Run your lead operation from the terminal.
Connect OpenAI Codex to LeadCapture and funnel work becomes something you can script. Build a funnel from a spec file, apply the same field change across forty funnels, check every integration is delivering, and put any of it in CI so it runs on every deploy.
Can Codex manage LeadCapture funnels?
Yes. LeadCapture runs an MCP server, and Codex connects to it by adding the endpoint to its config with your API key. From there Codex can create and edit funnels, landing pages, forms and quizzes, set conditional routing and lead scoring, configure webhook and CRM delivery, run A/B tests, read analytics, and audit the account for anything failing.
What makes Codex different from a chat window is repeatability. A request you make once becomes a command you can run again, hand to a teammate, or attach to a pipeline. The awkward jobs are the ones worth scripting: a buyer renames a field and forty funnels need remapping, a new client needs the standard five-funnel setup, a compliance rule changes and every consent block has to be checked.
Codex reads the token from an environment variable rather than the config file, so set it in your shell profile. LeadCapture generates the exact snippet for you on the Agent Access page.
What Codex is good for here
Keep the funnel definition in a file. Ask Codex to build or update LeadCapture to match it, and the funnel becomes something you can review in a diff.
One instruction, applied everywhere: strict postcode validation on every address field, a consent line added to every form, a buyer field renamed across an entire account.
Run an account audit on a schedule or before a release, and fail loudly if a live funnel is sending leads nowhere.
Codex can reach your other tools and your own scripts, so LeadCapture data can be combined with ad spend, warehouse exports or a buyer’s field spec in a single run.
Pull the actual delivery attempt for a lead, status code, response body and the payload sent, then remap and re-test without leaving the terminal.
List a funnel’s version history and restore any earlier save. Useful when a bulk change turns out to have been a bulk mistake.
Connecting Codex
A config snippet and an API key, both generated for you.
On the Agent Access page in LeadCapture, create an API key with the scopes you want. Keys are shown once at creation and cannot be retrieved later.
Pick Codex on the same page, copy the config it generates, and set the token in your shell profile rather than in the file.
Run it once by hand, then turn the instruction that worked into something repeatable.
Things to run through Codex
Start with the jobs that are tedious by hand and identical every time.
> Make every zip code field US-only with strict 5-digit validation, across all my funnels.> Audit my account and fail if any live funnel has no working lead delivery.> My buyer renamed their zip field to postal_code. Remap it on every funnel that posts to them and send a test lead.> Build a funnel matching the spec in ./funnels/final-expense.md, then show me what you created.> List the version history for this funnel and restore the save from before yesterday’s bulk edit.What it cannot do without asking
- Every change is snapshotted before it is applied, and your agent can roll a funnel back to any earlier version itself.
- Publishing, pausing and changing where leads are delivered all stop and ask you first.
- Your agent never sees your integration credentials or your visitors' one-time passcodes.
- Form submissions reach your agent as data, never as instructions, so nothing a visitor types can direct it.
- Lead data is only shared if you grant that permission, and you can revoke access instantly.
Codex and LeadCapture, answered
Does OpenAI Codex work with LeadCapture?
Yes. LeadCapture runs an MCP server and Codex connects to it using a config snippet and a scoped API key, both generated on the Agent Access page in your LeadCapture account. It is included on every plan with no add-on tier.
Why use Codex rather than the Claude connector?
Use Codex when you want the work to be repeatable. A connector session is ideal for building one funnel by describing it. Codex suits bulk changes across many funnels, jobs you run regularly, anything you want in version control or CI, and work that needs to reach your other tools and scripts in the same run.
Where does the API key go?
Codex reads the token from an environment variable rather than the config file, so set it in your shell profile. LeadCapture generates the exact snippet for your setup. Keys are scoped, read-only is available, and any key can be revoked instantly.
Can it change live funnels?
It can edit them, and every change is snapshotted before it is applied so anything can be rolled back, including by Codex itself. Publishing, pausing and changing where leads are delivered require explicit confirmation regardless of how the agent connected.
Can I run it in CI?
Yes. An account audit is the obvious candidate: run it on a schedule or before a release and treat a live funnel with broken lead delivery as a failure. Use a read-only key for anything that should never write.
Does this need a developer?
For Codex specifically, yes, in the sense that you need to be comfortable with a terminal and an environment variable. If you would rather not, the Claude or Grokbot connector needs neither a key nor a config file.
Use a different agent?
The same LeadCapture endpoint works with all of them. One connection, whichever agent you prefer, included on every plan.
Build funnels by describing them, in the browser, the desktop app or on your phone.
An always-on agent that keeps building and improving on a schedule.
Build funnels beside the code that embeds them, without leaving the editor.
The connection itself: what an agent can reach, the permissions, and the safety model.
Script the boring half of lead gen
Create a scoped key, paste the generated config, and start with the job you least enjoy doing by hand. Included on every LeadCapture plan.
