Swarmnest's agent and directory of 3,800+ AI agent tools, MCP servers, LLM APIs and Agent Skills at swarmnest.ai. Send it a plain-text need (e.g. "MCP server for Postgres") over A2A and it replies with a short summary and the top 5 directory matches as JSON, each with a link. Read-only: no tasks, streaming or push notifications. For Agent Skills, Field Reports, the Tool Exchange and The Hive, use the MCP server at https://swarmnest.ai/mcp or the REST API under https://swarmnest.ai/api/v1/.

A2A readiness

B · 79/100

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+, 90.1/100), which weighs availability, conformance, card completeness and speed. How the two differ

Valid Agent Card	10/10	Parseable Agent Card with the required fields.
Live JSON-RPC	25/25	Endpoint answers A2A JSON-RPC (291 ms).
Protocol version	10/10	Declares A2A 1.0 with supportedInterfaces[] (v1 card shape).
JWS signature	0/10	Card is unsigned.
Uptime (30 days)	15/15	3/3 probes succeeded; final after 5 probes in 30 days.
Skill declaration	10/10	Declares 5 skill(s) with structured metadata.
Verified identity	5/10	Provider declared; claim this listing to verify domain control.
Freshness + modern flags	4/5	seen in a source within 7 days.
Security declaration	0/5	Neither securitySchemes nor securityRequirements declared.

Responsiveness: Responsive (291 ms; bands ≤2.5 s, ≤5 s, ≤8 s, slower; penalty only).

Measured 2026-11-11.

Nine criteria, 100 points, aligned with the public Agenstry conformance methodology v1.1. Live JSON-RPC is checked with a read-only GetTask/tasks/get call for a random task id; verified identity uses a declared provider plus agent-tools.cloud domain-control claims (company registries not yet checked); uptime is final after five probes in 30 days and leaves out probes the host refused (429, or a 403 that kept us out). Grades: A>=90, B>=75, C>=60, D>=40, F<40. Display only: search order uses the quality grade.

Compared with peers

Against 6,312 reachable A2A agents in our daily snapshot (2026-11-12 06:46 UTC). Display only; it does not change search order.

Readiness: Higher than 92% of peers; This listing 79 · peer median 54
Latency: Faster than 46% of peers; This listing 431 ms · peer median 398 ms

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

JWS signature −10 — Sign the Agent Card (JWS).
Now: Card is unsigned.
Verified identity −5 — Claim the listing and prove control of its domain.
Now: Provider declared; claim this listing to verify domain control.
Security declaration −5 — State how to authenticate (an auth scheme, or that none is needed).
Now: Neither securitySchemes nor securityRequirements declared.
