Workflow
Agent: "Slack에 메시지 보내는 워크플로우 만들어"
1. search_templates("slack message") → 비슷한 템플릿 발견
2. get_template(1105) → 전체 노드 구성/파라미터 확인
3. get_doc("n8n-nodes-base.slack") → Slack 노드 사용법 참조
4. 두 정보 결합 → 새 워크플로우 JSON 생성
Setup
The doc cache lives at ~/.cache/docs-n8n-mcp/ and auto-populates on first run (~1,500 files, ~5s via tarball). Cache refreshes automatically after 7 days. Template tools call the n8n.io API live (no cache needed).
cd /home/okdk/docs-n8n-mcp
uv run python fetcher.py # manual cache population
OpenCode MCP registration
Registered in ~/.config/opencode/opencode.json as docs-n8n.
