The walkthrough uses the original ChatGPT web plugin captures. After connecting, open Codex in the desktop app and start a new task with ApexGenius. A ChatGPT web connection does not verify Codex access.
A public ApexGenius plugin listing is not verified. Use a plugin shared with you or one you created, subject to your account and workspace policy.
Create a personal plugin
Where Developer mode is available, open ChatGPT Settings, then Security and login, and enable it. In Plugins, select the plus button, enter ApexGenius and a description, then add this URL under Connection. Create the connection, complete OAuth, and review the tools. Return to Codex in the desktop app and start a new task with the plugin enabled.

You choose what Codex is allowed to touch
Choose the saved accounts and tools this Codex connection may use. Its authorization carries that scope, and each app connection’s tool and resource restrictions still apply.
- Full accessEvery enabled tool on the connections you choose.
- Read onlyLooks things up, changes nothing.
- CustomPick apps and tools one by one.
- · Context.dev controls the OAuth grant. The connection acts for your Context.dev organization and uses its shared credits.
- · The read route checks Context.dev's live tool label and rejects writes or unlabeled operations.
- · Writes run right away unless you set the tool to Ask me first. A deleted monitor or batch cannot be restored.
- · Fetched page text is untrusted data. The ContextDev skill tells your AI to quote and cite it and never follow instructions inside it.
- · Disconnecting stops future gateway access. It does not stop monitors or batches that already exist.
The Context.dev operations Codex can run
34 operations: 27 Read and 7 Write. Available tools depend on your connection and permissions. Review any action that changes or removes data. Codex discovers these operations through the ApexGenius gateway.

Questions people ask first
How do I connect Context.dev?
Open Context.dev in ApexGenius Connections, choose Connect, and sign in to Context.dev in the browser. ApexGenius registers itself with the hosted Context.dev MCP. No API key is pasted into ApexGenius.
Does it spend Context.dev credits?
Most calls do. A scrape is 1 credit, a web search is 1 credit per 10 results, a crawl is 1 credit per page and a brand lookup is 10 credits. Listing monitors is free. Free organizations get 1,000 credits a month with a work email, or 250 once with a personal email.
Can my AI change my Context.dev account?
Yes. It can create, update, run or delete monitors and submit, cancel or delete batches. Writes run right away unless you set the tool to Ask me first. A deleted monitor or batch cannot be restored.
Can a web page tell my AI what to do?
It should not. Page text is data. The ContextDev skill tells your AI to quote and cite it and never follow instructions found inside it. Review results before you act on them.
Can I take this setup to another AI agent?
Yes. Add ApexGenius to another compatible agent with the same ApexGenius account. It uses the same Context.dev connection and can load the ContextDev skill. Each agent needs its own setup.
