Linear

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/linear.ts. The connection name is derived from the filename:

// agent/connections/linear.tsimport { connect } from "@vercel/connect/eve";import { defineMcpClientConnection } from "eve/connections";export default defineMcpClientConnection({  url: "https://mcp.linear.app/mcp",  description: "Linear workspace: issues, projects, cycles, and comments.",  auth: connect("linear"),});

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 linearvercel linkvercel env pull

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