# MCP Connect: Auto-Connect Unavailable

> POST /mcp-connections could not auto-connect the server — it does not expose OAuth Dynamic Client Registration.

**HTTP status:** 400

## Error message

```
{server} does not support Dynamic Client Registration, so it can't be connected automatically.
```

(or, when no OAuth metadata is found at all: "Could not discover the server's OAuth authorization metadata.")

## When this error occurs

`POST /mcp-connections` only performs **self-service OAuth via Dynamic Client Registration (DCR)**. It probes the
server for authorization metadata (PRM / RFC 9728 → RFC 8414 → OIDC discovery) and a `registration_endpoint`. You get
this error when that can't be resolved — either the server isn't an OAuth-protected resource, or it advertises OAuth but
not DCR.

## You may not need a connection at all

If the error notes that tools are available without authorization — e.g. *"3 tool(s) are available without
authorization"* — the server is usable **open**: skip the connection entirely and add its URL to `mcp_servers[]` with
**no** `connection_id`. Some servers (Mintlify-hosted docs MCPs, for example) are open by default and only enable DCR
when they host gated content.

## How to fix

* Only need the open tools? Add the URL to `mcp_servers[]` without a `connection_id`.
* If the server requires auth but only registers clients manually (static client id/secret), that flow isn't supported
  here — obtain access out of band.
* If you expected auto-connect, confirm the server implements OAuth DCR per the
  [Model Context Protocol](https://modelcontextprotocol.io/) authorization spec.
