lemlist
Overview
lemlist is a sales engagement platform for cold outreach: it finds leads in its people and companies databases, enriches them with verified emails and phone numbers, runs multichannel campaigns across email, LinkedIn, phone and WhatsApp, and keeps contacts and replies in its own CRM and inbox. The MCP server and the `lemlist` CLI sign in with OAuth; the MCP server also accepts an API key in an `X-API-Key` header, and `?bucket=` narrows the tools it advertises. The CLI's `lemlist api <METHOD> <path>` calls any endpoint of the REST API. The REST API uses HTTP Basic auth with an empty username and the API key as the password, so `LEMLIST_API_KEY` must hold the base64 encoding of `:` followed by the key. Each key may send 20 requests every 2 seconds, and enrichment spends the team's credits.
