Why connect Attio to Claude Code?

Records in Attio usually arrive from your product: a signup webhook, a form, an enrichment job. When attributes come in empty, the cause is in that code. Claude Code reads it, and with Lemonado it can check the records that actually landed in Attio.

  • All your Attio data

    Companies and people, with enriched attributes, ready to ask about.

  • Always today's numbers

    Lists and the records in each, synced from Attio automatically, so answers use today's numbers.

  • Connect all your tools

    Questions like "Do target accounts see our ads?" use Attio and Pipedrive, HubSpot at once.

    Ask Claude Code about Attio

    Ask a question about the accounts your connection can reach. Claude Code can also write the numbers into a file or a script for you. Try "Our signup handler in api/signup.ts creates people and companies in Attio. Compare what it sends with the attributes filled on people created this month." Or ask: "Export accounts with usage" or "Find duplicate companies"

Good to know

  • The command uses Claude Code's default local scope. Use --scope user to share the server across projects.

What can Claude Code do with Attio?

Claude Code queries your Attio data while it works in your repo: it saves data as files, checks tracking against code and runs headless with claude -p.

Claude Code logoClaude Code

Our signup handler in api/signup.ts creates people and companies in Attio. Compare what it sends with the attributes filled on people created this month.

The handler sends utm_source as "source", but the Attio attribute is called "lead_source". 380 people this month have it empty.
