BreakerDesk: the site's own MCP server — dataset; every answer cites the site.
com.breakerdesk/site is a remote MCP server published at breakerdesk.com. It has been probed 8 times since 9/12/2026. It answered in 8 of them (100.0%), a near-uninterrupted record. Median response time is 621 ms, a delay an agent will notice. It offers a narrow, focused set of 7 tools. On the protocol side it still runs 2025-11-25 and has not moved to the newer spec.
Can an LLM agent pick the right tool here — names, descriptions and parameter clarity are assessed.
dataset_compare — Description could clarify 'values' array usage context.dataset_search — No mention of query length limits or empty query handling.dataset_stats — No explicit handling of non-numeric column errors.Risk: low
tools/list structure, inputSchema validity, and a functional smoke test — the components of the 0-100 score.
Tools the server advertised in the latest measurement — measured, not catalog-claimed.
dataset_columnsThe columns, which of them are numeric, the row count and the provenance banner of the BreakerDesk dataset. Call this first to learn the schema.
dataset_searchRows of the BreakerDesk dataset whose cells contain the query (case-insensitive), up to 50.
querystringrequiredlimitintegerdataset_rowThe rows of the BreakerDesk dataset where a column equals a value exactly (case-insensitive).
columnstringrequiredvaluestringrequireddataset_compareThe rows of the BreakerDesk dataset whose column is any of the given values, in the order given — for "X vs Y" questions.
columnstringrequiredvaluesarrayrequireddataset_statscount, min, max, mean, median and sum of a numeric column of the BreakerDesk dataset (grouping commas and currency are handled; non-numeric rows are excluded and counted).
columnstringrequireddataset_topThe highest (or lowest) rows of the BreakerDesk dataset by a numeric column — "which is the most/least X".
columnstringrequiredlimitintegerascendingbooleandataset_provenanceThe source, the date it was computed, the licence and the citation for the BreakerDesk dataset. Read this to attribute a figure correctly.
Derived by comparing consecutive probes — changes in era, protocol version, build and reachability.

Each block is one measurement round. Green: working response. Amber: responded but the server was returning errors (5xx). Red: no response at all.
Each cell is one probe run. Faded cells are incomplete probes — one leg did not answer, so the era is inconclusive.
The two probe legs separately: modern server/discover and legacy initialize.
