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.

  dependency "node-cron" is edit-distance 2 from popular package "nodemon" (typosquat candidate); dependency "@remotion/cli" is edit-distance 2 from popular package "chai" (typosquat candidate); dependency "@prisma/client" is edit-distance 2 from popular package "@aws-sdk/client-s3" (typosquat candidate)

• Credential hygiene

  warn15% of grade

  How the server takes secrets (env vs plaintext config vs hardcoded); secrets appearing in tool schemas.

  src/advancedSettings.js: assigns a literal to password (http…rd (len 31)) — non-provider secret literal; prefer environment intake. Reads secrets from the environment (e.g. src/workflows/actions.js) — the recommended intake shape.

• Permission scope

  warn15% of grade

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

  has both shell/exec and network egress — capable of download-and-run, though no such path was observed (src/plugins/manager.js: imports child_process and calls exec/spawn; src/accountMisc.js: outbound HTTP/socket call). has both shell/exec and destructive filesystem writes (src/plugins/manager.js: imports child_process and calls exec/spawn; src/a2a/auth.js: destructive/writing fs.* call (write/unlink/rm/chmod/rename)). discloses shell/exec capability: src/plugins/manager.js: imports child_process and calls exec/spawn discloses shell/exec capability: src/scheduler/scheduler.js: imports child_process and calls exec/spawn discloses dynamic code execution: 9 files (src/agents/browserDriver.js, src/scrapers/adapters/crawlee.js, src/engagementManager.js, +6 more) discloses broad/destructive filesystem access: 21 files (src/a2a/auth.js, src/scrapers/twitter/http/auth.js, src/agents/browserDriver.js, +18 more) Capability DISCLOSURE, not a verdict: static analysis sees the primitive is present and reachable, not whether its use is attacker-controlled.

• 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 3.4.4 (minor bump): new capability primitive(s) in source: child_process, dynamic-eval, fs-write, http-client; new hardcoded outbound host/BCC destination(s): 0.0.0.0, abs.twimg.com, ads.x.com, agent.xactions.app, api.coingecko.com, api.geckoterminal.com, api.openai.com, api.qrserver.com, api.telegram.org, api.x.com, api.xactions.app, bsky.app, bsky.social, business.x.com, cdn.bsky.app, cdn.jsdelivr.net, developer.x.com, docs.google.com, faucet.circle.com, gexf.net, github.com, help.x.com, httpbin.org, mastodon.social, openrouter.ai, pro.x.com, public.api.bsky.app, publish.twitter.com, studio.x.com, translate.google.com, tweetpik.com, twitsave.com, upload.x.com, www.googleapis.com, www.threads.net, x.com, x402.org, xactions.app, yoursite.com.

• Transport config

  warn10% of grade

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