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_embeddings.py: assigns a literal to api_key (expl…ey (len 12)) — non-provider secret literal; prefer environment intake. Reads secrets from the environment (e.g. hooks/stale-graph-check.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 (hooks/branch-sync-check.py: subprocess.* call; src/better_code_review_graph/relay_setup.py: outbound HTTP/socket call). discloses shell/exec capability: 6 files (hooks/branch-sync-check.py, scripts/preserve-diacritics.py, src/better_code_review_graph/federation.py, +3 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).

  vs prior 3.23.0 (minor bump): new capability primitive(s) in source: dynamic-eval, http-client, subprocess; new hardcoded outbound host/BCC destination(s): 127.0.0.1, aistudio.google.com, better-code-review-graph.n24q02m.dev, cloud.google.com, crg.example, crg.example.com, crg.example.test, dashboard.cohere.com, docs.cohere.com, env-embed, env-llm, example.com, gateway.example, github.com, graphml.graphdrawing.org, gw-a, gw-b, jina.ai, json.schemastore.org, maven.apache.org, platform.openai.com, proxy.example, relay.example.com.

• 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
