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).

  tool "relay" param "url" description: names an outbound copy/exfil destination (BCC/exfil verb).

• Supply chain

  warn25% of grade

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

  package name "@agishub/mcp" is edit-distance 2 from popular package "yup" (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/hono" is edit-distance 2 from popular package "pino" (typosquat candidate); dependency "hono" is edit-distance 2 from popular package "pino" (typosquat candidate); dependency "viem" is edit-distance 2 from top-20 package "vue" (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.

  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 2.1.0 (patch bump): tool "now_in" description changed (wording only, no injection pattern); tool "convert_timezone" description changed (wording only, no injection pattern); tool "convert_batch" description changed (wording only, no injection pattern); tool "tz_offset" description changed (wording only, no injection pattern); tool "list_timezones" description changed (wording only, no injection pattern); tool "lookup_timezone" description changed (wording only, no injection pattern); tool "date_math" description changed (wording only, no injection pattern); tool "find_meeting_slots" description changed (wording only, no injection pattern); tool "is_holiday" description changed (wording only, no injection pattern); new tool "extract" touches a sensitive surface (email/exec/net/fs); new tool "qr_code" touches a sensitive surface (email/exec/net/fs); new tool "convert_units" appeared; new tool "convert_currency" appeared; new tool "summarize" touches a sensitive surface (email/exec/net/fs); new tool "classify" appeared; new tool "extract_entities" appeared; new tool "transcribe" touches a sensitive surface (email/exec/net/fs); new tool "embed" appeared; new tool "chat" touches a sensitive surface (email/exec/net/fs); new tool "memory_upsert" appeared; new tool "memory_search" appeared; new tool "relay" touches a sensitive surface (email/exec/net/fs); new tool "status" appeared; new tool "price" appeared; new tool "request_feature" appeared; new tool "shorten" touches a sensitive surface (email/exec/net/fs); new hardcoded outbound host/BCC destination(s): github.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)
