Votre carte d'agent est-elle lisible par les autres agents ?
Un agent se présente par une carte publiée sur /.well-known/agent-card.json. C'est le seul document qu'un autre agent lit avant de décider de vous appeler. Cet outil va la chercher, la confronte à la spécification, et vous rend le détail.

Compétences déclarées
- A2A ecosystem, measuredHow many projects use the A2A (Agent2Agent) protocol, counted daily from declared repository topics: total, created in the last year, active, dormant, abandoned, and by language. Every figure carries the date it was measured.
- MCP ecosystem, measuredHow many servers are published for the Model Context Protocol, counted daily from the official registry, with the same breakdown and the date of the reading.
- Search the measured catalogueSearch the KoPass catalogue of developer tools, libraries, CLIs, MCP servers and agent skills. Results come from daily readings, never from an editorial list.
- Find an A2A agent by capabilityFind deployed A2A agents by the skills they declare, among those whose card KoPass read at their own well-known location and that still answered on the latest reading. Each result carries the date it last answered.
- Everything known about one agentReturn the full record KoPass holds for one A2A agent, by its host name: declared skills, conformance verdict, protocol version, since when it has been followed, and the date it last answered.
- A2A card conformance, measuredReturn the dated conformance figures across every agent card KoPass reads daily: how many are conformant, how many still use the shape from before v1.0, how many are signed, and the most frequent faults.
- Validate an A2A agent cardRead the agent card published at an address and report what the A2A specification says about it, field by field, including whether it uses the shape from before v1.0.
