n8n Workflow Automation

List all workflows in your n8n instance. Returns workflow IDs, names, active status, and tags. Use this to discover available workflows before triggering them.

Get detailed information about a specific workflow including all nodes, connections, and settings. Use this to understand what a workflow does before executing it.

List workflow executions with optional filters. Returns execution status, start/end times, and workflow info. Use this to monitor workflow runs.

Get detailed information about a specific execution including all node outputs, errors, and timing. Use this to debug failed executions or retrieve workflow results.

List all tags in your n8n instance. Tags help organize workflows into categories.

Get the webhook URL for a workflow that has a Webhook trigger node. Use this to know where to send HTTP requests to trigger the workflow.

Get detailed workflow information including node counts, connection counts, tags, and node summary. More structured than get_workflow for quick analysis.

Get a simplified view of workflow structure showing only nodes and connections. Useful for understanding workflow topology without full configuration details.

Get minimal workflow info: ID, name, active status, tags, and timestamps. Fastest way to check workflow state without loading full definition.

Validate a workflow's structure by checking for common issues: missing connections, disconnected nodes, missing credentials, and invalid configurations.

Workflow version management via execution records. List history, rollback (deactivate for safety), or prune old executions.

Check n8n API connectivity and get instance information. Returns API status, version, and basic instance health.

Get comprehensive diagnostic information about the n8n instance including version, active workflow count, recent execution stats, and API connectivity.

List all credentials configured in your n8n instance. Returns credential names, types, and IDs. Secrets are always redacted by n8n. Use to audit which credentials are available for use in workflows.

Create a new workflow. Provide the workflow definition including nodes and connections. The workflow is created in inactive state by default. Common node types: n8n-nodes-base.webhook, n8n-nodes-base.httpRequest, n8n-nodes-base.code, n8n-nodes-base.if, n8n-nodes-base.switch, n8n-nodes-base.merge, n8n-nodes-base.set, n8n-nodes-base.scheduleTrigger, n8n-nodes-base.emailSend, n8n-nodes-base.function, n8n-nodes-base.noOp, n8n-nodes-base.wait, n8n-nodes-base.splitInBatches.

Update an existing workflow. Can modify nodes, connections, settings, or rename the workflow.

Activate a workflow so it can be triggered by webhooks, schedules, or other trigger nodes. Only active workflows respond to triggers.

Deactivate a workflow to stop it from responding to triggers. The workflow can still be executed manually.

Execute a workflow immediately with optional input data. Returns the execution ID to track progress. Use this to trigger workflows on-demand from AI agents.

Stop a running execution. Use this to cancel long-running or stuck workflows.

Create a new tag for organizing workflows.

Trigger a workflow via its webhook URL with custom data. This is an alternative to execute_workflow for workflows with Webhook trigger nodes.

Incrementally update specific parts of a workflow without replacing the entire definition. Can update name, settings, add/remove/update individual nodes, and modify tags.

Auto-fix common workflow issues such as disconnected nodes, missing default parameters, and invalid settings. Returns a summary of fixes applied.

Clone an existing workflow with a new name. Creates an inactive copy with all nodes, connections, and settings preserved. Useful for creating variations or backup copies before making changes.

Delete a workflow permanently. This cannot be undone. All execution history for this workflow will also be deleted.

Delete an execution record. This removes the execution from history but doesn't affect the workflow itself.
