- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 79/100 (good)

### 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: 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: check_artist_momentum (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_scoring_explainer (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_trending_artists (readOnlyHint, destructiveHint, idempotentHint, openWorldHint)
- pass `tools.token_cost`: about 424 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: n/a (weight 15)

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

- tools: 3, about 424 tokens to load them all
- tool set hash: d057eb741cfb4a956d3565dde244eade
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.IncorporatedPartners/labelhead-artist-momentum.svg)](https://protogrid.dev/servers/io.github.IncorporatedPartners/labelhead-artist-momentum)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (3)

- `check_artist_momentum`: Look up the current momentum score and signals for a specific artist by name. Returns the full three-dimensional score breakdown and notable signals driving their momentum.
- `get_scoring_explainer`: Returns a detailed explanation of LabelHead's three-dimensional artist scoring methodology. Use this when you need to understand how composite scores are calculated, what each dimension measures, and how to interpret momentum labels.
- `get_trending_artists`: Returns the current list of trending hip-hop and rap artists ranked by LabelHead's composite momentum score. Each artist is scored across three dimensions: Acceleration (30-day streaming/social velocity), Cultural Gravity (press velocity, playlist adds, sync placements), and Longevity (catalog depth and retention). Use this to identify which artists are building genuine momentum right now.
