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 193 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

  fail15% of grade

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

  tool "federation_catalog_search_multi" has a secret-shaped input parameter "auth_token" — secrets must never be tool parameters (the model would supply/handle the credential). tool "federation_catalog_search_grouped_multi" has a secret-shaped input parameter "auth_token" — secrets must never be tool parameters (the model would supply/handle the credential).

• Permission scope

  unscannable15% of grade

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

  No source files, package.json, or pyproject were fetched; cannot infer capability scope.

• 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 2.0.0 (patch bump): tool "federation_list_tenants" description changed (wording only, no injection pattern); tool "federation_tenant_info" description changed (wording only, no injection pattern); tool "federation_journal_read" description changed (wording only, no injection pattern); tool "moltbook_read" description changed (wording only, no injection pattern); tool "federation_attest" description changed (wording only, no injection pattern); tool "federation_key_status" description changed (wording only, no injection pattern); tool "federation_help" description changed (wording only, no injection pattern); tool "federation_why" description changed (wording only, no injection pattern); tool "federation_governance" description changed (wording only, no injection pattern); tool "legal_get" description changed (wording only, no injection pattern); tool "federation_pricesheet" description changed (wording only, no injection pattern); tool "federation_catalog_search_multi" description changed (wording only, no injection pattern); tool "federation_catalog_search_grouped_multi" description changed (wording only, no injection pattern); tool "federation_catalog_version" description changed (wording only, no injection pattern); tool "federation_catalog_platforms" description changed (wording only, no injection pattern); tool "federation_catalog_agents" description changed (wording only, no injection pattern); tool "federation_arena" description changed (wording only, no injection pattern); tool "federation_latency" description changed (wording only, no injection pattern); tool "federation_solvency" description changed (wording only, no injection pattern); tool "federation_choice_compare" description changed (wording only, no injection pattern); tool "federation_choice_get" description changed (wording only, no injection pattern); tool "federation_search" description changed (wording only, no injection pattern); tool "federation_enter_tenant" description changed (wording only, no injection pattern); tool "about_us_about" description changed (wording only, no injection pattern); tool "how_to_about" description changed (wording only, no injection pattern); tool "introspection_system_confidence" description changed (wording only, no injection pattern); tool "introspection_system_coverage_gaps" description changed (wording only, no injection pattern); tool "introspection_system_probe" description changed (wording only, no injection pattern); tool "introspection_system_diff" description changed (wording only, no injection pattern); tool "introspection_corpus_query" description changed (wording only, no injection pattern); tool "introspection_corpus_probe_scope" description changed (wording only, no injection pattern); tool "introspection_corpus_probe_disagreement" description changed (wording only, no injection pattern); tool "introspection_corpus_compare" description changed (wording only, no injection pattern); tool "introspection_system_climb_history" description changed (wording only, no injection pattern); tool "introspection_system_list_nodes" description changed (wording only, no injection pattern); tool "introspection_system_list_repos" description changed (wording only, no injection pattern); tool "introspection_system_change_graph" description changed (wording only, no injection pattern); tool "introspection_system_change_reach" description changed (wording only, no injection pattern); tool "introspection_system_co_decisions" description changed (wording only, no injection pattern); new tool "federation_offer" touches a sensitive surface (email/exec/net/fs).

• Transport config

  pass10% of grade

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

  remote endpoint "https://mcp.comos-gateway.com/mcp/sse" uses TLS (https); remote endpoint uses OAuth (strongest auth mode)
