## Trust

- hygiene: 100
- liveness: 100
- freshness: 85

- 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: find_alternative (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); find_manufacturer (readOnlyHint, destructiveHint, idempotentHint, openWorldHint)
- pass `tools.token_cost`: about 579 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: 2, about 579 tokens to load them all
- tool set hash: 09eab59a22d48c78b0f28f6d0c91a340
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.pawel-kowalczyk/harness-atlas.svg)](https://protogrid.dev/servers/io.github.pawel-kowalczyk/harness-atlas)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (2)

- `find_alternative`: Cross-reference a wire-harness component part number (connectors, terminals, seals, cable protection) against the XrefBase equivalence graph. Results are grouped by how strong the relationship is, and the groups are not interchangeable: `verified_replacements` are corroborated drop-in or manufacturer-superseded parts; `functional_equivalents` do the same job but need engineering review; `same_series` and `variants` are the same family in a different configuration and are NOT substitutes; `mates_with` is the counterpart connector the part plugs into, which is specifically not a substitute for it. Every claim carries a confidence level and, where one exists, a public source URL.
- `find_manufacturer`: Search the Harness Atlas directory of wire-harness and cable-assembly manufacturers. Filter by country, industry served, process capability, or name. Returns listed manufacturer profiles (location, website, industries, capabilities).
