UI9000 workspace MCP. One tool, show_workspace, draws a chart from your table. Set TYPESAFE_API_KEY to let Jev choose the chart.

/**
 * Public data-link API: `signDataLink` / `readDataLink`.
 *
 * Assembled from mcp-ui `createDataLink` / `getDataLink`
 * (`src/utils/dataLinkHandlers.ts`) and the TTL resolution in
 * `chartDataLinkHelper.ts`. The signing and verification steps are unchanged —
 * see `signature.ts`.
 *
 * These two functions satisfy the `SignDataLink` / `ReadDataLink` contract in
 * `src/tool/data-channel.ts`: the payload never reaches the spec, only an
 * opaque `/v1/data-links/:id?sig=&exp=` handle does.
