TickTick

Connections live under agent/connections/. Auth is brokered by Vercel Connect, so install the framework and the Connect SDK:

npm install eve@latest @vercel/connect

Create agent/connections/ticktick.ts. The connection name is derived from the filename:

// agent/connections/ticktick.tsimport { connect } from "@vercel/connect/eve";import { defineMcpClientConnection } from "eve/connections";export default defineMcpClientConnection({  url: "https://mcp.ticktick.com",  description: "TickTick: tasks, habits, and lists.",  auth: connect("ticktick"),});

Connect owns the OAuth flow, and each end-user authorizes in their own browser before their first tool call.

Create the connector, link it to your project, and pull OIDC locally:

vercel connect create ticktickvercel linkvercel env pull

See the Connections docs for principal types, headers, approval, and protocol-specific filters.
