> Counterparty due-diligence infrastructure: OFAC screening, on-chain risk, signed verdicts.

- name: io.github.stillmarcus24/stillos-kya
- version: 0.4.3
- connection class: R0 (autonomous)
- trust: 94/100
- quality: 77/100 (good)
- owner: not claimed
- descriptor: https://api.protogrid.dev/v1/servers/io.github.stillmarcus24%2Fstillos-kya

**An agent can connect right now, no human step.** Remote endpoint, no authentication, reachable on the last probe.

## Connection (mcpServers)

```json
{
  "mcpServers": {
    "stillos-kya": {
      "type": "http",
      "url": "https://stillos-kya-edge.stillos.workers.dev/mcp"
    }
  }
}
```


## Trust

- hygiene: 100
- liveness: 99
- freshness: 100
- provenance: 80
- drivers: +repository +namespace-matches-repo +reachable +uptime-97% +updated-27d-ago
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 77/100 (good)

### protocol: 88 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session
- pass `protocol.transport`: streamable HTTP
- warn `protocol.list_ttl`: tools/list declares ttlMs 0, so clients re-fetch it on every use

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 71 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- fail `tools.annotations`: no tool declares readOnlyHint or destructiveHint, so clients cannot tell safe calls from risky ones
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: kya_check (readOnlyHint, destructiveHint, idempotentHint, openWorldHint)
- pass `tools.token_cost`: about 157 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: no tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: 50 (weight 15)

- fail `deps.known_vulns`: 1 advisory to act on (malicious, or rated high or critical with a fix available): GHSA-96hv-2xvq-fx4p in ws@8.18.0 (indirect, fixed in 8.21.0); 4 more of lower severity or without a fix
- n/a `deps.mcp_sdk_version`: the official MCP SDK is not in the dependency graph
- pass `deps.resolvable`: stillos-kya@0.4.3 resolved: 469 packages

- tools: 1, about 157 tokens to load them all
- tool set hash: c531a136cbad72ea2142add8546b905f
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.stillmarcus24/stillos-kya.svg)](https://protogrid.dev/servers/io.github.stillmarcus24/stillos-kya)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

- `kya_check`: Know Your Agent (KYA): screen a counterparty agent BEFORE paying it. Returns a fail-closed verdict -- CLEAR, REVIEW, or BLOCK -- from an OFAC SDN sanctions screen plus live on-chain wallet signals, with an Ed25519-signed proof-of-diligence receipt on the paid tier. Call this before any agent-to-agent payment.
