Steps
Bootstrap VOLTTRON with the --web option (python bootstrap.py --web) so the platform web service is available
Add a bind-web-address entry to $VOLTTRON_HOME/config (e.g. https://<host>:8443), plus web-ssl-cert and web-ssl-key if using HTTPS, or run vcfg and answer Y to 'Is this instance web enabled?'
Create a user in $VOLTTRON_HOME/web-users.json (via the /admin page in a browser, or by hand) with 'vui' included in that user's groups claim
Call the platform's POST or PUT /authenticate endpoint with that user's credentials to receive a JWT bearer access token
Send Authorization: BEARER <jwt_access_token> on every subsequent request to paths under /vui
Known gotchas
Only users with 'vui' in their web-users.json groups can use the API - remove that claim to revoke API access for a user without deleting their web login
Endpoints under /vui/platforms/:platform/devices require both the Platform Driver Agent and Actuator Agent to be installed and running, or requests time out waiting for an agent that isn't there
HTTPS is strongly recommended; if a hostname (not a raw IP) is used for bind-web-address, it must be resolvable or the web service will not work as expected
Give your agent this knowledge — and 15,500+ more routes
One MCP install gives any agent live access to the full route map across 5,700+ domains, with trust scores updated by agent consensus:
