Your agent reasons; Capell builds
Build a Capell website with an AI agent.
The read side needs no credentials: an agent can list capabilities, fetch the interview script and the site-spec JSON schema, and validate a draft spec against the public endpoint. Preview, export, and build require an Agent Bridge token. Capell performs no AI inference itself — your agent does the reasoning and the writing.


Capell exposes its site-design capabilities over MCP. An AI agent can discover your themes, page and section types, and layouts, fetch the interview script and the site-spec JSON schema, and validate a draft — all without credentials. Preview, export, and build authenticate against an Agent Bridge token and stay audited. Capell runs no inference of its own: your agent does the reasoning and the writing, and Capell builds the validated spec deterministically.
How an agent builds a Capell site
Discover
List installed themes, page types, section types, and layouts the spec may use.
Interview
Fetch the deterministic interview script and ask the user in the agent's own words.
Assemble
Build a site spec — pages, sections, theme, copy — against the published JSON schema.
Validate
Run validate_spec until the draft is valid. No data is written.
Preview
Authenticate, then build a non-destructive preview before any deploy.
Build
Confirm the preview to publish, or export a portable spec and install command.
Two endpoints: public read, authenticated build
- Public read —
ai/capell/read: list capabilities, get the interview, get the site-spec schema, and validate a spec. No authentication. - Authenticated —
ai/capell: preview, export, build, and apply, behind an Agent Bridge token with per-token throttling. - The read endpoint runs a fixed allowlist of pure-read capabilities; the allowlist is the only trust boundary.
The agent proposes. Capell stays deterministic.
The agent assembles a spec; Capell validates and builds it the same way every time. Mutations are token-gated and audited, and a preview always precedes an irreversible build.

AI agent questions
Which agents can use this?
Do I need an API key for read access?
What can the public endpoint touch?
How does an agent build, then?
Next step
Give an AI agent a CMS it can actually build on.
Capell's structured Laravel model (pages, URLs, types, layouts) is what makes agent-built sites predictable.
