# Tool selection at install time:
|
|
# n8n's bridge exposes 11 tools. Mutating ones (activate/deactivate, docker
|
|
# container_logs) are pruned from the default so a user who installs casually
|
|
# gets a read-mostly safe surface. Users see the full list in the install-time
|
|
# checklist and can opt into the mutating tools per their threat model.

The n8n bridge expects to talk to a running n8n instance over the URL you
|
|
provided. Generate an API key in n8n under Settings → API.
|
|
|
|
Workflow activate/deactivate calls are real mutations against your live n8n.
|
|
Treat them carefully.
|
|
|
|
Start a new Hermes session to load the n8n tools.
