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.

20/24 tools missing one or more hints — n8n_create_workflow (missing: idempotentHint); n8n_get_workflow (missing: destructiveHint); n8n_delete_workflow (missing: idempotentHint), +17 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
1 critical, 1 high severity in production deps — form-data@4.0.0 (critical), form-data@4.0.0 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.

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.
