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

  pass15% of grade

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

  Reads secrets from the environment (e.g. src/finops/accounts.py) — the recommended intake shape. PASS = no static red flag; static analysis cannot prove the code honors env-based secret handling at runtime.

• Permission scope

  fail15% of grade

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

  HIGH: src/finops/setup_wizard.py reads a credential path, executes commands, and makes network calls in the same file — the combination that makes exfiltration possible. references credential paths: src/finops/setup_wizard.py: references a credential path (.aws/credentials) references credential paths: src/finops/setup/cloud_infra.py: references a credential path (.aws/credentials) has both shell/exec and network egress — capable of download-and-run, though no such path was observed (src/finops/setup_wizard.py: subprocess.* call; src/finops/doctor.py: outbound HTTP/socket call). has both shell/exec and destructive filesystem writes (src/finops/setup_wizard.py: subprocess.* call; src/finops/setup_wizard.py: open(…, 'w'/'a'/'x') write-mode file access). discloses shell/exec capability: 7 files (src/finops/setup_wizard.py, src/finops/connectors/terraform.py, src/finops/connectors/terraform_estimate.py, +4 more) discloses broad/destructive filesystem access: 4 files (src/finops/setup_wizard.py, src/finops/analytics/benchmarks.py, src/finops/cleanup/actions.py, +1 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.

  sends telemetry to third-party SDK (Datadog) — disclosure, verify opt-in; manifest/source references telemetry behavior — disclosure
