M8ven verifies MCPs across every public registry — install directly from whichever one you prefer.
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.

No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
42/42 tools missing one or more hints — n8n_create_workflow (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); n8n_get_workflow (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); n8n_get_workflow_details (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +39 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Secrets stay with their owner
2 secret/sensitive values flow into network calls (MCP_AUTH_TOKEN → dynamic, AUTH_TOKEN → dynamic)
Audit where credentials are sent. A NOTION_TOKEN should only reach api.notion.com — never a third-party host.
Secrets not logged
3 secret values sent to console.log
Redact or omit secret values from log output.
Production dependencies are patched
4 critical, 12 high severity in production deps — n8n@1.119.1 (critical), n8n@1.119.1 (critical)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Dev dependencies
12 critical/high in dev-only deps (does not ship to users)
Upgrade dev dependencies when convenient.

Add it once and ask Claude, ChatGPT, or any MCP client to grade a server, surface CVEs, check the publisher, and suggest safer alternatives — before you install.
