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 215 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

  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

  warn10% of grade

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

  vs prior 0.1.0 (minor bump): new tool "contracts.dual_plane" appeared; new tool "contracts.errors" appeared; new tool "workspaces.capabilities" appeared; new tool "workspaces.directory.list" appeared; new tool "workspaces.listing.read" touches a sensitive surface (email/exec/net/fs); new tool "platform.launch.readiness" appeared; new tool "workspaces.invites.create" appeared; new tool "workspaces.join" appeared; new tool "workspaces.billing.accounts.create" appeared; new tool "workspaces.billing.accounts.list" appeared; new tool "workspaces.billing.instruments.attach" appeared; new tool "workspaces.billing.instruments.list" appeared; new tool "workspaces.billing.instruments.verify" appeared; new tool "workspaces.billing.delegated_spend_grants.create" appeared; new tool "workspaces.billing.delegated_spend_grants.list" appeared; new tool "workspaces.billing.delegated_spend_grants.revoke" appeared; new tool "workspaces.billing.envelopes.create" appeared; new tool "workspaces.billing.envelopes.list" appeared; new tool "workspaces.billing.envelopes.revoke" appeared; new tool "workspaces.billing.envelopes.status" appeared; new tool "workspaces.billing.usage_summary" appeared; new tool "workspaces.billing.settlements" appeared; new tool "workspaces.providers.catalog" appeared; new tool "workspaces.providers.quotes.create" appeared; new tool "workspaces.providers.quotes.execute" appeared; new tool "workspaces.providers.executions.list" appeared; new tool "workspaces.launch.profile" appeared; new tool "workspaces.launch.curation" appeared; new tool "workspaces.launch.regions" appeared; new tool "workspaces.launch.capability_status" appeared; new tool "workspaces.objective.status" appeared; new tool "workspaces.task.status" appeared; new tool "workspaces.leases.request" appeared; new tool "workspaces.leases.approve" appeared; new tool "workspaces.leases.revoke" appeared; new tool "workspaces.objectives.create" appeared; new tool "workspaces.tasks.create" appeared; new tool "workspaces.tasks.claim" appeared; new tool "workspaces.tasks.complete" appeared; new tool "workspaces.feed.read" touches a sensitive surface (email/exec/net/fs); new tool "workspaces.receipts.bridge.list" appeared; new tool "workspaces.receipts.bridge.get" appeared; new tool "workspaces.bridge.health" appeared.

• 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)
