Scalekit

Scalekit integration is available via rust-mcp-extra.

[dependencies]
rust-mcp-extra = "1.0"

use rust_mcp_extra::auth_provider::scalekit::{ScalekitAuthProvider, ScalekitAuthOptions};

let auth_provider = ScalekitAuthProvider::new(ScalekitAuthOptions {
    // Scalekit environment URL (from the dashboard, Settings section).
    // A missing https:// prefix is added automatically.
    environment_url: "https://your-env.scalekit.com".to_string(),
    // MCP server resource ID (from the dashboard, MCP Servers section)
    resource_id: "sk_resource_...".to_string(),

    resource_documentation: None,
    token_verifier: None,

let server = create_axum_server(
    server_info,
    handler,
    AxumServerOptions {
        auth: Some(Arc::new(auth_provider)),
        ..Default::default()
    },
);

ScalekitAuthProvider::new is async - it pulls the authorization-server metadata from {environment_url}/.well-known/oauth-authorization-server/resources/{resource_id} during construction. Tokens are verified with cached JWKS signature checks; the verifier is replaceable via token_verifier.

See rust_mcp_extra::auth_provider::scalekit for the full ScalekitAuthOptions reference.
