Plain
for LuumenAI
Read Plain threads and customers, then reply or update records with approval.
Connect Plain and your agent can read support threads, customers, companies, tiers, and linked issue tracker records without leaving the terminal. It can trace a thread back to the customer and their tier before you decide anything. Changes — sending a message, updating a thread, upserting a customer — are previewed and held for your approval by default. Luumen authenticates with an API key.

Questions
Authorize once with API token. Luumen lists the scopes each action needs before you approve the connection, and credentials never appear in the chat.
Read actions answer immediately. Anything that writes — add customer to group, create customer group, create thread, delete customer, and more — is shown as a plan and requires approval by default, including the 3 actions classified as destructive. Administrators configure that per tool, so you decide exactly which actions can ever run unattended.
You decide. Actions are granted per agent, skill, and team, and per environment — production is not staging. Read access can be broad while writes stay narrow.
Every call to Plain — read or write, approved or declined — is recorded with the actor, the input, and the result, and can be linked to the ticket or change record.
