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).

  resource "Commonlands MCP public connection metadata" description: off-vendor URL in a description (mcp.commonlands.com); capability text should not name where data goes. server instructions: off-vendor URL in a description (mcp.commonlands.com); capability text should not name where data goes.

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

  fail10% of grade

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

  vs prior 0.2.0 (minor bump): tool "calculate_field_of_view" description changed (wording only, no injection pattern); tool "calculate_field_of_view" gained input property(ies): widthPx, heightPx, horizontalPixels, verticalPixels, pixelSizeUm, pixelPitchUm, sensorWidthMm, sensorHeightMm; tool "match_lens_to_sensor" description changed (wording only, no injection pattern); tool "match_lens_to_sensor" gained input property(ies): widthPx, heightPx, horizontalPixels, verticalPixels, pixelSizeUm, pixelPitchUm, sensorWidthMm, sensorHeightMm; tool "create_cart" description changed (wording only, no injection pattern); tool "get_cart" description changed (wording only, no injection pattern); tool "get_cart" gained input property(ies): cart_access_token; tool "update_cart" description changed (wording only, no injection pattern); tool "update_cart" gained input property(ies): cart_access_token; tool "submit_rfq" description changed (wording only, no injection pattern); tool "submit_rfq" gained input property(ies): confirm; new hardcoded outbound host/BCC destination(s): commonlands-camera-components.myshopify.com, commonlands.com, ia97wrz7ag.execute-api.us-west-2.amazonaws.com, mcp.commonlands.com.

• 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)
