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 Postmark

Run Codex as a hosted agent in NoClick with Postmark wired into its tools handle. It can use Postmark directly while it works. No glue code, nothing to install. Click below to open a ready-to-run agent and connect your account.

Set up in minutes

The open button drops you into a guided setup. It asks exactly this, nothing else:

Choose where it runs
On your computer through your own Codex, or hosted in the cloud. The rest of setup adapts to your choice:
Pick what it can do in Postmark
A preset of real Postmark operations. Each one becomes a tool the agent can call, and it can't touch anything outside the list.
Connect Postmark
One sign-in. The agent acts through your account, scoped to the operations you picked.
Add your personal MCP link
The last step mints a private MCP URL for this agent and walks you through exactly this, with your real link filled in. The page flips to Connected the moment your Codex first calls in. Codex connects when a session starts — run codex, or restart a running one (in the Codex app, Restart).
Run this in your terminal. The Codex app shares its config, so it gets the server too
$codex mcp add noclick --url https://mcp.noclick.app/s/<your-link>
<your-link> is your personal server URL — setup mints it for you.

Tools Codex gets

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
