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

  fail25% of grade

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

  server instructions: URL on a cheap/abused TLD (swapwizard.xyz) — postmark-mcp used giftshop.club. server instructions: URL on a cheap/abused TLD (mcp.swapwizard.xyz) — postmark-mcp used giftshop.club. tool "search_liquidity_pools" description: bare 'IMPORTANT:' prose in a description (tag form is high-confidence; prose is warn). tool "list_user_lp_positions" description: bare 'IMPORTANT:' prose in a description (tag form is high-confidence; prose is warn). tool "zap_into_lp_position" description: bare 'IMPORTANT:' prose in a description (tag form is high-confidence; prose is warn).

• Supply chain

  pass25% of grade

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

  repository linkage verified

• Credential hygiene

  fail15% of grade

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

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

• 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

  unscannable10% of grade

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

  no prior version to diff (first sight of io.github.DeFiRe-business/[email protected]); version-drift / rug-pull cannot be evaluated. Cold-start risk is covered by point-in-time checks (injection_surface, supply_chain, credential_hygiene), not here.

• 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)
