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

  pass25% of grade

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

  Scanned 265 text field(s); no instruction-injection patterns found. PASS = no static red flag. A server can serve different tool descriptions at runtime (the rug-pull class), which static scanning cannot see.

• Supply chain

  pass25% of grade

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

  repository linkage verified

• 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 1.1.0 (patch bump): new tool "list_properties" appeared; new tool "get_property" appeared; new tool "list_incomes" appeared; new tool "get_income" appeared; new tool "list_expenses" appeared; new tool "get_expense" appeared; new tool "list_loans" appeared; new tool "get_loan" appeared; new tool "get_loan_schedule" appeared; new tool "list_fiscal_years" appeared; new tool "get_fiscal_year" appeared; new tool "list_furniture" appeared; new tool "list_property_works" appeared; new tool "list_property_components" appeared; new tool "get_onboarding_status" appeared; new tool "get_dashboard_summary" appeared; new tool "create_income" appeared; new tool "update_income" appeared; new tool "create_expense" appeared; new tool "update_expense" appeared; new tool "create_furniture" appeared; new tool "update_furniture" appeared; new tool "create_property_work" appeared; new tool "update_property_work" appeared; new tool "attach_document" touches a sensitive surface (email/exec/net/fs); new tool "compute_depreciation" appeared; new tool "estimate_market_value" appeared; new tool "compute_fiscal_year" appeared; new tool "compare_micro_bic" appeared; new tool "compute_loan_schedule" appeared; new tool "compute_tva" appeared; new tool "generate_fec" appeared; new tool "generate_tax_return" appeared; new tool "create_property" appeared; new tool "update_property" appeared; new tool "delete_income" touches a sensitive surface (email/exec/net/fs); new tool "delete_expense" touches a sensitive surface (email/exec/net/fs); new tool "delete_furniture" touches a sensitive surface (email/exec/net/fs); new tool "delete_property_work" touches a sensitive surface (email/exec/net/fs); new tool "delete_document" touches a sensitive surface (email/exec/net/fs); new tool "list_categories" appeared; new tool "import_airbnb_csv" appeared; new tool "export_documents" touches a sensitive surface (email/exec/net/fs); new tool "get_projection" appeared; new tool "get_simulation" appeared; new hardcoded outbound host/BCC destination(s): openlmnp.fr, www.schemastore.org.

• Transport config

  fail10% of grade

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

  remote MCP endpoint declares NO authentication (unauthenticated remote — nginx-ui/CVE-2026-33032 class); source performs runtime self-update / download-and-execute (bypasses version_behavior)
