Phast app

Canonical source of truth for Phast app.

Connect your tools once. Bring your tool belt anywhere.

Phast app gives a person one portable MCP plus a programmable Prefab home. Connect my.phast.app/mcp to an agent to create and manage Phast apps. A created Phast app has two matching surfaces:

user.phast.app — human / Prefab home
user.phast.app/mcp — the user's portable MCP tool belt

V0 contract

phast.json is deliberately boring. It is mostly:

the MCP tool list and provider connections;
references to delegated credential authority (Persimmons, never raw secrets);
Prefab home/widget settings.

The browser and chat are two editors for the same declaration.

Browser flow

Home → Edit Home → Add Widget → provider search → connect if necessary → place/configure widget.

Agent flow

Connect once to my.phast.app/mcp → create/manage user.phast.app → search providers → add tools/widgets → stream/taste-test Prefab in chat → persist accepted UI to the same phast.json.

Boundaries

Phast app composes. It owns the portable MCP/tool belt and Prefab composition.
Oracle discovers. Provider/MCP/OAuth discovery comes from the capability graph, not a hard-coded Phast app directory.
Persimmons holds secrets. Phast app stores connection/authority references, not secret values.
Factory builds/operates. Provisioning uses bounded deterministic infrastructure routes.
Clients are replaceable. ChatGPT, Claude, Codex, or another MCP client should be able to use the same Phast app without recollecting the user's tools.

V0 is intentionally not arbitrary app generation. Prove the portable-tool-belt + editable-home loop first.

Naming and copy

Use Phast app when naming the product or one of its instances; use Phast apps for the plural. Write “your Phast app,” “create a Phast app,” and “My Phast app” for the management connector. Existing all-caps display styles may use “PHAST APP.” Apply this to page titles, metadata, navigation, buttons, examples, generated homes, MCP display text, and documentation.

Keep deliberate substitutions for “fast”: “make something phast,” “built phast,” and “make MCP apps phast.” Do not rename literal domains, URLs, phast.json, environment variables, CSS classes, tool names, or schema keys/values as part of a copy edit. Preserve user-chosen app names.

The public copy lives in index.html (phast.app), my/index.html (my.phast.app), and server.py (generated personal homes and MCP display text). phast.json supplies the management display name. Review these surfaces together when changing product naming.

Chair review: the standalone “PHAST.” wordmark and the “My Phast” connector label could be separate brand treatments. This change proposes “PHAST APP.” and “My Phast app” consistently; the chair should confirm those treatments. The phrase “your Phast” names an app instance, so it becomes “your Phast app.”
