Is the VizForge MCP server free?

Yes. Every tool is free and needs no account, API key or credits. The tools run the same deterministic code as the free tools on vizforge.ai; none of them calls an AI model. The paid AI custom-visual generator is not exposed through MCP.

What is sent to VizForge, and is anything stored?

Only the tool arguments your assistant sends: template or theme slugs, colours, layout choices, search words, a design link or design JSON. The server answers from them and keeps nothing: there is no database write, no session and no cookie, and request bodies are not logged. The hosting platform keeps standard request logs (time, IP address, status) as it does for every page.

60 requests a minute per IP address and a 256 KB request body. Large results are returned as vizforge.ai links (for example a design link) rather than inlined, and results are capped at about 200 KB.

Can the tools change anything in my Power BI reports?

No. All tools are read-only: they return JSON, SVG, DAX and links. Nothing touches your Power BI tenant or files. You import the theme JSON or paste the DAX yourself.

Which MCP versions and transports does it support?

Streamable HTTP at one endpoint, stateless, one JSON response per POST. Protocol versions 2026-07-28, 2025-11-25, 2025-06-18, 2025-03-26: the current revision's per-request metadata and server/discover, and the earlier initialize handshake. There is no SSE stream (GET returns 405) and no session id.

The VizForge MCP server for Power BI design

Give your AI assistant VizForge's free Power BI design tools. Once it is connected, Claude, Cursor, VS Code or ChatGPT can search the templates and themes, turn brand colours into a theme JSON, lay out a page and hand you a link that opens it in the Design Studio, score a design with Design Check, and write DAX SVG measures. Every tool is deterministic: no AI model runs on our side and no credits are used.

Server URL

https://vizforge.ai/api/mcp

Streamable HTTP, no authentication. Paste it into any MCP client that supports remote (HTTP) servers.

Install it in your client

Claude (claude.ai and Claude Desktop)

Open Customize → Connectors, select + Add, then Add custom connector (Team and Enterprise plans: an Owner adds it under Organization settings → Connectors first).
Name it VizForge and paste the server URL.
Under Authentication choose No sign in, then Add.
In a chat, enable VizForge from the + button → Connectors.

Server URL

https://vizforge.ai/api/mcp

Claude connects to remote connectors from Anthropic's cloud, so the same connector works in claude.ai, Claude Desktop and the mobile apps. Free plans are limited to one custom connector.

Tool reference

Generated from the same definitions the server returns from tools/list. Every tool returns a short text summary and structured JSON; large artifacts come back as vizforge.ai links.

list_templates

List Power BI dashboard templates

Search VizForge's free Power BI report templates (61 designed pages). Use this when someone wants a starting layout for a Power BI report or dashboard, e.g. "a dark finance dashboard with 4 KPIs". Filter by category, industry words, light/dark mode, accent colour, KPI-card count and whether a PBIP with sample data ships. Returns slugs plus page, preview-image and open-in-studio URLs; call get_template for one template's details.

category	one of 22 values	Template category (department or industry).
industry	string	Industry or department words, e.g. "healthcare", "retail", "hr". Matched against category labels and tags.
mode	light \| dark	Light or dark page.
colour	one of 9 values	Dominant accent colour family.
kpiCount	integer 0–12	Exact number of KPI cards on the page.
minKpis	integer 0–12	At least this many KPI cards.
maxKpis	integer 0–12	At most this many KPI cards.
hasSampleData	boolean	Only templates that download as a PBIP with a bound sample semantic model.

Try: “Find me a dark Power BI template for a hospital with at least 4 KPI cards.”

get_template

Get one template

Details of one VizForge Power BI template by slug (from list_templates): what the page is for, its layout, suggested DAX measures, the sample semantic model (tables, measures, relationships) when one ships, and URLs for the template page (free downloads: PBIP with sample data, empty PBIP, PNG/SVG background, theme JSON), the preview image, and the Design Studio (light and dark versions). Use it before recommending or explaining a specific template.

Parameter	Type	What it does
slugrequired	string	Template slug, e.g. from list_templates.

Try: “What's in the VizForge CFO overview template and which measures does it use?”

list_themes

List Power BI themes

Search VizForge's 80 free Power BI report themes (contrast-checked theme JSON). Use this when someone wants a ready-made Power BI theme by mode (light/dark), accent colour or colour-blind safety. Returns slugs, colours and fonts; call get_theme_json for the importable JSON.

Parameter	Type	What it does
query	string	Words matched against title, summary and tags.
mode	light \| dark
colour	one of 9 values	Accent colour family.
colorBlindSafe	boolean	Only palettes built on a published colour-blind-safe scheme.

generate_theme_from_colors

Power BI theme from brand colours

Turn brand colours (a hex list, a coolors.co link or any text containing hex codes) into a Power BI theme JSON: the colours become dataColors, an accent is picked, and every text and data colour that misses WCAG AA contrast is darkened or lightened without changing its hue; the page background may be tinted and the good/neutral/bad status colours adjusted too (every change is listed). Use it when someone gives you their brand palette and wants a Power BI theme. Same code as the Design Studio's brand import and “Upgrade theme”.

Parameter	Type	What it does
colors	list of string	Hex colours, e.g. ["#0B5394", "#F1C232"]. The first 12 become data colours.

dax_svg_measure

DAX SVG measure

Write a DAX measure that draws a small SVG chart inside a Power BI table, matrix or card (set the measure's Data category to Image URL). 17 patterns: sparkline (Sparkline (line)), sparkline-area (Sparkline (area)), column-sparkline (Column sparkline (small multiple bars)), win-loss (Win/loss bars), bullet-chart (Bullet chart), progress-bar (Progress bar), progress-ring (Progress ring), data-bar-target (Data bar with target), kpi-delta-badge (KPI arrow / delta badge), traffic-light (Traffic light / RAG dot), status-pill (Status pill), rating-stars (Rating stars), icon-value (Icon + value), variance-bar (Variance bar (IBCS style)), dumbbell (Dumbbell (before / after)), mini-donut (Mini donut), kpi-card (KPI card (value, delta, sparkline)). Returns the measure, a DAX user-defined function (UDF) version, the SVG it renders for sample data and a link to the visual builder. Use it when someone wants sparklines, bullet charts, progress bars, status pills or KPI cards in a Power BI table without a custom visual. Pass options to set the measure/column references (e.g. {"value": "[Sales]", "axis": "'Date'[Month]"}); unknown option keys are listed in the result.

Parameter	Type	What it does
patternrequired	one of 17 values	Pattern slug.
