## Quality 73/100 (needs work)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-06-18; 2026-07-28 not supported, older versions are deprecated until 2027-07-28

### tool hygiene: 57 (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: CARBON (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); PTV (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); MtoV (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- fail `tools.token_cost`: about 27,082 tokens to load every tool, a large share of an agent's context
- 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: 60, about 27,082 tokens to load them all
- tool set hash: bf83ca275a93901f0b3f9aa864a5e478
- tools last changed: 2026-10-11T19:59:06.747Z
- badge: [![protogrid quality](https://protogrid.dev/badge/com.engscript/mcp.svg)](https://protogrid.dev/servers/com.engscript/mcp)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.
