Which Gmail and Linear operations are available to it?

Only the ones you allowlist, like searching mail or creating a Linear issue. Operations you omit cannot be called by the agent.

Do I have to self-host the harness?

No. NoClick runs Codex for you and connects Gmail and Linear as tools you authorize once.

Will it reply to people without my say-so?

Only if you allowlist a reply or send operation. Leave it off and the agent stops at creating the issue and reports back.

How does Codex get access to my apps?

You connect an integration to the agent's tools handle and select which operations to expose. Codex then calls those operations as tools, authenticated with the credentials you connect in NoClick.

Is this the same Codex CLI?

Yes. NoClick runs the Codex harness for you and adds your connected apps as tools. You do not have to install or manage anything locally.

Can I trigger a Codex agent automatically?

Yes. Because it runs hosted, you can start it from a schedule, a webhook, or another app event, not just by hand.

Which apps can I connect?

Any of NoClick’s tool-provider integrations, from Slack and Linear to GitHub, Notion, Google Sheets, Postgres, and dozens more.

Codex

Connect Codex to Gmail and Linear

With Gmail and Linear connected, Codex can move a request from your inbox straight into your team's backlog. It reads and searches mail, files a Linear issue with the right team and labels, and replies to the sender to acknowledge it. The two tools let the agent own the handoff from email to a tracked, prioritized ticket.

About Codex

Codex is OpenAI's command-line coding agent. NoClick runs it as a hosted agent and lets you connect your apps to it as tools, turning it from a coding assistant into an operator that can act across your systems. Connect an integration to the agent and Codex can query, create, and update records in that app directly. You keep the Codex experience and give it real reach into the tools your team already uses.

Fast, capable code generation and editing

Good at well-scoped, concrete tasks

Strong at API and data manipulation

Familiar to teams already on OpenAI tooling
