Unmeasured means there is not enough evidence to decide. How these checks work
Start using Polyxd
Choose your client, copy the configuration, then enable the server in your client’s MCP settings.
Run this command in your terminal, then restart Claude Code.

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.
DiscoveredSearches the polyxd.com docs, as of this server's version: installing and using the React and Web Components renderers, the spec, the verifier and its CLI, the runtime, the generation server, design systems and packs, Design Directions, analytics events, Studio, the MCP server and the roadmap. Pass "query" for the sections that best match, "page" for one whole page, or nothing for the list of pages. Cite the URLs it returns. For writing a document, use polyxd_guide.
DiscoveredReturns 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.
DiscoveredLists 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.
DiscoveredValidates 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.
DiscoveredChecks 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.
DiscoveredRuns 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.
