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 137 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

  pass10% of grade

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

  vs prior 2.0.1 (major bump): new tool "add_idea" appeared; new tool "list_objectives" appeared; new tool "get_matrix_summary" touches a sensitive surface (email/exec/net/fs); new tool "update_element_status" appeared; new tool "search_ideas" appeared; new tool "get_matrix_completeness" appeared; new tool "get_matrix_data" appeared; new tool "share_matrix" touches a sensitive surface (email/exec/net/fs); new tool "get_management_architecture" appeared; new tool "diagnose_theme_deployment" appeared; new tool "suggest_meeting_for_topic" appeared; new tool "create_matrix" appeared; new tool "upsert_element" appeared; new tool "set_correlation" appeared. Low-severity drift (informational; consistent with the version bump).

• 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://hoshin.app/mcp" uses TLS (https); remote endpoint uses OAuth (strongest auth mode)
