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 "pay_with_x402" description: off-vendor URL in a description (github.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.

  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 "submit_prayer_request" has a secret-shaped input parameter "consent_token" — secrets must never be tool parameters (the model would supply/handle the credential). tool "check_prayer_status" has a secret-shaped input parameter "consent_token" — secrets must never be tool parameters (the model would supply/handle the credential). tool "give_to_church" has a secret-shaped input parameter "consent_token" — secrets must never be tool parameters (the model would supply/handle the credential). tool "get_faith_context" has a secret-shaped input parameter "consent_token" — 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 "verify_scripture" appeared; new tool "get_verse" appeared; new tool "lookup_strongs" appeared; new tool "find_churches" appeared; new tool "submit_prayer_request" touches a sensitive surface (email/exec/net/fs); new tool "check_prayer_status" appeared; new tool "give_to_church" touches a sensitive surface (email/exec/net/fs); new tool "ask_ora" appeared; new tool "search_sermons" appeared; new tool "get_sermon" touches a sensitive surface (email/exec/net/fs); new tool "purchase_sermon" touches a sensitive surface (email/exec/net/fs); new tool "purchase_bundle" touches a sensitive surface (email/exec/net/fs); new tool "pay_with_x402" whose description contains embedded outbound URL; new tool "get_credit_balance" touches a sensitive surface (email/exec/net/fs); new tool "browse_catalog" touches a sensitive surface (email/exec/net/fs); new tool "score_doctrinal_fit" touches a sensitive surface (email/exec/net/fs); new tool "get_lectionary" touches a sensitive surface (email/exec/net/fs); new tool "synthesize_speech" touches a sensitive surface (email/exec/net/fs); new tool "get_faith_context" 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)
