MCP support
The DataArcus MCP provides the local report-writing and validation workflow. It checks reports on the user's machine before writing and includes a `check_report` operation.
Configuration
Local server config is the same for every client. Copy it into your client’s MCP config file.
We haven’t collected a package or remote endpoint for this server. Follow the instructions in the project README.
Tools
Local servers expose tools only once running on your machine, and the maintainer has not provided a tool list.

Power BI reports designed right, and checked in Power BI, not just generated. Arabic, right to left and the Gulf calendar, next to Microsoft's tools.

How we check our work
- Automated tests on every change: every website test suite (the list is
ALLinscripts/tests/run-all.mjs) and the MCP's tests run on each pull request and push to main. - Microsoft's own validator: our test runs check the reports the tools write, on our sample models, with
Microsoft's report validator. The website's tools don't run it on the reports you make in your browser; the
DataArcus MCP runs it on your machine on each report before it is written, and in
check_report. - Measured in Power BI Desktop: sizes, layouts and numbers are measured in Power BI Desktop, never estimated, and recorded with the version used.
- Sourced facts: prices, dates and Microsoft claims are linked to their source and re-checked. The Gulf calendar's
announced Ramadan and Eid dates for the UAE and Saudi Arabia, each with its source, are in
scripts/gulf-calendar/DATES-SOURCES.md.
Measurements
What was measured in Power BI Desktop, on which version, how, and the quirks found, is in
scripts/tests/DESKTOP-TESTS.md.
The AI report designer
An AI report designer for Power BI (it works with Claude on your own machine and writes new files only: the one file it ever replaces is its own answers file, after you approve) is in public beta: download 0.3.0 from the release page (check its SHA-256 there), install steps in mcp/README.md.

New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
