TerminalsCodex

Refactor the pages that earn, not the ones that are easy

OpenAI's terminal agent, reading your traffic while it edits. One MCP server, five read-only tools, and a key that opens exactly one site.

Why Codex

How to connect

Three steps, and Codex can read your site

A key is issued per site and cannot be talked into reading another one, so handing one to an agent hands it exactly what you meant.

Issue a site key
In Alexander: Settings, Integrations, MCP server. Keys look like alx_ and a fresh one is shown once, so paste it straight into the config below.
alx_live_7f2c…
2
In ~/.codex/config.toml, add the server
Paste this into ~/.codex/config.toml.
~/.codex/config.toml
```
[mcp_servers.alexander]
url = "https://mcp.alxndr.ai/mcp"
bearer_token_env_var = "ALEXANDER_KEY"
```
Codex reads TOML, and takes the key from the environment rather than the file: export ALEXANDER_KEY before you start it.

Ask it something you already know
The fastest way to tell a working connection from a confident guess is to ask for a number you can check.

What you can ask

Questions, not queries

Type it the way you would say it. Codex picks the tool, Alexander returns the rows, and the answer arrives with the numbers in it.

Before I touch this template, what depends on it?

get_pages· Pages

It renders /pricing and /pricing/teams: 2,777 and 412 views, €3,457 between them last month.

Rank the routes by revenue so I can start at the top.

get_pages· Pages

/pricing €3,457, /checkout €2,904, /docs €118, and eleven routes at zero.

Did anything regress after the deploy?

get_overview· Headline numbers

Bounce rate on /pricing moved 41% to 44% and the funnel's first step is down 6%. Nothing else changed.

Example answers, shaped exactly as the tools return them, on a demo shop rather than a real customer's books.

The surface

Five tools. That is the whole of it.

Every client on this site reaches the same five, and not one of them can write. There is no sixth tool, no settings tool and no way to reach a site the key was not issued for.

Headline numbers

get_overview

Visitors, pageviews, revenue, conversions, bounce rate and who is on the site this second.

Sources

get_sources

Where visitors came from, ranked by revenue per visitor rather than by volume.

Pages

get_pages

The most viewed pages, each with the revenue of the sessions that saw it.

Funnel

get_funnel

Every step with the drop-off to the next, so the leak has a name.

Insights

get_insights

The written findings: what changed, the evidence, the suggested action, a confidence score.
