u-Slicer MCP¶
What MCP is¶
MCP (Model Context Protocol) is an open protocol that standardizes how AI assistants connect to external data sources and tools. A service exposes a set of tools (functions the assistant may call), and the assistant decides when to call them, with which arguments, and how to present the result.
The u-Slicer MCP server exposes u-Slicer as such a set of tools. Once your AI assistant is connected to it, you can ask questions about your data in plain language, and the assistant queries u-Slicer for you instead of you building the report by hand.
What it is for¶
Typical uses:
- Ad-hoc questions: "Using u-Slicer, show me the top 10 publishers by revenue last week" — the assistant picks the slicer, the dimensions and the measures, runs the query and returns the table.
- Following a trend: "How did impressions evolve day by day in July, split by country?"
- Explaining a report: paste a u-Slicer link into the chat and ask what it shows, or ask for the same data with one more breakdown.
- Analysis on top of the numbers: the assistant can compare periods, compute ratios, spot outliers and summarize findings, because it receives the data rows, not a picture.
- Discovering a slicer: "Which measures does this slicer have, and what does
<column>mean?" — the schema includes the notes written by the slicer maintainers.
Every answer from the query, time_series and query_url tools comes with a
proof link — a URL that opens the same data in the u-Slicer UI, so you can
verify what the assistant told you.
What it is not¶
- It is not a replacement for the UI. The MCP server has no dashboards, no bookmarks, no export scheduler. It answers questions.
- It is not a separate data source. The server is a thin wrapper over the APIv2: same data, same aggregation, same permissions.
- It does not raise your access level. You see exactly the projects, slicers and columns your u-Slicer account is allowed to see. If you cannot open it in the UI, the assistant cannot read it either.
- The assistant is an LLM and can be wrong — it may pick a column you did not mean, or a period slightly off. Check the proof link when the number matters.
