Can I use n8n as a CLI?

Yes. KosmoKrator exposes a n8n CLI through kosmo integrations:call and the provider shortcut command. Commands can return JSON for scripts, CI, and coding agents.

Can I expose n8n through MCP?

Yes. The KosmoKrator MCP gateway can expose selected n8n tools to clients such as Claude Code, Cursor, Codex, and other MCP-compatible tools.

Where are n8n credentials stored?

n8n credentials are configured in KosmoKrator's local integration settings and reused by CLI, Lua, and MCP gateway surfaces.

Can I deny write access for n8n MCP tools?

Yes. Start the gateway with --write=deny for read-only clients, or use ask/allow only for trusted workspaces.

n8n CLI for Shell Scripts

Call integration functions from shell scripts with stable JSON input and output.

Use shell scripts for small local automations that need one or more integration calls. The n8n CLI uses the same integration registry as the TUI, Lua runtime, and MCP gateway, but returns predictable command output for automation.

Command Shape

# n8n CLI for Shell Scripts
kosmokrator integrations:configure n8n --set api_key="$N8N_API_KEY" --enable --read allow --write ask --json
kosmo integrations:call n8n.n8n_list_workflows '{"cursor":"example_cursor","limit":1}' --json

Discovery Before Execution

Agents and scripts can inspect n8n docs and schemas before choosing a function.

kosmo integrations:docs n8n --json
kosmo integrations:docs n8n.n8n_list_workflows --json
kosmo integrations:schema n8n.n8n_list_workflows --json
kosmo integrations:search "n8n" --json
kosmo integrations:list --json

`n8n.n8n_get_execution`	Read	execution_id	Get detailed information about a specific n8n workflow execution, including status, data, and node results.
`n8n.n8n_list_credentials`	Read	cursor, limit	List n8n credentials. Supports pagination with cursor and limit parameters.
`n8n.n8n_get_current_user`	Read	none	Get the authenticated n8n user's profile information, including name, email, and role.

Automation Notes

Use --json for machine-readable output.
Keep credentials out of argv by using environment variables or stored KosmoKrator configuration.
Configure read/write policy before unattended runs; use --force only for trusted automation.
Use the MCP gateway instead when the agent needs dynamic tool discovery inside a conversation.
