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

  warn25% of grade

  Tool descriptions/manifest scanned for instruction-injection patterns (imperatives at the model, hidden text, 'ignore previous', data-exfil URLs).

  tool "sheet_context" description: cross-tool redirection ('instead of call…').

• Supply chain

  warn25% of grade

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

  dependency "jsts" is edit-distance 2 from popular package "jest" (typosquat candidate)

• Credential hygiene

  pass15% of grade

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

  No hardcoded secrets, secret-shaped tool parameters, or leaked keys found. PASS = no static red flag; static analysis cannot prove the code honors env-based secret handling at runtime.

• Permission scope

  pass15% of grade

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

  No shell-exec, unbounded/sensitive filesystem, or download-and-run primitives found in scanned source. PASS = no static red flag. Static scanning is blind to code fetched or executed at runtime.

• 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 0.9.73 (patch bump): new tool "load_plan" touches a sensitive surface (email/exec/net/fs); new tool "sheet_info" appeared; new tool "set_scale" touches a sensitive surface (email/exec/net/fs); new tool "propose_takeoff" appeared; new tool "measure_polygon" appeared; new tool "cut_out" touches a sensitive surface (email/exec/net/fs); new tool "measure_line" appeared; new tool "measure_surface" touches a sensitive surface (email/exec/net/fs); new tool "place_count" appeared; new tool "symbol_sweep" touches a sensitive surface (email/exec/net/fs); new tool "sweep_schedule_row" touches a sensitive surface (email/exec/net/fs); new tool "count_marks" touches a sensitive surface (email/exec/net/fs); new tool "derive_base" appeared; new tool "derive_transitions" touches a sensitive surface (email/exec/net/fs); new tool "takeoff_summary" appeared; new tool "export_takeoff" touches a sensitive surface (email/exec/net/fs); new tool "export_dxf" touches a sensitive surface (email/exec/net/fs); new tool "export_report" touches a sensitive surface (email/exec/net/fs); new tool "import_takeoff" touches a sensitive surface (email/exec/net/fs); new tool "apply_rules" touches a sensitive surface (email/exec/net/fs); new tool "export_marked_pdf" touches a sensitive surface (email/exec/net/fs); new tool "list_shapes" touches a sensitive surface (email/exec/net/fs); new tool "delete_shape" touches a sensitive surface (email/exec/net/fs); new tool "scope_duplicates" touches a sensitive surface (email/exec/net/fs); new tool "scope_merge" touches a sensitive surface (email/exec/net/fs); new tool "revise_proposal" appeared; new tool "withdraw_proposal" touches a sensitive surface (email/exec/net/fs); new tool "sheet_context" touches a sensitive surface (email/exec/net/fs); new tool "get_sheet_vectors" touches a sensitive surface (email/exec/net/fs); new tool "edit_shape" touches a sensitive surface (email/exec/net/fs); new tool "edit_materials" touches a sensitive surface (email/exec/net/fs); new tool "edit_condition" appeared; new tool "propose_condition_edit" touches a sensitive surface (email/exec/net/fs); new tool "withdraw_condition_edit" appeared; new tool "duplicate_condition" appeared; new tool "split_condition" appeared; new tool "undo_last" touches a sensitive surface (email/exec/net/fs); new tool "sheet_graph" touches a sensitive surface (email/exec/net/fs); new tool "resolve_tag" appeared; new tool "find_schedule" touches a sensitive surface (email/exec/net/fs); new tool "read_sheet_text" touches a sensitive surface (email/exec/net/fs); new tool "find_text" touches a sensitive surface (email/exec/net/fs); new tool "view_sheet" touches a sensitive surface (email/exec/net/fs); new tool "annotate" appeared; new tool "list_annotations" touches a sensitive surface (email/exec/net/fs); new tool "link_annotation" appeared; new tool "mark_verdict" touches a sensitive surface (email/exec/net/fs); new tool "delete_verdict" touches a sensitive surface (email/exec/net/fs); new tool "create_rfi" appeared; new tool "list_rfis" touches a sensitive surface (email/exec/net/fs); new tool "resolve_rfi" appeared; new tool "delete_rfi" touches a sensitive surface (email/exec/net/fs).

• Transport config

  unscannable10% of grade

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

  local stdio server: no remote transport or auth surface, and no phone-home/telemetry signal found in source. Absence of transport findings is NOT a safety guarantee — phone-home hosts can be constructed at runtime and defeat static analysis.
