Horizun PBI MCP server

Horizun PBI MCP

Build and fix Power BI reports by describing what you want. Ask in plain language; the server runs the DAX, edits the model, writes the report pages — and checks its own work afterwards.

No licence, no API key, no paid plan

It runs as a local process on your own Windows machine, so the free apps are enough: install it in ChatGPT Desktop or Claude Desktop on their free tiers and start asking. No OpenAI or Anthropic API key, no subscription, no server of ours in the middle — and Power BI Desktop is free as well. One click installs it and it prepares its own runtime: no Python, no JSON to edit.

v2.1.1 · 139 tools · Windows · ChatGPT Desktop Free · Claude Desktop Free · Claude Code · Codex

New to the project? Start with what this Power BI MCP is, when to use it, and what it deliberately does not do.

Install

No repository clone, manual DLL download or .mcp.json editing is required. Pick the line that matches you.

ChatGPT Desktop Free

Run the verified one-paste installer from docs/INSTALL.md, restart ChatGPT Desktop, then open Plugins → Personal and install Horizun PBI MCP. No OpenAI API key is required.

Claude Desktop Free

Download the .mcpb from the latest release and double-click it. Claude Desktop supplies the bootstrap runtime; no Claude Code install or JSON editing is required. It will say the extension is not verified by Anthropic — what it says about anything installed outside its own directory — and let you continue.

Claude Code

claude plugin marketplace add HorizunGroup/horizun-pbi-mcp
claude plugin install horizun-pbi-mcp@horizun

Codex

codex plugin marketplace add HorizunGroup/horizun-pbi-mcp

Then open /plugins, pick the Horizun marketplace and install horizun-pbi-mcp.

Desktop or Code?

Same server, same 139 tools, same local runtime — install both and they share it. Pick by what you are doing: Claude Desktop to use Power BI, in chat, one click, free tier. Claude Code to build — it adds the terminal, git and your repo, and loads tool schemas on demand instead of all at once.

On a new PC, the verified one-paste installer prepares the prerequisites without administrator rights. First setup takes a few minutes: run pbiinstallstatus until ready, restart once, and confirm the 139 pbi_* tools appear.

Your first minute

1. Open Power BI Desktop with any report.
2. Ask: "List the Power BI models that are open and connect to the first one."
3. Ask: "Run a read-only DAX query that returns revenue by month for this year."

If step 2 answers, everything works.
