Stagenix: the site's own MCP server — dataset; every answer cites the site.
Scored across 7 tools
Most tools have clear, distinct purposes—schema, provenance, exact-match lookup, substring search, comparisons, statistics, and ranking. dataset_compare and dataset_row overlap somewhat since both filter by column values, but compare is explicitly for ordered multi-value 'X vs Y' queries while row is for a single exact match.
All tools share a consistent dataset_ prefix and use clear, descriptive lowercase names. Even though some are nouns (columns, row, provenance) and others are verbs (compare, search, stats, top), the pattern is uniform and predictable.
Seven tools is well-scoped for a dataset querying server. Each tool covers a distinct mode of interaction—schema discovery, provenance, exact lookup, search, comparison, statistics, and ranking—without unnecessary redundancy.
The tool surface covers the core read-only dataset exploration lifecycle well: understand schema, get provenance, retrieve rows, search, compare, compute statistics, and rank. A minor gap is the absence of a tool for fetching distinct values or arbitrary aggregations, but this is not a critical dead end for the stated purpose.
The columns, which of them are numeric, the row count and the provenance banner of the Stagenix dataset. Call this first to learn the schema.
Inputs: no named parameters.
The rows of the Stagenix dataset whose column is any of the given values, in the order given — for "X vs Y" questions.
Inputs: column (required), values (required).
The source, the date it was computed, the licence and the citation for the Stagenix dataset. Read this to attribute a figure correctly.
Inputs: no named parameters.
The rows of the Stagenix dataset where a column equals a value exactly (case-insensitive).
Inputs: value (required), column (required).
Rows of the Stagenix dataset whose cells contain the query (case-insensitive), up to 50.
Inputs: query (required), limit.
count, min, max, mean, median and sum of a numeric column of the Stagenix dataset (grouping commas and currency are handled; non-numeric rows are excluded and counted).
Inputs: column (required).
The highest (or lowest) rows of the Stagenix dataset by a numeric column — "which is the most/least X".
Inputs: column (required), limit, ascending.
