PlanetScale

Add the connection from eve's registry. This writes the initial definition under agent/connections/ and installs its authentication dependency when needed:

eve add connection/planetscale

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

// agent/connections/planetscale.tsimport { connect } from "@vercel/connect/eve";import { defineMcpClientConnection } from "eve/connections";
export default defineMcpClientConnection({  url: "https://mcp.pscale.dev/mcp/planetscale",  description: "PlanetScale: query Postgres and MySQL databases.",  auth: connect("planetscale"),});

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

Link your project, create the connector, and pull OIDC locally:

vercel linkvercel connect create planetscalevercel env pull

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