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

  pass25% of grade

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

  Python build script has no build-time network/exec; repository linkage verified

• 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. scripts/check_distribution_status.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

  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 (scripts/check_distribution_status.py: subprocess.* call; src/fantasy_football_manager/dashboard_static/assets/index-BoETzFEl.js: outbound HTTP/socket call). has both shell/exec and destructive filesystem writes (scripts/check_distribution_status.py: subprocess.* call; deployment/backup.py: destructive filesystem call (shutil.rmtree/os.remove/etc.)). discloses shell/exec capability: scripts/check_distribution_status.py: subprocess.* call discloses shell/exec capability: scripts/install_local_plugin.py: subprocess.* call discloses shell/exec capability: src/fantasy_football_manager/espn_service.py: subprocess.* call discloses broad/destructive filesystem access: deployment/backup.py: destructive filesystem call (shutil.rmtree/os.remove/etc.) discloses broad/destructive filesystem access: src/fantasy_football_manager/espn_http_auth.py: destructive filesystem call (shutil.rmtree/os.remove/etc.) discloses broad/destructive filesystem access: src/fantasy_football_manager/espn_service.py: open(…, 'w'/'a'/'x') write-mode file access 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 0.3.3 (minor bump): new capability primitive(s) in source: child_process, fs-write, http-client, subprocess; new hardcoded outbound host/BCC destination(s): 0.0.0.0, 127.0.0.1, 127.0.0.1.example.com, api.github.com, api.github.com.evil.example, attacker.example, elsewhere.invalid, evil.example, example.com, example.invalid, fantasy.espn.com, fantasy.espn.com.invalid, github.com, glama.ai, lm-api-reads.fantasy.espn.com, lm-api-writes.fantasy.espn.com, name, other.example, playwright.dev, pypi.org, react.dev, registry.modelcontextprotocol.io, user, www.w3.org.

• 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 heartbeat behavior — disclosure
