THE RECORD

Coverage and gaps

RNWY keeps a dated daily record of whether listed MCP servers answered. A record is only as useful as it is honest about itself, so this page lists what it covers, when that changed, and every day it is missing. It is built from the data and updates on its own.

Record began Apr 12, 2026. Days with data: 153 of 213. Gaps: 5.

Coverage changes

  • Apr 12, 2026 · Daily uptime record begins: remote MCP servers listed through Smithery. Any reply within 6 seconds counts as answered.
  • May 28, 2026 · The ERC-8004 agent index runs for the last time before being paused. Agents registered after this date are not yet indexed.
  • Nov 10, 2026 · Public write access closed. Until this date several RNWY database tables, including agent scores, accepted writes from anyone holding the site's public key. The daily uptime table was not among them.
  • Nov 11, 2026 · Coverage widened to every Smithery and Official MCP Registry server with a public address, checked every day in a fixed order, with reply codes stored. Until then about 1,000 servers were checked a day, a different selection each day, because of a database row limit.
  • Nov 11, 2026 · An alarm now emails RNWY if a day of the record is missing or short. It runs outside the system that runs the checks.
  • Nov 11, 2026 · MCP scoring method mcp-1.1: a server RNWY has never checked is no longer scored as if it were down. Its reliability is shown as unknown, its quality is scored on the other measured dimensions, and it is capped at 60.
  • Nov 11, 2026 · RNWY stopped deleting its dated trust-score snapshots. Until this date, snapshots older than 10 weeks were deleted every night, so dated scores before early September 2026 are not kept.
  • Nov 11, 2026 · Delistings from the Official MCP Registry are now recorded with a date (deprecated or deleted). Removals from Smithery and Glama cannot be detected yet.
  • Nov 11, 2026 · A daily usage summary with no personal data is now kept permanently. Raw usage logs, which contain IP addresses, are still deleted after 90 days.

Gaps

  • Jul 13, 2026 to Jul 31, 2026 · 19 days with no uptime data
  • Aug 18, 2026 to Aug 31, 2026 · 14 days with no uptime data
  • Sep 18, 2026 to Sep 30, 2026 · 13 days with no uptime data
  • Oct 16, 2026 to Oct 26, 2026 · 11 days with no uptime data
  • Oct 29, 2026 to Oct 31, 2026 · 3 days with no uptime data

A gap means no check ran that day. It does not mean the servers were down. RNWY never fills a gap after the fact.

"Answered" means the address sent any reply within 6 seconds. From November 11, 2026 the reply code is stored too, so a gateway answering with an error can be told apart from a working server.
