api record

Polyxd turns a small JSON document of meaning into a real screen in a design system. You write the document; this server checks it and shows it to the user. Call polyxd_guide once before writing your first document, polyxd_validate until it is valid, then polyxd_show. Actions the user takes in a shown screen come back to you as chat messages. A button press only tells you what the user chose: it submits, pays or saves nothing, so never say it did.

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • polyxd_components open 3h ago

    Lists the semantic components a Polyxd document can use, with a one-line summary each. Pass "name" for one component's full definition: every prop and its type, which are required, when to use it and when not to, and how it renders.

    mcp-tool

    {
  "type": "object",
  "properties": {
    "name": {
      "type": "string",
      "description": "A component name, e.g. \"Choice\", for its full definition."
    }
  }
}
    arguments 9 lines
  • polyxd_guide open 3h ago

    Returns the instructions for writing a Polyxd UI document: the document shape, the rules for generated screens, bindings, actions, every component with its props, and the patterns. Call this once before writing your first document.

    mcp-tool

    {
  "type": "object",
  "properties": {}
}
    arguments 4 lines
  • polyxd_packs open 3h ago

    Lists the design-system packs polyxd_show can draw a screen in: published design systems (Material 3, Carbon, GOV.UK and others) and original templates. The same document looks native in each.

    mcp-tool

    {
  "type": "object",
  "properties": {}
}
    arguments 4 lines
  • polyxd_validate unknown never probed

    Checks a Polyxd UI document against the spec: the schema, ids and references, bindings against the data, actions, and the rules for generated screens. Returns every issue with its JSON Pointer, the component it is in, and a hint saying what to change. Call it after writing or changing a document, and fix every error before showing it.

    mcp-tool

    {
  "type": "object",
  "required": [
    "document"
  ],
  "properties": {
    "data": {
      "type": "object",
      "description": "The values the screen shows, bound by {\"path\": \"/pointer\"}. Replaces the document's own \"data\" when given.",
      "additionalProperties": true
    },
    "document": {
      "type": "object",
      "description": "A Polyxd UI document: {specVersion, surface, root, components, data?}. polyxd_guide explains the format.",
      "additionalProperties": true
    }
  }
}
    arguments 18 lines
  • polyxd_verify unknown never probed

    Runs the Polyxd verifier's document checks: the spec validator, the pattern the surface declares, readable and distinct labels, one primary action per view, at most six inputs per view, entity-first flows, confirmations, and, when you pass one, a Design Direction's rules and voice. Returns a compact report. Example directions by name: calm-finance, playful-personal.

  • polyxd_show unknown never probed

    Validates a Polyxd UI document and shows it to the user as an interactive screen, drawn by the Polyxd renderer in the design-system pack you choose (default material3). Shows nothing if the document has errors; fix them first with polyxd_validate. When the user presses an action in the screen, you receive a chat message from the user naming the action and its context; that only tells you their choice, and nothing has been submitted or paid. Packs: material3, antd, bootstrap, carbon, chakra, fluent, govuk, mantine, polaris, primer, radix, shadcn, spectrum, brutalist, civic, editorial, finance, glass, health, mono, neon, pastel, sketch, terminal, wireframe.

Names like \"Carbon\" or \"shadcn/ui\" work too. Pass it whenever the user names a design system. Default material3."

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we know
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
