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 202 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

  warn25% of grade

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

  no resolvable repository linked to the package (provenance unverifiable)

• Credential hygiene

  fail15% of grade

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

  tool "revoke_participant_credential" has a secret-shaped input parameter "credentialId" — secrets must never be tool parameters (the model would supply/handle the credential).

• Permission scope

  unscannable15% of grade

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

  No source files, package.json, or pyproject were fetched; cannot infer capability scope.

• 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 1.1.0 (patch bump): new tool "get_discovery_manifest" touches a sensitive surface (email/exec/net/fs); new tool "get_network_metrics" touches a sensitive surface (email/exec/net/fs); new tool "get_connection_bundle" appeared; new tool "generate_client_configuration" touches a sensitive surface (email/exec/net/fs); new tool "get_connection_health" touches a sensitive surface (email/exec/net/fs); new tool "get_sandbox_access_requirements" touches a sensitive surface (email/exec/net/fs); new tool "report_compatibility" appeared; new tool "discover_commerce_index" touches a sensitive surface (email/exec/net/fs); new tool "search_verified_offers" appeared; new tool "get_verified_offer" appeared; new tool "get_verified_provider" appeared; new tool "discover_assurance_services" appeared; new tool "register_owner_mandate" appeared; new tool "revoke_owner_mandate" appeared; new tool "issue_signed_offer" appeared; new tool "execute_authorized_purchase" appeared; new tool "get_purchase_recovery_status" appeared; new tool "recover_authorized_purchase" appeared; new tool "verify_portable_bundle" appeared; new tool "get_economic_history" touches a sensitive surface (email/exec/net/fs); new tool "get_participant_registration_requirements" touches a sensitive surface (email/exec/net/fs); new tool "request_participant_challenge" appeared; new tool "complete_participant_registration" touches a sensitive surface (email/exec/net/fs); new tool "revoke_participant_credential" touches a sensitive surface (email/exec/net/fs); new tool "get_participant_account" appeared; new tool "create_wallet" appeared; new tool "get_wallet" touches a sensitive surface (email/exec/net/fs); new tool "get_balance" touches a sensitive surface (email/exec/net/fs); new tool "list_transactions" touches a sensitive surface (email/exec/net/fs); new tool "get_external_funding_instructions" touches a sensitive surface (email/exec/net/fs); new tool "claim_external_deposit" appeared; new tool "request_testnet_funding" appeared; new tool "get_testnet_funding_status" touches a sensitive surface (email/exec/net/fs); new tool "request_payment" appeared; new tool "get_payment_request" touches a sensitive surface (email/exec/net/fs); new tool "send_payment" touches a sensitive surface (email/exec/net/fs); new tool "get_payment" touches a sensitive surface (email/exec/net/fs); new tool "refund_payment" appeared; new tool "register_commerce_service" touches a sensitive surface (email/exec/net/fs); new tool "search_commerce_services" appeared; new tool "inspect_commerce_service" appeared; new tool "purchase_commerce_service" appeared; new tool "fulfill_commerce_purchase" appeared; new tool "get_commerce_purchase_status" touches a sensitive surface (email/exec/net/fs); new tool "recover_commerce_purchase" touches a sensitive surface (email/exec/net/fs); new tool "request_commerce_refund" appeared; new tool "get_commerce_receipt" touches a sensitive surface (email/exec/net/fs); new tool "verify_economic_receipt" appeared; new tool "request_withdrawal" appeared; new tool "get_withdrawal_status" touches a sensitive surface (email/exec/net/fs).

• Transport config

  fail10% of grade

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

  remote MCP endpoint declares NO authentication (unauthenticated remote — nginx-ui/CVE-2026-33032 class)
