Cross-agent compatibility

Compatibility is AI-inferred and not yet hand-verified.

  • Claude Code Works
  • Codex Caveats No plugin install. Copy the SKILL.md folders into .agents/skills and configure the n8n-mcp MCP server manually.
  • OpenCode Caveats No plugin install. Drop the SKILL.md folders into .claude/skills or .agents/skills and configure the n8n-mcp MCP server.

What it does

A bundle of seven complementary skills that teach a coding agent how to build flawless n8n workflows through the n8n-mcp MCP server. Instead of letting the model guess at node configs and loop on validation errors, the skills encode the real rules: expression syntax, MCP tool selection, proven workflow patterns, node configuration, validation handling, and Code-node JavaScript and Python.

The seven skills:

  1. n8n Expression Syntax, correct {{ }} patterns and the webhook $json.body gotcha.
  2. n8n MCP Tools Expert, which n8n-mcp tool to use and the exact parameter formats.
  3. n8n Workflow Patterns, proven architectures (webhook, HTTP API, database, AI, scheduled).
  4. n8n Node Configuration, operation-aware config and property dependencies.
  5. n8n Validation Expert, reading and fixing validation errors without looping.
  6. n8n Code (JavaScript), writing Code-node JS with the right $input / $json access.
  7. n8n Code (Python), the same for Python, with standard-library limits called out.

Our take

If you build n8n workflows with an agent, this is the difference between a workflow that runs and one that loops on validation errors for twenty minutes. The MCP Tools Expert skill alone earns its place by stopping the agent from misusing n8n-mcp. It is the most popular skill in its niche for good reason. Top pick for any team automating with n8n.

When to use it

  • You build or maintain n8n workflows and use an agent to do it.
  • You have the n8n-mcp MCP server available (these skills assume it).
  • You keep hitting validation errors or node-config mistakes the agent cannot self-correct.

When not to

  • You do not use n8n. Nothing here transfers to other automation tools.
  • You cannot run the n8n-mcp MCP server in your environment.

Cross-agent note

Distributed as a Claude Code plugin, so the one-line install is Claude Code only. The underlying skills are plain SKILL.md folders and port to Codex and OpenCode by copying them into the agent's skills directory and configuring the n8n-mcp MCP server. We have not yet hand-verified those ports, so the compatibility flags are AI-inferred.
