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.

  no resolvable repository linked to the package (provenance unverifiable)

• Credential hygiene

  warn15% of grade

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

  tests/test_advisor.py: assigns a literal to secret (SUPE…NT (len 27)) — non-provider secret literal; prefer environment intake. tests/test_config.py: assigns a literal to token (tkv_…et (len 14)) — non-provider secret literal; prefer environment intake. tests/test_config.py: assigns a literal to token (tkv_…et (len 19)) — non-provider secret literal; prefer environment intake. tests/test_emitter.py: assigns a literal to token (tkv_…AA (len 12)) — non-provider secret literal; prefer environment intake. tests/test_emitter.py: assigns a literal to token (tkv_…BB (len 12)) — non-provider secret literal; prefer environment intake. tests/test_emitter.py: assigns a literal to token (tkv_…me (len 12)) — non-provider secret literal; prefer environment intake. tests/test_gemini_client.py: assigns a literal to api_key (sk-s…ey (len 13)) — non-provider secret literal; prefer environment intake. tests/test_improve.py: assigns a literal to api_key (sk-a…ey (len 14)) — non-provider secret literal; prefer environment intake. tests/test_openai_client.py: assigns a literal to api_key (sk-s…ey (len 13)) — non-provider secret literal; prefer environment intake. Reads secrets from the environment (e.g. src/tokeven/advisor.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 (src/tokeven/guardrails.py: subprocess.* call; src/tokeven/emitter.py: outbound HTTP/socket call). has both shell/exec and destructive filesystem writes (src/tokeven/guardrails.py: subprocess.* call; src/tokeven/emitter.py: destructive filesystem call (shutil.rmtree/os.remove/etc.)). discloses shell/exec capability: src/tokeven/guardrails.py: subprocess.* call discloses shell/exec capability: src/tokeven/status.py: subprocess.* call discloses broad/destructive filesystem access: src/tokeven/emitter.py: destructive filesystem call (shutil.rmtree/os.remove/etc.) 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 0.3.0 (minor bump): new capability primitive(s) in source: fs-write, http-client, subprocess; new hardcoded outbound host/BCC destination(s): 127.0.0.1, api.anthropic.com, api.openai.com, api.tokeven.com, api.x.ai, example.com, generativelanguage.googleapis.com, my-gateway.internal, t, test, tokeven.com, x.

• Transport config

  warn10% of grade

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

  manifest/source references beacon behavior — disclosure
