Implement OAuth 2.1 / OIDC authentication using Better Auth with MCP assistance. Use when setting up a centralized auth server (SSO provider), implementing SSO clients in Next.js apps, configuring PKCE flows, or managing tokens with JWKS verification. Uses Better Auth MCP for guided setup. NOT when using simple session-only auth without OAuth/OIDC requirements.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Better Auth OAuth/OIDC
Implement centralized authentication with Better Auth - either as an auth server or SSO client.
## MCP Server Setup
Better Auth provides an MCP server powered by Chonkie for guided configuration:
```bash
claude mcp add --transport http better-auth https://mcp.chonkie.ai/better-auth/better-auth-builder/mcp
```
Or in `settings.json`:
```json
{
"mcpServers": {
"better-auth": {
"type": "http",
"url": "https://mcp.chonkie.ai/better-auth/better-auth-builder/mcp"
}
}
}
```
### When to Use the MCP
| Task | Use MCP? |
|------|----------|
| Initial Better Auth setup | Yes - guided configuration |
| Adding OIDC provider plugin | Yes - generates correct config |
| Troubleshooting auth issues | Yes - can analyze setup |
| Understanding auth flow | Yes - explains concepts |
| Writing custom middleware | No - use patterns below |

How to install
mdr add mjunaidca/mjs-agent-skills/configuring-better-auth@sha256:6b7a588aa8e7d60dThe line at the top of this page pins the label git:20251222.3cc0c3c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
