Set up in minutes

The open button drops you into a guided setup. It asks exactly this, nothing else:
  1. Choose where it runs

    On your computer through your own Codex, or hosted in the cloud. The rest of setup adapts to your choice:

  2. Pick what it can do in Open Policy Agent

    A preset of real Open Policy Agent operations. Each one becomes a tool the agent can call, and it can't touch anything outside the list.

  3. Connect Open Policy Agent

    One sign-in. The agent acts through your account, scoped to the operations you picked.

  4. 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

Pick the operations you want and each becomes a tool the agent can call directly while it works.

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
