- liveness: 96
- freshness: 100

## Quality 96/100 (strong)

### protocol: 88 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session
- pass `protocol.transport`: streamable HTTP
- warn `protocol.list_ttl`: tools/list declares ttlMs 0, so clients re-fetch it on every use

### 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: 100 (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
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 945 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: 8, about 945 tokens to load them all
- tool set hash: 388f597b3020d63ab67a6ace75707339
- tools last changed: 2026-10-01T05:32:24.125Z
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.underwriter-MRX/mrx-mcp.svg)](https://protogrid.dev/servers/io.github.underwriter-MRX/mrx-mcp)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

    Return source text, attribution and dates when available; never infer a review.

- `mrx_list_public_pages`: Discover current public pages, including website journeys and AI guide profiles.
    Categories: all, articles (blog paths), ai_guides, website. Pass content_revision
    on subsequent pages to detect a changing inventory. Read a page before citing it.
    
- `mrx_read_page`: Read one canonical public MRX page after sitemap, hash and indexability checks.
    Accepts only https://mineralrightsxchange.com/ URLs returned by search.
    Private routes, off-site URLs, queries, fragments and redirects are rejected.
    
- `mrx_search_guides`: Search verified public MRX titles, headings and article text.
    Optional jurisdiction/topic filters are source-text matches, not legal conclusions.
    Coverage reports omissions. Do not include personal data in a research query.
