What we checked

Six static checks, weighted by risk. Every result reflects only what could be observed in the published package and repository — never intent.

• Injection surface

  pass25% of grade

  Tool descriptions/manifest scanned for instruction-injection patterns (imperatives at the model, hidden text, 'ignore previous', data-exfil URLs).

  Scanned 99 text field(s); no instruction-injection patterns found. PASS = no static red flag. A server can serve different tool descriptions at runtime (the rug-pull class), which static scanning cannot see.

• Supply chain

  pass25% of grade

  Package provenance: namespace verification, repo linkage, maintainer count, account age, postinstall scripts, typosquat distance.

  repository linkage verified

• Credential hygiene

  pass15% of grade

  How the server takes secrets (env vs plaintext config vs hardcoded); secrets appearing in tool schemas.

  No hardcoded secrets, secret-shaped tool parameters, or leaked keys found. PASS = no static red flag; static analysis cannot prove the code honors env-based secret handling at runtime.

• Permission scope

  pass15% of grade

  Declared tools vs. breadth (filesystem, network, exec); flags shell-exec and unbounded filesystem access.

  No shell-exec, unbounded/sensitive filesystem, or download-and-run primitives found in scanned source. PASS = no static red flag. Static scanning is blind to code fetched or executed at runtime.

• Version behavior

  warn10% of grade

  Diff of tool definitions between versions; new permissions or changed descriptions in a patch release (the postmark-mcp class).

  vs prior 1.1.0 (minor bump): new tool "get_briefing" touches a sensitive surface (email/exec/net/fs); new tool "track_story" appeared; new tool "get_location_news" appeared; new tool "compare_locations" appeared; new tool "get_source_view" appeared; new tool "find_stories" touches a sensitive surface (email/exec/net/fs); new tool "get_article" touches a sensitive surface (email/exec/net/fs); new tool "list_categories" appeared; new tool "list_sources" appeared; new tool "get_stats" appeared; new tool "get_my_feed" appeared; new tool "get_trending_analytics" appeared; new tool "detect_surge" appeared; new tool "get_content_analytics" appeared; new tool "trigger_enrichment" touches a sensitive surface (email/exec/net/fs); new tool "drain_enrichment_backlog" appeared.

• Transport config

  pass10% of grade

  Remote servers: TLS and auth mode (none/token/OAuth). Local servers: whether the manifest indicates it phones home.

  remote endpoint "https://news.mukoko.com/mcp" uses TLS (https); remote endpoint "https://news.mukoko.dev/mcp" uses TLS (https); remote endpoint uses OAuth (strongest auth mode)
