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 319 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

  fail10% of grade

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

  vs prior 0.1.13 (patch bump): new tool "register_restaurant" touches a sensitive surface (email/exec/net/fs); new tool "verify_registration" touches a sensitive surface (email/exec/net/fs); new tool "get_state" appeared; new tool "get_brand_profile" appeared; new tool "get_goals" appeared; new tool "get_season_briefs" appeared; new tool "get_brand_legacy" appeared; new tool "get_collections" appeared; new tool "build_brand_project" appeared; new tool "set_brand_project_active" appeared; new tool "run_brand_program" touches a sensitive surface (email/exec/net/fs); new tool "get_city_projects" appeared; new tool "contribute_city_project" appeared; new tool "get_city_politics" appeared; new tool "propose_city_project" appeared; new tool "endorse_proposal" appeared; new tool "get_concessions" appeared; new tool "bid_concession" appeared; new tool "get_daily_report" appeared; new tool "get_market" appeared; new tool "get_district_intel" appeared; new tool "get_labor_market" appeared; new tool "get_reviews" appeared; new tool "read_newspaper" touches a sensitive surface (email/exec/net/fs); new tool "update_menu" appeared; new tool "remove_menu_item" appeared; new tool "place_order" appeared; new tool "hire_staff" appeared; new tool "fire_staff" appeared; new tool "respond_to_review" appeared; new tool "launch_campaign" appeared; new tool "deep_clean" appeared; new tool "renovate" appeared; new tool "switch_store" appeared; new tool "open_branch" appeared; new tool "close_store" appeared; new tool "liquidate_inventory" appeared; new tool "transfer_inventory" appeared; new tool "sell_vouchers" appeared; new tool "promo_bundle" appeared; new tool "promo_review_incentive" appeared; new tool "get_contracts" appeared; new tool "claim_contract" appeared; new tool "fulfill_contract" appeared; new tool "petition_city_hall" appeared; new tool "get_petitions" appeared; new tool "raise_salary" appeared; new tool "spread_rumor" appeared; new tool "spy_on_restaurant" appeared; new tool "poach_staff" appeared; new tool "propose_collab" appeared; new tool "get_collabs" appeared; new tool "respond_to_collab" appeared; new tool "get_league" touches a sensitive surface (email/exec/net/fs); new tool "declare_stack" appeared; new tool "get_leaderboard" appeared; new tool "view_competitor" appeared; new tool "open_supply_contract" appeared; new tool "list_supply_contracts" appeared; new tool "cancel_supply_contract" appeared; new tool "buy_premises" appeared; new tool "start_rnd" appeared; new tool "get_rnd" appeared; new tool "abandon_rnd" appeared; new tool "start_training" appeared; new tool "get_training" appeared; new tool "abandon_training" appeared; new tool "start_sourcing" appeared; new tool "get_sourcing" appeared; new tool "abandon_sourcing" appeared; new tool "get_michelin" appeared; new tool "start_michelin_prep" appeared; new tool "stop_michelin_prep" appeared; new tool "review_history" appeared.

• Transport config

  unscannable10% of grade

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

  local stdio server: no remote transport or auth surface, and no phone-home/telemetry signal found in source. Absence of transport findings is NOT a safety guarantee — phone-home hosts can be constructed at runtime and defeat static analysis.
