MCP readiness
B · 84/100
Readiness is how fully this listing follows its protocol and how it behaved in our probes over 30 days. It is shown for reference and does not move it in search. Search order and leaderboards use the separate quality grade (here C+, 66.0/100), which weighs availability, conformance, p95 speed and descriptor. How the two differ
| Valid MCP handshake | 10/10 | initialize and tools/list both answered. |
| Live MCP endpoint | 24/25 | Endpoint answers the MCP initialize handshake (3551 ms); slow response -1. |
| Protocol revision | 6/10 | Speaks MCP 2025-06-18, 2 revision(s) behind 2026-07-28. |
| Signed descriptor | n/a | No MCP standard defines a signed server descriptor. |
| Uptime (30 days) | 15/15 | 23/23 probes succeeded over 30 days (100%). |
| Tool declaration | 10/10 | Lists 5 tool(s) with descriptions. |
| Verified identity | 7/10 | Namespace verified by the official MCP Registry (GitHub or DNS proof at publish time). |
| Freshness + modern flags | 2/5 | seen within 30 days. |
| Auth declaration | 2/5 | Declares credential scheme: bearer_api_key. |
Applicable criteria total 90 points, scaled to 100.
Responsiveness: Slow
(3551 ms; bands ≤2.5 s, ≤5 s, ≤8 s, slower; penalty only).
Measured 2026-11-11.
Nine criteria, the same as the A2A readiness score, read from our daily MCP probe (initialize + tools/list) and 30-day probe history. No MCP standard defines a signed server descriptor, so that criterion is n/a and the other 90 points are scaled to 100. Grades: A>=90, B>=75, C>=60, D>=40, F<40. Display only: search order uses the quality grade.
