Why n8n-mcp is the candidate
n8n-mcp passed every step in Cursor. It is the group’s site-wide candidate (judged 2026-10-21): Searched n8n's node library for 'slack' and returned the Slack node in both Claude Code and Cursor (2 calls in total), with nothing but the published snippet: no n8n instance, account or key. It also passed in ChatGPT (Codex) on Oct 15. Runner-up Langflow ran our fixture flow and returned the fresh code in both clients in 2 calls in total, but it needs a running Langflow server and an API key. n8n's own instance-level MCP passed both tasks (node search and running a fixture workflow) in both clients too, but needs a running n8n instance with an access token and took 8 calls on the workflow task (4 per client) against Langflow's 2. Confirmed Oct 21, 2026: a second run in Claude Code and Cursor passed again (n8n-mcp 2.94.3).
Provisional: based on one dated run per app (no repeat runs yet), so treat it as a candidate, not a final pick. How we test.
