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. omni/clients/external/github_ops_client.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 (omni/builders/codecraft/rosetta_archaeologist.py: subprocess.* call; omni/clients/internal/communications_client.py: outbound HTTP/socket call). has both shell/exec and destructive filesystem writes (omni/builders/codecraft/rosetta_archaeologist.py: subprocess.* call; omni/lib/io.py: open(…, 'w'/'a'/'x') write-mode file access). discloses shell/exec capability: 10 files (omni/builders/codecraft/rosetta_archaeologist.py, omni/builders/commit_history_builder.py, omni/builders/registry_builder.py, +7 more) discloses broad/destructive filesystem access: omni/lib/io.py: open(…, 'w'/'a'/'x') write-mode file access discloses broad/destructive filesystem access: omni/scanners/polyglot/package_scanner.py: recursive glob ('**') from a broad root 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 0.7.2 (patch bump): new capability primitive(s) in source: fs-write, http-client, subprocess; new hardcoded outbound host/BCC destination(s): 127.0.0.1, github.com, img.shields.io.

• Transport config

  fail10% of grade

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

  source performs runtime self-update / download-and-execute (bypasses version_behavior); manifest/source references tracking behavior — disclosure
