations include:

Connecting lemlist to an LLM isn't just about convenience — it changes the way you work. Below are concrete jobs to be done, each showing a real scenario, who benefits, and what you'd actually say to your AI assistant.

Who it's for: SDRs and founders who need to launch fast without toggling between tabs.

What happens: Your AI creates the campaign, writes all four emails with proper variables and timing, and sets it up in your lemlist account. You review, tweak if needed, and launch.

Who it's for: Sales managers and RevOps leads who want a snapshot before their first meeting.

What happens: The AI pulls stats from every active campaign, flags underperformers, and suggests what to fix — subject lines, send times, or lead quality issues.

Who it's for: Growth marketers and SDRs who spend hours manually building lead lists.

What happens: The AI searches lemleads with your criteria, deduplicates against existing contacts, and imports qualified leads directly into the right campaign.

Who it's for: Anyone running campaigns that aren't converting and not sure where the bottleneck is.

What happens: The AI analyzes the full funnel — open rates, click rates, reply rates, step-by-step drop-off — and gives you specific, actionable recommendations: rewrite step 2's subject line, shorten step 3, adjust follow-up timing.

Who it's for: SDRs and copywriters who want to A/B test new angles without starting from scratch.

What happens: The AI reads your existing sequence, rewrites each step using Problem-Agitate-Solution, preserves your personalization variables, and updates the campaign.

Who it's for: Sales teams targeting users of a competing product.

What happens: The AI sources leads matching the technographic criteria, builds a targeted campaign with competitive positioning, and sets up the sequence ready for your review.

Who it's for: RevOps and sales leaders who need to report on outbound performance without building dashboards.

What happens: The AI aggregates data across all campaigns, computes week-over-week deltas, and delivers a clean summary you can paste into Slack or share with your team.

Who it's for: Anyone who wants to go beyond {{firstName}} without spending hours on research.

What happens: The AI enriches each lead with context, writes a unique icebreaker per contact, and updates the campaign variables — turning a generic blast into hyper-personalized outreach.

Once the MCP is connected, you can set up a dedicated lemlist agent command inside Claude Code. This gives you a pre-configured expert assistant that knows how to audit campaigns, source leads, and write sequences without re-explaining context every time.
