Trello Connector

Read-safe Trello connector using the provider's supported composite Authorization header.

Credential setup

api_key_header

Enter `OAuth oauth_consumer_key="<key>", oauth_token="<token>"`; Trello treats the token as password-equivalent.

Setup docs: https://trello.com/power-ups/admin

After adding this connector, attach the credential on the server page, then run astrail tools list.

Hosted MCP endpoint

/api/mcp/preset-trello

Private servers require an Astrail API key in the Authorization header.
