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).

  tool "deep_research" description: off-vendor URL in a description (pipeworx.io); capability text should not name where data goes. tool "subscribe" param "delivery" description: off-vendor URL in a description (pipeworx.io); capability text should not name where data goes. tool "subscribe" param "delivery" description: off-vendor URL in a description (...); capability text should not name where data goes. tool "bet_research" param "market" description: off-vendor URL in a description (polymarket.com); capability text should not name where data goes. tool "generate_llms_txt" param "url" description: off-vendor URL in a description (example.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 "ai_visibility_check" has a secret-shaped input parameter "_apiKey" — secrets must never be tool parameters (the model would supply/handle the credential). tool "scan_competitor_ai_presence" has a secret-shaped input parameter "_apiKey" — 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 0.1.0 (patch bump): new tool "ask_pipeworx" appeared; new tool "ask_pipeworx_beta" appeared; new tool "ask_pipeworx_grounded" appeared; new tool "search_within" touches a sensitive surface (email/exec/net/fs); new tool "deep_research" whose description contains embedded outbound URL; new tool "discover_tools" appeared; new tool "resolve_entity" appeared; new tool "compare_entities" appeared; new tool "subscribe" touches a sensitive surface (email/exec/net/fs); new tool "unsubscribe" appeared; new tool "list_subscriptions" appeared; new tool "recent_alerts" touches a sensitive surface (email/exec/net/fs); new tool "entity_profile" appeared; new tool "recent_changes" appeared; new tool "validate_claim" appeared; new tool "scan_dependency" appeared; new tool "bet_research" touches a sensitive surface (email/exec/net/fs); new tool "polymarket_arbitrage" appeared; new tool "polymarket_edges" touches a sensitive surface (email/exec/net/fs); new tool "polymarket_kalshi_spread" touches a sensitive surface (email/exec/net/fs); new tool "polymarket_fill_risk" touches a sensitive surface (email/exec/net/fs); new tool "polymarket_edge_tracker" appeared; new tool "pipeworx_trending" appeared; new tool "suggest_questions" appeared; new tool "generate_llms_txt" touches a sensitive surface (email/exec/net/fs); new tool "ai_visibility_check" touches a sensitive surface (email/exec/net/fs); new tool "scan_competitor_ai_presence" appeared; new tool "pipeworx_feedback" appeared; new tool "remember" touches a sensitive surface (email/exec/net/fs); new tool "recall" touches a sensitive surface (email/exec/net/fs); new tool "forget" touches a sensitive surface (email/exec/net/fs); new tool "search_events" appeared; new tool "event" appeared; new tool "categories" appeared.

• 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)
