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_ai_analysis_service.py: assigns a literal to api_key ($OPE…EY (len 15)) — non-provider secret literal; prefer environment intake. tests/test_ai_analysis_service.py: assigns a literal to api_key ($ANT…EY (len 14)) — non-provider secret literal; prefer environment intake. tests/test_ai_analysis_service.py: assigns a literal to api_key (gemi…ey (len 14)) — non-provider secret literal; prefer environment intake. tests/test_ai_analysis_service.py: assigns a literal to api_key (secr…ey (len 17)) — non-provider secret literal; prefer environment intake. tests/test_ai_analysis_service.py: assigns a literal to api_key ($GEM…EY (len 15)) — non-provider secret literal; prefer environment intake. tests/test_bw_resolver.py: embeds a PRIVATE KEY block. (in an example/sample file — lower severity, but a real key here still leaks.) tests/test_cli_ssh.py: embeds a PRIVATE KEY block. (in an example/sample file — lower severity, but a real key here still leaks.) tests/test_config_sync_service.py: assigns a literal to api_key (sk-s…ey (len 13)) — non-provider secret literal; prefer environment intake. tests/test_ephemeral_key.py: embeds a PRIVATE KEY block. (in an example/sample file — lower severity, but a real key here still leaks.) tests/test_incident_response_tools.py: assigns a literal to password ({_SE…W} (len 12)) — non-provider secret literal; prefer environment intake. tests/test_relay_log.py: assigns a literal to token (secr…ue (len 12)) — non-provider secret literal; prefer environment intake. Reads secrets from the environment (e.g. scripts/demo_fleet.py) — the recommended intake shape.

• Permission scope

  warn15% of grade

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

  references credential paths: 11 files (src/servonaut/cli/hetzner.py, src/servonaut/cli/ssh.py, src/servonaut/screens/aws_create.py, +8 more) has both shell/exec and network egress — capable of download-and-run, though no such path was observed (src/servonaut/main.py: subprocess.* call; src/servonaut/mcp/remote_client.py: outbound HTTP/socket call). has both shell/exec and destructive filesystem writes (src/servonaut/main.py: subprocess.* call; src/servonaut/config/manager.py: destructive filesystem call (shutil.rmtree/os.remove/etc.)). discloses shell/exec capability: 17 files (src/servonaut/main.py, src/servonaut/cli/memory.py, src/servonaut/cli/secrets.py, +14 more) discloses broad/destructive filesystem access: 17 files (src/servonaut/config/manager.py, src/servonaut/mcp/audit.py, src/servonaut/screens/server_actions.py, +14 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).

• Transport config

  warn10% of grade

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