n8n-MCP is an open-source Model Context Protocol server that gives AI assistants structured knowledge and tools for working with n8n. It is designed to help coding and agent clients understand n8n nodes, properties, operations, and workflow construction instead of relying on incomplete model memory about the automation platform.

The server exposes searchable information about n8n's node ecosystem and can support tasks such as discovering the right node, inspecting configuration fields, validating workflow structures, and generating or modifying automations. By presenting this information through MCP, it can be used from compatible AI clients without building a custom integration for each assistant.

n8n-MCP is particularly useful for developers who create n8n workflows with AI assistance. It reduces hallucination around node parameters and gives agents a more grounded view of the current n8n toolset, making generated workflows easier to validate and adapt.
