How to scope MCP access tokens to a specific organization?

Hello! I am using both the Organization and the MCP plugins. I would like my MCP access tokens to be scoped to a specific organization and not give access to all organizations of a user. The flow I was envisioning is to have the user login if not already the case, then go to org selection page before the authorization was done, but couldn't find how to achieve this. ...

Custom JWKS endpoint?

Hi, I've been integrating a provider (Web3Auth) and they only provide a JWKS endpoint where they return an identity token, no token/discovery/userinfo endpoints, does better-auth supports that? Seems like the generic auth kinda works with it but I can't find a way of providing a custom JWKS endpoint instead of the discovery URL.

OAuth organization integrations

Can better-auth be used to add authentications for an org (e.g. what Discord calls Integrations in Server settings)? For SaaS apps I often want to separate user login (accounts the user can sign in with) from connecting integrations (the app performs operations on behalf of the org in a 3rd party system, e.g. post a tweet). My idea was to store Organization->Integrations in a similar way as User->Accounts. Is there a better-auth function I can call to trigger OAuth from an organization context b...

How can I know more about the invalid_client Error Code?

I'm integrating the MCP plugin to my tanstack start app, I swear yesterday it was working but today I always get that invalid_client right after a successful login. I don't know where to look at, maybe a vscode update (I'm on the insiders with daily updates) or really I don't understand why it suddently stopped working. Regardless of yesterday vs today, back do the initial question, where can I know more about the invalid_client error?...

Solution:

That's great, I had deleted the oauth_application entry on my db that was generated by vscode the first time, without telling vscode to also remove it from its cache. From vscode I ran the command "Remove Dynamic Authentication Provider" and tried again my MCP server, it did again the discovery process and it know works 😄...

disableCookieCache: it doesn't refresh the cookie cache

I have a page where I have to set active organization and active team when the user goes. In auth configuration the session cookieCache is enabled and maxAge is 300. After setting the active organization and active team, I'm getting the refreshed session by using disableCookieCache: true, and log the session and I can see the active org and active team, so far so good. But when I refresh the page, the page again sets the active organization and active team because session data in cookie is not refreshed. It still has empty active org and active team. Based on doc (https://www.better-auth.com/docs/concepts/session-management#session-caching), it says disableCookieCache: true will refresh the cookie cache, but it doesn't. Am I missing a point here?...

MCP Plugin not working with MCP Inspector

Hello When running the official https://github.com/modelcontextprotocol/inspector for authentication, it is sending an OPTIONS request to the oauth registration endpoint (http://localhost:5173/api/auth/mcp/register), which is not defined by the plugin and returns a 404. On the inspector, this ends the signin flow and it's not possible to use the inspector I also noticed that the plugin is not defining a .well-known/oauth-protected-resource route, which the MCP clients are querying...
