## Quality 80/100 (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`: 8 of 8 tools declare readOnlyHint or destructiveHint
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: find_tool (idempotentHint); list_library_books (idempotentHint); get_library_book (idempotentHint); …
- pass `tools.token_cost`: about 840 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 75 (weight 15)

- warn `stability.changes`: 6 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: 8, about 840 tokens to load them all
- tool set hash: e8967d43188a6a9402b82e900167889b
- tools last changed: 2026-10-02T23:14:06.883Z
- badge: [![protogrid quality](https://protogrid.dev/badge/com.aiengineerprofessional/engineerpro-library.svg)](https://protogrid.dev/servers/com.aiengineerprofessional/engineerpro-library)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-10-02 `get_guide_section` added
  - Return the free overview excerpt for a flagship engineering guide plus the apex take-away link and cited source books (EP-204). Optionally supply a section name to get a specific section summary and its grounding citations.
- 2026-09-28 `find_tool` added
  - Substring search across the SE tools catalog and its guide bindings (EP-219: bound step, construct, tension).
- 2026-09-28 `compare_tradeoff` added
  - Return one named engineering tension's opposing camps, a cited answer, and the books it's grounded in (EP-217).
- 2026-09-28 `get_concept` added
  - Return one engineering concept's definition, a cited ≤60-word answer, and the books it's grounded in (EP-217, derived from bicycle-guide's canonical guide bodies).
- 2026-09-26 `list_tools` changed (outputSchema)
- 2026-09-25 `get_membership_offer` removed
  - Returns the AI Engineering chapter of the Bicycle Cooperative membership offer (five options with chapter substitution and join URL).
