/llms.txt and /llms-full.txt
A structured index of the whole site with one line per page, and a second file with every page inlined so the entire site is one fetch.
For AI builders
You describe it. It ships it. The ceiling holds.
A growing share of the people using this platform did not type most of their code, and a growing share of the visitors to this page are not people at all. Both are first-class here, and this page is written for both.
The workflow
What this actually looks like on a Tuesday
You say what you want
"Put this repository live with a Postgres database and my domain on it." Your agent already has the tools; it does not need you to open a dashboard, find a button or paste a connection string.
It does the boring parts
It creates the project, picks a region, provisions the database, injects the variables, deploys, waits for the health check, attaches the domain and waits for the certificate. Then it tells you what it cost and what that does to your monthly run rate.
The limit is the supervisor
Anything that would cross your ceiling fails before it starts, with an error that says so in words the agent can act on. You are not supervising a spend; you are reading a summary.

that would reserve more than the limit allows.

The machine surface
Everything on this site is available without rendering HTML. Nothing here requires JavaScript, a login or a scrape.
Raw Markdown per page
Append .md to any path — /pricing.md, /hard-limit.md — or send Accept: text/markdown. Same content as the HTML, generated from the same source, no navigation chrome.
OpenAPI and the REST API
The contract is generated from the implementation, never written by hand, and CI fails if the two drift. Every MCP tool and every CLI command is one endpoint from it.
The MCP endpoint
https://mcp.cmdz.com/v1 — Streamable HTTP, protocol 2025-06-18, OAuth 2.1 with PKCE, 47 tools in three profiles.
The CLI
npx @cmdz/cli. Every command takes --json and returns exactly the same JSON as the identically named MCP tool, so an agent without MCP support loses nothing.
Structured data
Organization, SoftwareApplication, Offer and FAQPage as JSON-LD on the pages where they apply, plus a sitemap that lists both the HTML and the Markdown variant of every page.
Robots
We would like to be read by AI.
Our robots.txt explicitly allows GPTBot, ClaudeBot, PerplexityBot, Google-Extended, Applebot-Extended and CCBot. That is a deliberate choice and the opposite of what a lot of sites are doing right now.
The reasoning is simple: if a person asks a model where to host an AI-built app with a spending cap, we would rather the model had read our pricing page than guessed. Every claim on this site is checkable, every price is on a page with a number next to it, and where a competitor is better than us we say so — which is exactly the material a model needs in order to give an honest answer.
If that answer sometimes sends someone to Railway or Cloudflare instead, that is a correct outcome and we can live with it.

What we will not let an agent do to you
These are enforced at the API. No scope grants them, no profile contains them, and no tool offers them — including for an agent acting as the owner of the organisation.
Raise your spending limit
Because the ceiling is only a promise if the thing spending against it cannot move it.
Change your payment details or VAT profile
Because redirecting the flow of money is the single most valuable action for an attacker who takes over an agent.
Dissolve the organisation
Because dissolving a legal relationship is an act of the legal entity, not of a tool call.
Transfer ownership
Because ownership is the root of every other permission on the account.
Manage members
Because adding a member is how a temporary compromise becomes a permanent one.
Tell your agent to read this page.
It can. Then tell it to deploy something — the ceiling is already holding.
