coursera

### MCP server URL or name

Coursera (directory connector) — https://api.coursera.com/mcp

### How are you connecting to this server?

From browsing the MCP server directory

### Where does the issue occur?

When pressing the Connect button

### When did you last reproduce this?

2026-07-25, Europe/Paris

### Browser and OS

_No response_

### Describe the issue

Connecting the Coursera connector fails at the OAuth step. Clicking Connect
immediately returns an error stating that automatic client registration is not
supported by Coursera, and inviting me to add an OAuth Client ID in the connector
settings. The connector never authenticates.

The suggested workaround is not actionable for a standard user account. Coursera
offers no self-serve way to mint an OAuth client_id scoped to its MCP server. The
legacy developer console only issues credentials for the old Coursera API, and the
enterprise developer portal uses a client_credentials grant, which Claude connectors
do not support.

### Error details

```shell
"L'enregistrement automatique du client n'est pas pris en charge par Coursera.
Modifiez le connecteur et ajoutez un OAuth Client ID. Si le problème persiste,
partagez cette référence avec le support : ofid_4b9d36c4ed9675b9"

Error ID: ofid_4b9d36c4ed9675b9
```

### Expected behavior

Clicking Connect completes the OAuth flow and the Coursera connector reaches
"Connected" and exposes its tools.

### Additional context

Same error family as #489 (ActiveCampaign) and #413. In all three cases the pop-up
suggests adding an OAuth Client ID for a provider that gives users no way to create
one. Is registration failing on Anthropic's connector backend, or is Claude
surfacing a provider-side DCR failure? And how is a user supposed to supply a
pre-registered client_id for a directory connector?
