How to use it with AI
How lemlist connects to each AI platform: native connector or MCP, API through code the agent writes, browser control, or file upload.
| Platform | MCP / connector | API (agent-written code) | Browser | Upload / export |
|---|---|---|---|---|
| Claude (incl. Claude Code) | Confirmed Setup steps in lemlist's help center lemlist docs ↗Claude (incl. Claude Code) MCP docs ↗ | Confirmed Claude (incl. Claude Code) can run code; lemlist publishes an API. lemlist API ↗Claude (incl.

| Google Antigravity | Not documented lemlist has an official MCP server and Google Antigravity supports MCP, but lemlist's docs don't name this pairing. Auth setup may differ. lemlist MCP docs ↗Google Antigravity MCP docs ↗ | Confirmed Google Antigravity can run code; lemlist publishes an API. lemlist API ↗Google Antigravity docs ↗ | Confirmed Browser subagent via /browser, documented as an Antigravity App feature; the IDE has separate browser docs Google Antigravity browser docs ↗ | Confirmed Export from lemlist, then works on local projects and worktrees Google Antigravity docs ↗ |
lemlist's docs also name: ChatGPT.
Confirmed means both the tool's and the platform's official docs describe that route (links in the cell); IonBin has not tested every pairing. Not documented means it may work, but no official docs describe that route end to end. Checked Oct 17, 2026.
