CaffeineLabs publishes a large suite of extension-* capabilities for an agent platform, plus connector and Motoko (Internet Computer language) series.

Stripe, object storage, authorization, HTTP outcalls, and X posting round out the platform-integration surface, with Google Mail and Google Calendar connectors in the 7-10K range.

Integration with CorpusIQ¶

CorpusIQ is the connector layer that lets AI assistants read the systems a business already runs on - accounting, payments, CRM, email, files and analytics - and answer with the source named. It is read-only by design: it retrieves data and never writes to, or acts in, a connected system, which is what makes it safe to point at live accounts.

This page is part of the CorpusIQ directory, the reference we maintain for the MCP server and agent-skill ecosystem. Run alongside CorpusIQ, a third-party server like this one can be combined with a company's own business data in a single answer.

Limitations / Verification¶

The extension series targets a specific platform runtime, not raw Claude Code or Hermes sessions - treat it as a pattern reference plus capability set for that platform
Motoko skills are for Internet Computer canister development, niche outside ICP work

npx skills add caffeinelabs/skills --skill extension-email-verification   # verify install works
