Other MCP clients

Auxilian works with any MCP client that supports the Streamable HTTP transport and OAuth 2.1 authorization. Every client uses the same server URL:

https://mcp.auxilian.ai/mcp

The first time a client connects, it opens a browser window where you sign in with Google and approve access. You never paste an API key.

Client setup

Claude Code
Cursor
VS Code
Other clients

Add the server from your terminal:

claude mcp add --transport http auxilian https://mcp.auxilian.ai/mcp

Then start Claude Code, run /mcp, select auxilian, and choose Authenticate to sign in and approve.To make the server available in every project, add --scope user to the claude mcp add command.

Add Auxilian to ~/.cursor/mcp.json (all projects) or .cursor/mcp.json (one project):

mcp.json

{
  "mcpServers": {
    "auxilian": {
      "url": "https://mcp.auxilian.ai/mcp"
    }
  }
}

Open Cursor Settings > MCP and select Connect or Login next to auxilian to sign in and approve.

Add Auxilian to .vscode/mcp.json in your workspace:

.vscode/mcp.json

{
  "servers": {
    "auxilian": {
      "type": "http",
      "url": "https://mcp.auxilian.ai/mcp"
    }
  }
}

Select Start above the server entry. VS Code prompts you to sign in and approve.

Configure a remote MCP server with:

Setting	Value
Transport	Streamable HTTP
URL	`https://mcp.auxilian.ai/mcp`
Authentication	OAuth 2.1 (discovered automatically)

Leave client ID and secret empty. Auxilian supports Client ID Metadata Documents and dynamic client registration, so the client registers itself. See Authorization for the endpoints.

Client menus change between releases. If a step above doesn’t match what you see, follow your client’s documentation for adding a remote MCP server with OAuth.

Requirements for client developers

If you are building an MCP client, Auxilian expects:

Streamable HTTP. The server is stateless and returns JSON responses. It does not issue session IDs or stream responses over SSE.
OAuth 2.1 with PKCE (S256). Discover the authorization server from the protected resource metadata. See Authorization.
A browser for sign-in. The user signs in with Google and approves on a consent page. Embedding these pages in a frame is blocked.
