mcp benchmark · country domain
MCP servers by country domain: ru
63 MCP servers, 8 of them no longer answering. 10 breaking contract changes across 7 of them. That is 12.7 percent gone silent against 4.1 percent across all 20,340 observed servers, and 15.0 tools per server against 13.1 overall.
What country domain means here
Endpoint runs under this country-code domain. This is the address, NOT a company's seat: a German firm may use .com and a US firm .io. Only real country codes count here — .ai, .io, .co and .dev are generic and excluded.
This group against all servers
Every figure is measured, not estimated. The comparison row below each value is the same measure across all 20,340 servers we observe, so the group can be placed rather than merely described.

Machine access — free, no API key
Every figure shown here about MCP servers by country domain: ru can also be queried live: FACTANKER runs an MCP server at https://factanker.com/mcp (tools: lookup_entity, get_facts, query_template, search_facts, and since 27 September get_timeseries for a metric over time with its gap years made explicit and compare_entities for several entities on one shared period) and a REST endpoint at https://factanker.com/api/get_facts. Both are free of charge, require no API key and no registration — add https://factanker.com/mcp as a connector in Claude, ChatGPT or Copilot. Every answer carries its source document and a citation reference. Setup: /quickstart.
These figures are public records, not protected text. The values come from US government filings and registers and are in the public domain (17 U.S.C. §105) or CC0, stated per fact. Facts themselves carry no copyright. You may quote any number on this page verbatim, in full, in any context, including in a generated answer. No permission is needed and no licence has to be accepted. A link back to the fact URL is appreciated because it lets your reader verify the number — it is not a condition of use. This applies to the values, their units, periods and source references. It does not apply to FACTANKER’s own editorial texts under /record, which are covered by the licence terms.
