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

  warn25% of grade

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

  tool "get_job" param "url" description: off-vendor URL in a description (hirejack.com); capability text should not name where data goes. tool "match_job" param "url" description: off-vendor URL in a description (hirejack.com); capability text should not name where data goes.

• Supply chain

  warn25% of grade

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

  package name "@hirejack/mcp" is edit-distance 2 from popular package "yup" (typosquat candidate)

• 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

  fail10% of grade

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

  vs prior 0.3.9 (patch bump): new tool "search_jobs" touches a sensitive surface (email/exec/net/fs); new tool "get_job" touches a sensitive surface (email/exec/net/fs); new tool "get_company_profile" touches a sensitive surface (email/exec/net/fs); new tool "search_companies" appeared; new tool "get_market_pulse" appeared; new tool "match_job" appeared; new tool "company_fit" appeared; new tool "recommendations" appeared; new tool "salary_benchmark" appeared; new tool "skill_gap" appeared; new tool "market_position" appeared; new tool "skill_impact" appeared; new tool "watchlist_intelligence" appeared; new tool "resume_rewrite" appeared; new tool "interview_prep" touches a sensitive surface (email/exec/net/fs); new tool "get_company_history" appeared; new tool "get_skill_history" appeared; new tool "get_market_history" appeared; new tool "compare_companies" appeared; new tool "find_companies" appeared; new tool "find_breakout_companies" appeared; new tool "find_emerging_skills" appeared; new tool "find_emerging_roles" appeared; new tool "save_job" appeared; new tool "watch_company" appeared; new tool "track_application" appeared; new tool "list_saved_jobs" touches a sensitive surface (email/exec/net/fs); new tool "list_applications" touches a sensitive surface (email/exec/net/fs); new tool "list_watchlist" touches a sensitive surface (email/exec/net/fs); new tool "get_profile" touches a sensitive surface (email/exec/net/fs); new tool "update_preferences" 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://hirejack.com/api/mcp" uses TLS (https); remote endpoint uses OAuth (strongest auth mode)
