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

  unscannable25% of grade

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

  No tool descriptions, server instructions, prompts, or resources were fetched; nothing to scan for injection.

• Supply chain

  warn25% of grade

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

  install hook "postinstall" present and not a recognized benign build command; dependency "@bnb-chain/mpp" is edit-distance 2 from popular package "pm2" (typosquat candidate); dependency "@ethereum-attestation-service/eas-sdk" is edit-distance 2 from popular package "aws-sdk" (typosquat candidate); dependency "@ffmpeg/util" is edit-distance 2 from top-20 package "uuid" (typosquat candidate); dependency "@gltf-transform/core" is edit-distance 1 from popular package "cors" (typosquat candidate); dependency "@jaames/iro" is edit-distance 2 from popular package "pino" (typosquat candidate); dependency "@jup-ag/api" is edit-distance 2 from popular package "pg" (typosquat candidate); dependency "@metaplex-foundation/umi" is edit-distance 2 from top-20 package "uuid" (typosquat candidate); dependency "@octokit/rest" is edit-distance 1 from popular package "jest" (typosquat candidate); dependency "@solana-program/token" is edit-distance 2 from popular package "boxen" (typosquat candidate); dependency "@solana/kit" is edit-distance 2 from popular package "vite" (typosquat candidate); dependency "@solana/pay" is edit-distance 2 from popular package "pm2" (typosquat candidate); dependency "@upstash/redis" is edit-distance 2 from popular package "redux" (typosquat candidate); dependency "@vercel/og" is edit-distance 1 from popular package "pg" (typosquat candidate); dependency "@x402/core" is edit-distance 1 from popular package "cors" (typosquat candidate); dependency "@x402/evm" is edit-distance 2 from popular package "ejs" (typosquat candidate); dependency "@x402/mcp" is edit-distance 2 from popular package "yup" (typosquat candidate); dependency "@x402/svm" is edit-distance 2 from popular package "@anthropic-ai/sdk" (typosquat candidate); dependency "ai" is edit-distance 2 from popular package "chai" (typosquat candidate); dependency "bn.js" is edit-distance 2 from popular package "ejs" (typosquat candidate); dependency "cborg" is edit-distance 2 from popular package "@babel/core" (typosquat candidate); dependency "jose" is edit-distance 2 from popular package "@babel/core" (typosquat candidate); dependency "sas-lib" is edit-distance 2 from top-20 package "tslib" (typosquat candidate); dependency "viem" is edit-distance 2 from top-20 package "vue" (typosquat candidate)

• Credential hygiene

  warn15% of grade

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

  .env.example: embeds a PRIVATE KEY block. (in an example/sample file — lower severity, but a real key here still leaks.)

• Permission scope

  pass15% of grade

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

  Network egress present (package.json depends on HTTP client "axios") — expected for most servers and not a finding on its own. 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.nirholas/[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

  warn10% of grade

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

  manifest/source references analytics behavior — disclosure
