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

  pass25% of grade

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

  Scanned 99 text field(s); no instruction-injection patterns found. PASS = no static red flag. A server can serve different tool descriptions at runtime (the rug-pull class), which static scanning cannot see.

• Supply chain

  warn25% of grade

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

  no resolvable repository linked to the package (provenance unverifiable)

• 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

  unscannable15% of grade

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

  No source files, package.json, or pyproject were fetched; cannot infer capability scope.

• Version behavior

  pass10% of grade

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

  vs prior 2.0.0 (major bump): tool "energy_decision" description changed (wording only, no injection pattern); new tool "buy_dispatch_plan" appeared; new tool "buy_market_brief" appeared; new tool "research" appeared; new tool "articles_id" appeared; new tool "tasks" appeared; new tool "research_post" appeared; new tool "demo_paid_sample" appeared; new tool "research_quick" appeared; new tool "articles_id_post" appeared; new tool "tasks_post" appeared; new tool "price_spot" appeared; new tool "price_forecast" appeared; new tool "carbon_now" appeared; new tool "grid_load" appeared; new tool "renewable_share" appeared; new tool "flexibility_window" appeared; new tool "signals_buy_sell" appeared; new tool "bundle_trading" touches a sensitive surface (email/exec/net/fs); new tool "history_prices" appeared; new tool "history_prices_stats" appeared; new tool "subscribe_price_alert" appeared; new tool "subscribe_co2_low" appeared; new tool "optimizer_cheapest_window" appeared; new tool "price_negative_forecast" appeared; new tool "predict_negative_price" appeared; new tool "summary_today" appeared; new tool "region" appeared; new tool "events_grid" appeared. Low-severity drift (informational; consistent with the version bump).

• 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)
