Expose n8n Workflows as MCP Server for AI Integration

Unlock Seamless AI Integration with the Expose n8n Workflows as MCP Server

Transform your automation capabilities with our groundbreaking solution that exposes your n8n workflows as an MCP Server, effortlessly integrating AI functionalities. Allow MCP clients, such as Claude Desktop, to seamlessly discover, manage, and execute tagged workflows, paving the way for advanced automation.

What this workflow does

This innovative solution provides a robust MCP server endpoint that supports five essential tools:

• search_workflows: Utilize the n8n API to search for workflows with specified tags, returning valuable details such as workflow ID, name, sticky-note description, and input schema from Sub-workflow triggers.
• add_workflow: Validate and add the requested workflow IDs to the 'mcp_available_workflows' Data Table, allowing specific workflows to run.
• remove_workflow: Remove unwanted workflows from the execution pool to maintain efficient workflow management.
• list_workflows: Retrieve and display profiles and input schemas of all allowlisted workflows from the Data Table.
• execute_workflow: Execute selected n8n workflows that are part of the allowlist, leveraging provided parameters, and returning the execution outcome.

Additionally, this workflow can handle chat messages in n8n, utilizing an OpenAI-backed agent with MCP client connections to thoroughly test the MCP tools interactions.

Use cases

Revamp your automation landscape using this workflow in scenarios such as:

• Enabling AI-powered automation where MCP clients access specific workflows for complex data processing tasks.
• Streamlining operations in SaaS applications by integrating selected, well-defined workflow routines.
• Facilitating seamless collaboration among automation engineers through efficient workflow management and execution.

Technical details

This workflow leverages a strong technical foundation using these n8n nodes and features:

• if: Conditional operations for optimized workflow execution paths.
