## Trust

- hygiene: 80
- liveness: 100
- freshness: 85
- provenance: 90
- drivers: +repository +namespace-matches-repo +website +reachable +uptime-100% ~updated-50d-ago -duplicate-repo(16 names)
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 91/100 (strong)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-11-25; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### 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: 100 (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
- pass `tools.annotations`: 2 of 2 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 316 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`: 2 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: 2, about 316 tokens to load them all
- tool set hash: bb8cd1125090e19ee061f46cfd829250
- tools last changed: 2026-10-03T10:44:14.570Z
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.physics-star-cat/databutler-provenance.svg)](https://protogrid.dev/servers/io.github.physics-star-cat/databutler-provenance)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Packages

_none_

## Tools (2)

- `domain_provenance`: Who runs this domain? Live RDAP lookup: registration date and age, registrar, nameservers, status, whether the registrant is redacted, plus a typosquat check (edit-distance / brand-substring) against high-value brands. A very recently registered domain resembling a bank or big brand is a classic phishing signal — but report it as a signal, not a conclusion.
- `package_provenance`: Who publishes this package, and is it a typosquat? Live npm or PyPI lookup: first-publish date and age, release count, latest version, maintainers/author, linked repo, plus a typosquat check against popular package names. Use when an agent is about to install or recommend an unfamiliar dependency.
