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 B+, 94.1/100), 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	25/25	Endpoint answers the MCP initialize handshake (367 ms).
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	9/9 probes succeeded over 30 days (100%).
Tool declaration	10/10	Lists 4 tool(s) with descriptions.
Verified identity	8/10	Publisher declared (repository, package or homepage) and domain control verified on agent-tools.cloud (company-registry check not available yet).
Freshness + modern flags	2/5	seen within 30 days.
Auth declaration	0/5	How to authenticate is not stated.

Applicable criteria total 90 points, scaled to 100.

Responsiveness: Responsive (367 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.

Compared with peers

Against 53,039 reachable MCP servers in our daily snapshot (2026-11-12 06:46 UTC). Display only; it does not change search order.

Readiness: Higher than 75% of peers; This listing 84 · peer median 81
Latency: Faster than 74% of peers; This listing 181 ms · peer median 326 ms

Where it loses the most points, and how to win them back

Auth declaration −5 — State how to authenticate (an auth scheme, or that none is needed).
Now: How to authenticate is not stated.
Protocol revision −4 — Support the current protocol revision.
Now: Speaks MCP 2025-06-18, 2 revision(s) behind 2026-07-28.
Freshness + modern flags −3 — Keep the listing current in the registry or source it comes from.
Now: seen within 30 days.
