## Quality 81/100 (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: 86 (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`: 1 of 1 tools declare readOnlyHint or destructiveHint
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: check_npm_download_trust (idempotentHint)
- pass `tools.token_cost`: about 268 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

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

- n/a `stability.changes`, `stability.rug_pull`: tool history not recorded yet

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

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

- tools: 1, about 268 tokens to load them all
- badge: [![protogrid quality](https://protogrid.dev/badge/com.edgethirteen.www/pumpcheck.svg)](https://protogrid.dev/servers/com.edgethirteen.www/pumpcheck)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (1)

- `check_npm_download_trust`: Check whether an npm package's public download count reflects real adoption. Detects 'download pumping' -- the documented supply-chain technique where a package is published in hundreds of rapid-fire versions so registry mirrors and security scanners inflate its download counter, making an unused or malicious package look popular. Returns npm's headline 30-day count, a spike-resistant estimate of sustained real usage, the share of the month falling on the busiest single day, recent version-flood bursts, and a verdict of clean, unreliable or inflated. Use before adding or recommending a dependency, especially a new or unfamiliar one. This free check does one package per call; auditing a whole package.json or package-lock.json in one pass is a separate $299 product at https://www.edgethirteen.com/tools/pumpcheck.
