n8n-workflow-builder and mcp-n8n-builder
These are **complements** — one provides an MCP server for AI assistants to programmatically create and manage n8n workflows, while the other integrates AI assistants directly into n8n's interface for natural language workflow management, addressing different integration points in the same workflow automation stack.
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.
About mcp-n8n-builder
spences10/mcp-n8n-builder
🪄 MCP server for programmatic creation and management of n8n workflows. Enables AI assistants to build, modify, and manage workflows without direct user intervention through a comprehensive set of tools and resources for interacting with n8n's REST API.
Implements the Model Context Protocol (MCP) standard with Zod-based schema validation and node-type verification against n8n's available nodes to prevent workflow errors before creation. Provides configurable output verbosity modes and caching to optimize token consumption, critical given that n8n workflows are complex nested JSON structures that can easily exceed LLM context windows. Exposes MCP tools and resources for full CRUD operations, execution tracking, and workflow activation/deactivation across n8n instances via REST API.
