Nodes environment variables
Environment variable to configure nodes management in self-hosted n8n instance.
Nodes environment variables
File-based configuration
You can add _FILE to individual variables to provide their configuration in a separate file. Refer to Keeping sensitive data in separate files for more details.
This page lists the environment variables configuration options for managing nodes in n8n, including specifying which nodes to load or exclude, importing built-in or external modules in the Code node, and enabling community nodes.
| Variable | Type | Default | Description |
|---|---|---|---|
N8N_COMMUNITY_PACKAGES_ENABLED | Boolean | true | Enables (true) or disables (false) the functionality to install and load community nodes. If set to false, neither verified nor unverified community packages will be available, regardless of their individual settings. |
N8N_COMMUNITY_PACKAGES_PREVENT_LOADING | Boolean | false | Prevents (true) or allows (false) loading installed community nodes on instance startup. Use this if a faulty node prevents the instance from starting. |
N8N_COMMUNITY_PACKAGES_REGISTRY | String | https://registry.npmjs.org | NPM registry URL to pull community packages from (license required). |
N8N_CUSTOM_EXTENSIONS | String | - | Specify the path to directories containing your custom nodes. |
N8N_PYTHON_ENABLED | Boolean | true | Whether to enable Python execution on the Code node. |
N8N_UNVERIFIED_PACKAGES_ENABLED | Boolean | true | When N8N_COMMUNITY_PACKAGES_ENABLED is true, this variable controls whether to enable the installation and use of unverified community nodes from an NPM registry (true) or not (false). |
N8N_VERIFIED_PACKAGES_ENABLED | Boolean | true | When N8N_COMMUNITY_PACKAGES_ENABLED is true, this variable controls whether to show verified community nodes in the nodes panel for installation and use (true) or to hide them (false). |
NODE_FUNCTION_ALLOW_BUILTIN | String | - | Permit users to import specific built-in modules in the Code node. Use * to allow all. n8n disables importing modules by default. |
NODE_FUNCTION_ALLOW_EXTERNAL | String | - | Permit users to import specific external modules (from n8n/node_modules) in the Code node. n8n disables importing modules by default. |
NODES_ERROR_TRIGGER_TYPE | String | n8n-nodes-base.errorTrigger | Specify which node type to use as Error Trigger. |
NODES_EXCLUDE | Array of strings | [\"n8n-nodes-base.executeCommand\", \"n8n-nodes-base.localFileTrigger\"] | Specify which nodes not to load. For example, to block nodes that can be a security risk if users aren't trustworthy: NODES_EXCLUDE: "[\"n8n-nodes-base.executeCommand\", \"@n8n/n8n-nodes-langchain.lmChatDeepSeek\"]". To enable all nodes, specify NODES_EXCLUDE: "[]". |
NODES_INCLUDE | Array of strings | - | Specify which nodes to load. |
