What the Customjs integration exposes
CustomJS is a code-first automation platform that enables seamless integration of custom JavaScript logic into various systems and technologies, allowing users to extend applications by writing functions for tasks like sending emails, generating PDFs, or updating CRM data fields.
One connection, many teammates
Connect Customjs once, then decide which teammates can use it for threads, automations, skills, and coding work.
Representative actions

FAQ
Questions people ask before connecting Customjs
Can Claude Code use Customjs?
Yes. Type lets an AI teammate use connected Customjs actions from a governed workspace context, so Claude Code work can reference the app without copying credentials into a local prompt.
Can Codex work with Customjs through Type?
Yes. Codex can collaborate through Type with app context, skills, and approved actions. The Customjs catalog entry includes public integration details and example capabilities where available.
Is this the same as a Customjs MCP server?
Type exposes connected app capabilities to AI teammates and coding agents through Type's integration layer. Teams use it when they want shared app access, human review, and teammate-level permissions around agent work.
