🪄 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.

How to read this: tool names here are observed from a live tools/list handshake. The Risk label is a heuristic inferred from the tool name (write/destructive verbs), not from executing the tool — a conservative guess, not a verified capability. We never escalate risk from a description. Found one that's wrong? Tell us — we fix on report.
| Tool | Risk | Side effects | Approval |
|---|---|---|---|
| create_workflow Creates a new workflow in n8n with specified nodes and connections. Note that only workflows with automatic trigger nodes (schedule, webhook, etc.) can be activated - workflows with only manual triggers cannot be activated. Returns the created workflow with its assigned ID. | write | true | unknown |
| activate_workflow Activates a workflow by its ID, enabling it to run automatically based on its trigger (schedule, webhook, etc.). Note that only workflows with automatic trigger nodes can be activated - workflows with only manual triggers cannot be activated. | unknown | unknown | unknown |
| delete_workflow Permanently deletes a workflow by its ID. This action cannot be undone, so use with caution. Consider deactivating workflows instead if you might need them again later. | destructive | true | true |
| list_workflows Lists all workflows from n8n with their basic information including ID, name, status, creation date, and tags. Use this tool to get an overview of available workflows before performing operations on specific workflows. Results can be filtered by active status, tags, or name. | read | false | unknown |
| deactivate_workflow Deactivates a workflow by its ID, preventing it from running automatically. The workflow will still exist and can be manually executed or reactivated later. Use this instead of deleting workflows that you might need again. | destructive | true | true |
| list_available_nodes Lists all available nodes in the n8n instance. Use this tool BEFORE creating or updating workflows to ensure you only use valid node types. This helps prevent errors caused by using node types that do not exist in the current n8n instance. | read | false | unknown |
| get_workflow Retrieves complete details of a specific workflow by its ID, including all nodes, connections, settings, and metadata. Use this tool when you need to examine a workflow's structure before updating it or to understand how it works. | read | false | unknown |
| get_execution Retrieves detailed information about a specific workflow execution, including execution time, status, and optionally the full data processed at each step. Particularly useful for debugging failed workflows or understanding data transformations between nodes. | read | false | unknown |
| list_executions Lists workflow execution history with details on success/failure status, duration, and timestamps. Use this tool to monitor workflow performance, troubleshoot issues, or verify that workflows are running as expected. Results can be filtered by workflow ID, status, and limited to a specific number. | read | false | unknown |
| update_workflow Updates an existing workflow with new configuration. Typically used after retrieving a workflow with get_workflow, modifying its structure, and then saving the changes. The entire workflow structure must be provided, not just the parts being changed. | write | true | unknown |

This is one server. A loadout combines the right servers, governance, and proven plays for a whole job — assembled deliberately, not tool-dumped.
