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.

  tests/test_cli.py: contains a hardcoded OpenAI API key (sk-a…89 (len 34)) — in an example/sample file; verify it is not a real key. tests/test_http_authority.py: assigns a literal to token (call…en (len 12)) — non-provider secret literal; prefer environment intake. tests/test_http_authority.py: assigns a literal to token (actu…en (len 19)) — non-provider secret literal; prefer environment intake. tests/test_maya_outbox.py: assigns a literal to token (secr…en (len 12)) — non-provider secret literal; prefer environment intake. tests/test_mcp_research_report.py: assigns a literal to token (scop…en (len 12)) — non-provider secret literal; prefer environment intake. tests/test_mcp_v2.py: assigns a literal to token (prot…en (len 15)) — non-provider secret literal; prefer environment intake. tests/test_operational_status.py: assigns a literal to token (dedi…en (len 15)) — non-provider secret literal; prefer environment intake. tests/test_provider_evidence.py: assigns a literal to secret (do-n…ss (len 12)) — non-provider secret literal; prefer environment intake. tests/test_provider_transport_conformance.py: assigns a literal to api_key (prov…et (len 15)) — non-provider secret literal; prefer environment intake. tests/test_research_target_contract.py: embeds a PRIVATE KEY block. (in an example/sample file — lower severity, but a real key here still leaks.) tests/test_transport_parity.py: assigns a literal to token (scop…en (len 12)) — non-provider secret literal; prefer environment intake. Reads secrets from the environment (e.g. argus/acquisition/browser_policy.py) — 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 (argus/config.py: subprocess.* call; argus/acquisition/transport.py: outbound HTTP/socket call). has both shell/exec and destructive filesystem writes (argus/config.py: subprocess.* call; argus/acceptance_v3/bundle.py: destructive filesystem call (shutil.rmtree/os.remove/etc.)). discloses shell/exec capability: 4 files (argus/config.py, argus/extraction/playwright_extractor.py, argus/recovery/evidence.py, +1 more) discloses broad/destructive filesystem access: 8 files (argus/acceptance_v3/bundle.py, argus/acceptance_v3/contract.py, argus/persistence/search_ledger.py, +5 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).

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