n8n — can an agent use it?
n8n is built for agents from the ground up: a built-in official MCP server that lets AI assistants create, edit, and run workflows, plus a self-hostable architecture that gives teams full control. The main gap is the lack of agent payment protocols — but since n8n can be self-hosted for free, the payment friction is low.

FIND & RETRIEVE7.7/10Can an agent get correct information?
Machine-readable surface7/10
Well-formed llms.txt with reports available in markdown. Sitemap index with 12 sub-sitemaps referenced in robots.txt. Server-rendered HTML (1,269 words without JS). JSON-LD present but only Organization type — no Product/Offer markup on pricing. Homepage explicitly says 'See llms.txt for all machine-readable content.' Missing: no .well-known/mcp.json despite having MCP, no H1 tag on homepage. source
Information retrieval quality7.5/10
Pricing published clearly: Starter 20 EUR/mo, Pro 50 EUR/mo, Business 667 EUR/mo, Enterprise contact sales. Execution-based pricing with unlimited steps — transparent and predictable. Feature comparison table is comprehensive across all tiers. Free trial available (no credit card). Self-hosted community edition is free. No API rate limits documented publicly. source
Documentation for machines8.5/10
Comprehensive docs at docs.n8n.io: getting started, build workflows, deploy guides, MCP server docs, API reference, changelog. Every page available as markdown (append .md to URL). Full documentation export at llms-full.txt. Docs header states 'For the complete documentation index, see llms.txt.' Built-in query interface for AI agents (?ask= parameter). Developer community forum and dedicated support. source
ACT & TRANSACT6.9/10Can an agent do the job?
Action coverage8/10
REST API covers workflows (CRUD, publish/unpublish), executions (query, delete, status filter), credentials (create, delete, get schema), and security audits. MCP server allows creating workflows from natural language descriptions, editing existing ones (n8n 2.13+), running workflows, and managing data tables. Self-hosted means the entire platform is controllable. SSL limitation on the n8n node requires HTTP Request node for secure connections. source
Agent protocol support9/10
Built-in official MCP server — not third-party. Supports HTTP transport with OAuth or API key authentication. One-line connection commands documented for Claude Desktop, Claude Code, and OpenAI Codex CLI on the docs homepage. Tools cover the service's core actions: create/edit/run workflows, manage data tables, search workflows. Also has MCP Client node (connect to external MCP servers) and MCP Server Trigger node, making n8n both an MCP client and server. source
Access & auth friction8/10
Self-serve credentials: cloud free trial with no credit card required, instant API key access. MCP server supports OAuth or API key authentication. Self-hosted means full auth control — no vendor approval needed. No enterprise gate on API access. SSO SAML and LDAP on Business+ plans. source
Agent payment capability2/10
No agent payment protocols (ACP, AP2, MPP, x402). Cloud plans require human subscription through the n8n website. No programmatic checkout. Self-hosted community edition is free (fair-code license), which reduces but does not eliminate the gap — paid tiers still require human sign-up. source
Cost & rate fairness7.5/10
Self-hosted community edition is free and open source (fair-code license, 203k GitHub stars). Cloud tiers start at 20 EUR/mo with execution-based pricing (unlimited steps per execution, unlike competitors). Unlimited users on all plans. No agent-vs-human price discrimination. Self-hosted means you control your own rate limits. No explicit API rate limits documented for cloud, but auto-upgrade possible if usage exceeds plan limits (14-day notice). source
TRUST & DURABILITY8.0/10Will it still work next quarter?
Permission & ToS stance8.5/10
Automation is the entire product — n8n's business IS enabling agent workflows. robots.txt is minimal and permissive (only blocks /cdn-cgi/). No AI-specific bot blocks. GPTBot and ClaudeBot both get HTTP 200. AI Terms explicitly state 'n8n will not use Customer Content or Output to train machine learning models.' Self-serve terms restrict to 'internal business purposes' (no resale), which is standard SaaS, not anti-agent. No hostile enforcement history. source
Reliability & continuity7.5/10
Public status page at status.n8n.cloud with uptime tracking. Self-hosted option means teams control their own uptime. 203k GitHub stars with active development and regular releases. Changelog maintained. SOC reports and Trust Center available. Fair-code license provides full source access. n8n GmbH (Berlin) as a stable commercial entity behind the open-source project. source

Point-in-time assessment — services change terms, prices and APIs often. That volatility is itself scored under Reliability & continuity. Re-verified at least quarterly.
