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.

  package name "@sidebutton/server" is edit-distance 1 from popular package "semver" (typosquat candidate); dependency "@sentry/node" is edit-distance 2 from popular package "@babel/core" (typosquat candidate); dependency "@fastify/cors" is edit-distance 1 from popular package "@babel/core" (typosquat candidate); dependency "@sidebutton/core" is edit-distance 1 from popular package "cors" (typosquat candidate)

• 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.

  Network egress present (dashboard/assets/index-BXbktGRP.js: outbound HTTP/socket call) — 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

  fail10% of grade

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

  vs prior 1.1.1 (minor bump): new capability primitive(s) in source: child_process, http-client; new hardcoded outbound host/BCC destination(s): api.anthropic.com, api.openai.com, docs.sentry.io, github.com, sentry.io, sidebutton.com, svelte.dev, www.w3.org.

• Transport config

  warn10% of grade

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

  sends telemetry to third-party SDK (sentry.io) — disclosure, verify opt-in; manifest/source references analytics behavior — disclosure
