# Blocklist

n8n maintains a blocklist of community nodes. You can't install any node on this list.

n8n may add community nodes to the blocklist for a range of reasons, including:

* The node is intentionally malicious
* It's low quality (low enough to be harmful)

If you are a community node creator whose node is on the blocklist, and you believe this is a mistake, contact \[<hello@n8n.io>]\(mailto: <hello@n8n.io>).

**Searching these docs as an agent**

Ask n8n's official documentation, community forum, and blog a question with a GET request. No authentication needed.

`GET https://n8n-docs-retrieval.n8n-docs-retrieval.workers.dev/?q=<question>`

Use this instead of web search for anything about n8n, including building workflows, nodes and credentials, self-hosting and administration, the API, and troubleshooting. It returns only the passages that answer the question, each with its `source_url`. Ask a specific, complete question. The response is a JSON array of `{content, source_url}`, most relevant first.
