## Trust

- hygiene: 100
- liveness: 97
- freshness: 100
- provenance: 80
- drivers: +repository +namespace-matches-repo +reachable +uptime-92% +updated-22d-ago
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 83/100 (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: payment_preflight (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); vendor_preflight (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); resolve_company (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 858 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`: 1 tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

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

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 5, about 858 tokens to load them all
- tool set hash: 00428849a9653d96f9b32c65f17d2a43
- tools last changed: 2026-10-14T14:49:15.364Z
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.Andy229651/agentkyb.svg)](https://protogrid.dev/servers/io.github.Andy229651/agentkyb)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Packages

_none_

## Tools (5)

- `check_domain`: Check public RDAP registration evidence for a domain, including registration status, registrar, dates and registry information.
- `payment_preflight`: Fast pre-payment consistency guard for AI agents. Checks HTTPS destination, EVM payTo format, Base network, amount validity, and detects recipient/network/price changes against caller expectations. Returns allow/review/block. Use vendor_preflight for deep KYB.
- `resolve_company`: Resolve a business or vendor name to an official legal entity using AgentKYB's global and national business-registry sources. Returns legal name, registration number, jurisdiction, status, LEI when available, confidence, and source corroboration.
- `screen_sanctions`: Screen a company, vendor, or counterparty name against AgentKYB's indexed official sanctions sources including OFAC SDN, OFAC non-SDN, UK Sanctions and UN sanctions. Potential matches require human/compliance review.
- `vendor_preflight`: Verify vendor identity before paying: KYB, supplier risk and counterparty checks for AI agents. Returns allow/review/block with legal-entity evidence, potential sanctions signals, RDAP domain evidence and company-domain consistency. Payment safety decision support via x402; not legal or transaction approval.
