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: subprocess in build script

• Credential hygiene

  warn15% of grade

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

  src/solidlsp/lsp_protocol_handler/lsp_types.py: assigns a literal to token (Prog…en (len 13)) — non-provider secret literal; prefer environment intake. Reads secrets from the environment (e.g. scripts/build_news_json.py) — the recommended intake shape.

• Permission scope

  fail15% of grade

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

  HIGH: downloads and pipes straight to a shell (src/solidlsp/language_servers/lean4_language_server.py: pipes a download into a shell). has both shell/exec and destructive filesystem writes (repo_dir_sync.py: os.system/os.popen/os.exec* call; repo_dir_sync.py: open(…, 'w'/'a'/'x') write-mode file access). discloses shell/exec capability: 33 files (repo_dir_sync.py, docs/create_toc.py, scripts/build_news_json.py, +30 more) discloses broad/destructive filesystem access: 42 files (repo_dir_sync.py, repo_dir_sync.py, docs/autogen_docs.py, +39 more) Capability DISCLOSURE, not a verdict: static analysis sees the primitive is present and reachable, not whether its use is attacker-controlled.

• Version behavior

  unscannable10% of grade

  Diff of tool definitions between versions; new permissions or changed descriptions in a patch release (the postmark-mcp class).

  no prior version to diff (first sight of io.github.oraios/[email protected]); version-drift / rug-pull cannot be evaluated. Cold-start risk is covered by point-in-time checks (injection_surface, supply_chain, credential_hygiene), not here.

• 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 analytics behavior — disclosure
