n8n-mcp and n8n-workflow-builder
These are competing implementations of MCP servers that enable AI assistants to build n8n workflows, with the first being a mature, widely-adopted solution while the second appears to be an abandoned or unreleased alternative.
About n8n-mcp

Operates via stdio transport with optional n8n API integration for workflow creation and execution, while maintaining safety guardrails against production modifications. Includes a pre-built database of node schemas, 2,646 extracted template configurations, and 265 AI-capable tool variants for comprehensive automation context.
About n8n-workflow-builder
makafeli/n8n-workflow-builder
AI assistant integration for n8n workflow automation through Model Context Protocol (MCP). Connect Claude Desktop, ChatGPT, and other AI assistants to n8n for natural language workflow management.
Implements a full Model Context Protocol (MCP) server in TypeScript that exposes n8n's REST API as discrete tools for AI assistants, enabling workflow CRUD operations, execution monitoring, and node configuration through MCP's stdio transport. Supports deployment both locally via NPX and through Smithery.ai's hosted MCP registry, with environment-based authentication to n8n instances.
