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. tests/test_smoke_eval.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.

  discloses dynamic code execution: src/contextweaver/eval/context.py: uses eval()/exec() 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 0.15.0 (minor bump): new capability primitive(s) in source: dynamic-eval, fs-write, subprocess; new hardcoded outbound host/BCC destination(s): ai.pydantic.dev, dgenio.github.io, docs.agno.com, docs.crewai.com, docs.mem0.ai, docs.test.org, example.com, github.com, gofastmcp.com, huggingface.co, json-schema.org, langchain-ai.github.io, maketocreate.com, modelcontextprotocol.io, rich.readthedocs.io, typer.tiangolo.com, www.getzep.com, www.sbert.net.

• 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 Telemetry behavior — disclosure
