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

  fail25% of grade

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

  Python build script executes at build time: network call in build script

• Credential hygiene

  warn15% of grade

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

  frontend/src/components/browser/BrowserViewer.tsx: assigns a literal to password (${vn…d} (len 19)) — non-provider secret literal; prefer environment intake. src/openbrowser/config.py: assigns a literal to api_key (your…re (len 24)) — non-provider secret literal; prefer environment intake. Reads secrets from the environment (e.g. .opencode/plugins/openbrowser.js) — the recommended intake shape.

• Permission scope

  fail15% of grade

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

  HIGH: shell/exec capability AND network egress together — download-and-execute risk (benchmarks/e2e_llm_benchmark.py: subprocess.* call; backend/app/core/auth.py: outbound HTTP/socket call). HIGH: shell/exec capability AND destructive filesystem writes together (benchmarks/e2e_llm_benchmark.py: subprocess.* call; benchmarks/e2e_llm_benchmark.py: open(…, 'w'/'a'/'x') write-mode file access). discloses shell/exec capability: benchmarks/e2e_llm_benchmark.py: subprocess.* call discloses shell/exec capability: benchmarks/e2e_published_test.py: subprocess.* call discloses shell/exec

static analysis sees the primitive is present and reachable, not whether its use is attacker-controlled.

• Version behavior

  unscannable10% of grade

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

  no prior version to diff (first sight of me.openbrowser/[email protected]); version-drift / rug-pull cannot be evaluated. Cold-start risk is covered by point-in-time checks (injection_surface, supply_chain, credential_hygiene), not here.

• Transport config

  fail10% of grade

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

  source performs runtime self-update / download-and-execute (bypasses version_behavior); sends telemetry to third-party SDK (posthog) — disclosure, verify opt-in; manifest/source references telemetry behavior — disclosure
