Prebuilt, interactive HTML widgets for MCP Apps in Go — data tables and forms, self-contained in a single binary, host-themed, spec-compliant.
Prebuilt, parameterized, interactive HTML widgets for MCP Apps — in Go, out of the box.
gadget lets an MCP server ship CRUD-style UI — data tables, card grids, forms — as fully self-contained HTML template resources: inline CSS, inline JavaScript, zero external files, everything embedded in your single Go binary. Widgets speak the official MCP Apps extension (io.modelcontextprotocol/ui, spec 2026-01-26) and render in any compliant host (Claude, ChatGPT, VS Code, Cursor, Goose, Postman, …).
Status: pre-release. APIs are not stable yet.
Table and Form widgets rendered by the examples/harness fake host — light and host dark themes.
CardList lays a collection out as a card grid (same filter/sort/pagination/selection as Table); Card renders a single record.
Ask a connected assistant to "list the users" and it renders an interactive, host-themed table — sortable, filterable, paginated — inside the chat.
- Table: typed columns (text/number/date/badge/link/actions), client-side sort/filter/pagination, row selection with bulk actions, per-row actions → MCP tool calls, inline destructive-action confirmation, empty/loading states. - Form: 10 field types, native + inline client validation, submit as a tool call, server-side field errors mapped inline, prefill for edit flows. - Host-aware theming: --gadget- design tokens defaulting to host-injected CSS variables (Claude/ChatGPT look automatic), Theme struct overrides, dark mode. - Locale-aware: numbers/dates formatted via Intl with the host's locale and time zone. - SDK-agnostic core + adapter for the official go-sdk; the core wor
