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 "clipform_search_media" description: cross-tool redirection ('instead of call…'). tool "clipform_check_render" param "job_ids" description: cross-tool redirection ('instead of call…').

• 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 2.6.0 (minor bump): tool "clipform_create_form" description changed (wording only, no injection pattern); tool "clipform_create_form" gained secret/exfil-shaped input(s): context; tool "clipform_import_form" gained secret/exfil-shaped input(s): context; tool "clipform_list_forms" gained secret/exfil-shaped input(s): context; tool "clipform_whoami" gained secret/exfil-shaped input(s): context; tool "clipform_get_form" gained secret/exfil-shaped input(s): context; tool "clipform_update_form" gained secret/exfil-shaped input(s): context; tool "clipform_delete_form" gained secret/exfil-shaped input(s): context; tool "clipform_get_results" gained secret/exfil-shaped input(s): context; tool "clipform_get_responses" gained secret/exfil-shaped input(s): context; tool "clipform_add_node" gained secret/exfil-shaped input(s): context; tool "clipform_update_node" gained secret/exfil-shaped input(s): context; tool "clipform_delete_node" gained secret/exfil-shaped input(s): context; tool "clipform_upload_media_asset" gained secret/exfil-shaped input(s): context; tool "clipform_complete_media_upload" gained secret/exfil-shaped input(s): context; tool "clipform_attach_node_media" gained secret/exfil-shaped input(s): context; tool "clipform_get_node_media" gained secret/exfil-shaped input(s): context; tool "clipform_delete_node_media" gained secret/exfil-shaped input(s): context; tool "clipform_set_logic" gained secret/exfil-shaped input(s): context; tool "clipform_log_generation" gained secret/exfil-shaped input(s): context; tool "clipform_search_news" gained secret/exfil-shaped input(s): context; tool "clipform_generate_tts" gained secret/exfil-shaped input(s): context; tool "clipform_generate_video" gained secret/exfil-shaped input(s): context; tool "clipform_search_media" gained secret/exfil-shaped input(s): context; tool "clipform_render_composition" gained secret/exfil-shaped input(s): context; tool "clipform_search_music" gained secret/exfil-shaped input(s): context; tool "clipform_list_compositions" gained secret/exfil-shaped input(s): context; tool "clipform_list_video_templates" gained secret/exfil-shaped input(s): context; tool "clipform_render_video_template" gained secret/exfil-shaped input(s): context; tool "clipform_list_assets" gained secret/exfil-shaped input(s): context; tool "clipform_check_render" gained secret/exfil-shaped input(s): context; tool "clipform_fetch_boundary" gained secret/exfil-shaped input(s): context; tool "clipform_get_guide" description changed (wording only, no injection pattern); tool "clipform_get_guide" gained secret/exfil-shaped input(s): context; tool "clipform_get_workflow" description changed (wording only, no injection pattern); tool "clipform_get_workflow" gained secret/exfil-shaped input(s): context; new tool "get_more_tools" appeared.

• Transport config

  warn10% of grade

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

  sends telemetry to third-party SDK (posthog) — disclosure, verify opt-in; manifest/source references telemetry behavior — disclosure
