n8n makes 70 MCP servers a one-click OAuth connection — and says when not to use them

On 10 August 2026 n8n added a batch of MCP servers connectable straight from the node panel through an OAuth flow, including Airtable, Grafana, Miro, New Relic, Jotform and PandaDoc, joining Notion, Stripe, GitLab, Apify, Linear, monday.com and Hugging Face for about 70 services. The post pairs the release with a selection rule: native nodes for deterministic steps where no judgement is needed, a node attached as an agent tool when the agent should choose the moment but not the action, and an MCP server when the agent should choose from a whole toolset — the last costing more agent reasoning. Servers outside the list still connect via the MCP Client Tool endpoint.

What it means The integration tax on agent workflows keeps falling, but the useful half here is the decision rule — most teams reach for an MCP server where a fixed tool would be cheaper and more predictable.
