# Connect another MCP client

These steps apply to an AI agent or editor that supports remote MCP servers but does not have a dedicated guide here. First, choose OAuth or a personal token as described in [Before you start](../connect-ai-agents.md#before-you-start).

## Add the server

1. Open the client’s MCP server settings and add a server named `reconstruct`.
2. Select **Streamable HTTP** (sometimes labeled **HTTP** or **remote HTTP**).
3. Set the server URL to `https://reconstruct.dev/mcp`.

## OAuth browser sign-in

Use this method if the client supports a pre-registered public OAuth client and its exact callback URI has been approved. Anonymous dynamic registration is disabled. No personal token needs to be issued on the Platform.

1. Select OAuth, set client ID `reconstruct-mcp` and scopes `openid aud-mcp`, and leave the client secret empty.
2. Save the server and start its sign-in or connect action.
3. Complete Reconstruct sign-in in the browser, approve access and return to the client.

The issuer is `https://reconstruct.dev/sso/realms/reconstruct`; use its discovered authorization and token endpoints rather than constructing root `/authorize` and `/token` URLs.

Remove a manually configured `Authorization` header when choosing OAuth. If sign-in reports a callback error, [contact support](https://reconstruct.dev/support) with the callback URI shown by the client.

## Personal access token

If the client does not support OAuth, [create an MCP token](../connect-ai-agents.md#personal-access-token) in Platform settings and set the HTTP header `Authorization` to `Bearer <your MCP token>`. Use the client’s secret store or the `CR_RECONSTRUCT_MCP_TOKEN` environment variable if supported.

## Check the connection

Reconnect or restart the client. Confirm that `list_products` appears in its tool list, then ask the agent to call it.

There is no single JSON format shared by all clients. Some use `mcpServers`, others use `servers` or `mcp`; some require a `type` field. Follow your client's documentation for the exact field names and token interpolation syntax. A client that supports only the older SSE transport cannot use Reconstruct's HTTP `/mcp` endpoint as SSE.

If the connection fails, check the [troubleshooting table](../connect-ai-agents.md#troubleshooting). Once connected, try the [prompt examples](../prompt-examples.md).
