## 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: read_post (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); related_posts (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); site_info (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 351 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`: 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: 5, about 351 tokens to load them all
- tool set hash: 0930b5ac58d913dd3120ca5a56789948
- tools last changed: 2026-10-10T01:56:42.559Z
- badge: [![protogrid quality](https://protogrid.dev/badge/dev.mashprime/mashprime.svg)](https://protogrid.dev/servers/dev.mashprime/mashprime)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-10-10 `related_posts` added
  - Posts closest in meaning to a given post, by similarity of their text embeddings, most similar first. Use to follow a thread of ideas from one post to the next.

  - before: Search blog posts by keyword across titles, descriptions, and full text. Returns matching posts with a snippet.
