A side-by-side look at the Power Bi MCP and Semiotic MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Power Bi MCP for data visualization work; choose Semiotic for data visualization as a local process. You can also run both side by side in one mcpServers block.
renderChart, renderInteractiveChart, getSchema.Rows where the two servers differ are marked.

renderChartRender a Semiotic chart to static SVG. Supports the components returned by `getSchema` that are marked `[renderable]`. Pass `{ component: "LineChart", props: { data: [...], xAccessor: "x", yAccessor: "y" } }`. Returns SVG string plus a "Render evidence" JSON block (mark counts by scene type, resolv…renderInteractiveChartRender a static-data chart as a ChatGPT Apps widget. Uses the same Semiotic server render path as `renderChart`, then hydrates an iframe UI with fit, zoom, data, hover, and render-evidence controls.getSchemaReturn the prop schema for a specific component. Pass `{ component: "LineChart" }` to get its props, or omit `component` to list the complete schema-backed catalog. Components marked `[renderable]` are available through `renderChart`; realtime charts require a browser/live environment.suggestChartSample-row recommender. Pass `{ data: [{...}, ...] }` with 1–5 sample objects plus optional broad intent/capability filters.suggestChartsCapability-based recommender for bounded row data. Returns ranked chart suggestions with scores, reasons, caveats, import paths, and ready-to-use props.suggestStreamChartsRecommend streaming charts from a schema (shape, key, throughput). Returns `{ suggestions, excluded, stretchSuggestions }`.suggestStreamDashboardCompose a multi-panel dashboard from stream schemas and an audience layout policy.suggestDashboardBuild a multi-panel dashboard suggestion that covers distinct analytical intents.suggestStretchChartsRecommend audience-literacy stretch picks from an `AudienceProfile`.repairChartConfigCheck whether a requested chart fits a dataset and return ranked alternatives when it does not.interrogateChartReturn a statistical summary and chart-aware context for answering natural-language questions with optional annotations.diagnoseConfigCheck a chart configuration for common problems — empty data, bad dimensions, missing accessors, wrong data shape, and more. Returns a human-readable diagnostic report with actionable fixes.Paste either block (or both) into your client config, e.g. claude_desktop_config.json or ~/.cursor/mcp.json. We only show a config when the install command is confirmed.
