Closes #2

Do not merge yet

This is the ready follow-up for when Scalekit ships as a first-class mcp-use provider. main must stay on the local verifier until mcp-use/oauth/scalekit installs from npm. Merging now would break clone-and-run.

Merge gates

  • feat(oauth): add Scalekit provider mcp-use/mcp-use#2272 is merged
  • A published mcp-use release exports mcp-use/oauth/scalekit
  • This PR bumps mcp-use from 2.1.0 to that release
  • npm install + npm run typecheck succeed
  • Inspector + whoami still work with environment URL, resource id, and public MCP URL only

Context

This example prototyped Scalekit OAuth with a local JWT/JWKS file so people can clone and run today. The first-class factory belongs in mcp-use, not here.

Prior work Link
This repo: local verifier + how-to #1 (merged)
mcp-use: announce the provider mcp-use/mcp-use#2271
mcp-use: add oauthScalekitProvider mcp-use/mcp-use#2272 (open)
This follow-up #2

The Scalekit cookbook on docs.scalekit.com is a separate change in developer-docs. It is not this PR and not the mcp-use provider page.

What this PR changes

  • index.ts imports oauthScalekitProvider from mcp-use/oauth/scalekit
  • Deletes oauth/scalekit.ts
  • Drops the direct jose dependency (only used by the local verifier)
  • README / in-repo how-to tell the reader to set environment URL, resource id, and public MCP URL only

The factory call is unchanged:

import { oauthScalekitProvider } from "mcp-use/oauth/scalekit";

oauth: oauthScalekitProvider({
  environmentUrl: process.env.SCALEKIT_ENVIRONMENT_URL!,
  resourceId: process.env.SCALEKIT_RESOURCE_ID!,
  resource: process.env.MCP_URL!,
}),

After npm publishes

  1. Bump mcp-use in package.json to the release that includes Scalekit
  2. Run npm install and npm run typecheck
  3. Confirm Inspector login + whoami
  4. Mark this PR ready and merge

Until then, leave this draft. Do not copy live usr_… / ses_… / m2m_… ids into comments.

Summary by CodeRabbit

  • Documentation

    • Updated Scalekit authentication guidance to use the published provider package.
    • Clarified JWT verification and distinguished the repository runbook from the linked how-to.
    • Removed outdated draft and prototype references.
  • Refactor

    • Switched Scalekit OAuth integration to the package-provided implementation.
    • Removed the local Scalekit OAuth adapter and its direct JWT verification support.

Import oauthScalekitProvider from mcp-use/oauth/scalekit and delete the local JWT verifier. Do not merge until an mcp-use release actually exports that path.

📝 Walkthrough

Walkthrough

The example now uses the published mcp-use/oauth/scalekit provider. It removes the local OAuth implementation and jose dependency. The README and Scalekit documentation now describe the published provider and current how-to.

Changes

Scalekit provider migration

Layer / File(s) Summary
Adopt the published provider
index.ts, oauth/scalekit.ts, package.json
index.ts imports oauthScalekitProvider from mcp-use/oauth/scalekit. The local provider and direct jose dependency are removed.
Align project documentation
README.md, docs/v2/typescript/server/authentication/providers/scalekit.mdx
The README references the published provider and the external how-to. The Scalekit page removes its draft note and unused Aside import.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔴 Critical · up to 74f23

This change switches the example to an OAuth provider that is not available from the currently pinned mcp-use release, so installs and type checking will fail and clone-and-run will be broken. Merge should remain blocked until the provider is published, the dependency is bumped, and the required checks pass.

Update docs/README.md with the removed adapter path.

docs/README.md still marks this page as a draft and points to ../oauth/scalekit.ts, but this change removes the draft notice and the local adapter. Update the docs index to reference mcp-use/oauth/scalekit; otherwise readers see contradictory status and a dead import path.

As per the supplied downstream context, the docs index still contains the old publication status and adapter reference.

Upgrade mcp-use to 2.3.0.

mcp-use@2.1.0 does not export mcp-use/oauth/scalekit, so index.ts cannot resolve the import. Update package.json and package-lock.json to 2.3.0, then run type checking and test Inspector login with whoami. Keep the README instructions aligned with this release.
