📄 Description

Optionally customizing the resource in protected resource metadata endpoints

It defaults to the baseURL.

export const auth = betterAuth({
    plugins: [
        mcp({
            loginPage: "/sign-in",
            resource: "http://localhost:3000/mcp"
        })
    ]
});

Summary by cubic

Adds support to customize the resource returned by the MCP protected resource metadata endpoint. By default, it now uses the base URL origin instead of the full base URL.

  • New Features

    • New MCP plugin option: resource to override the protected resource metadata resource.
    • getMCPProtectedResourceMetadata now accepts MCPOptions; resource defaults to new URL(baseURL).origin.
    • jwks_uri and scopes_supported now read from oidcConfig.metadata.
    • Docs updated to include the resource option.

  • Migration

    • If you relied on resource being the full baseURL (including path), set resource to baseURL to keep old behavior.
    • If you call getMCPProtectedResourceMetadata directly, update usage to pass MCPOptions.
