Connect a Client - Parallax API

The Parallax MCP server is a remote server that speaks Streamable HTTP at:

https://mcp.chicago.global/api/mcp

Point any MCP-capable client at that URL. On first connection the client opens a browser window for a one-time Parallax sign-in (OAuth) — after that, your assistant can call Parallax tools directly. See Authentication for details.

Claude

Claude (web & desktop) connector
Claude Desktop config (mcp-remote)

In Settings → Connectors → Add custom connector, give it a name (e.g. Parallax) and paste the server URL:

https://mcp.chicago.global/api/mcp

Approve the browser sign-in when prompted. The Parallax tools then appear in the tools menu of any chat.

If you configure Claude Desktop by file, bridge the remote server with mcp-remote in claude_desktop_config.json:

{
  "mcpServers": {
    "parallax": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://mcp.chicago.global/api/mcp"]
    }
  }
}

Restart Claude Desktop; a browser window opens for sign-in on first use.

Cursor

Add the server to ~/.cursor/mcp.json (global) or .cursor/mcp.json (per-project):

{
  "mcpServers": {
    "parallax": {
      "url": "https://mcp.chicago.global/api/mcp"
    }
  }
}

Open Settings → MCP, confirm Parallax is listed, and complete the sign-in prompt.

VS Code

With MCP support (GitHub Copilot agent mode), create .vscode/mcp.json:

{
  "servers": {
    "parallax": {
      "type": "http",
      "url": "https://mcp.chicago.global/api/mcp"
    }
  }
}

Reload the window and start the server from the MCP view; authorize when prompted.

ChatGPT

In Settings → Connectors (developer mode), add a remote MCP server with the URL https://mcp.chicago.global/api/mcp and authorize access. Parallax tools become available to the model in chat.

Any other MCP client

Any client that supports remote MCP servers can connect with the same URL. For clients that only support local stdio servers, bridge with mcp-remote:

npx -y mcp-remote https://mcp.chicago.global/api/mcp

Prefer the Streamable HTTP endpoint (/api/mcp). Use the legacy SSE endpoint (https://mcp.chicago.global/api/sse) only if your client doesn’t yet support Streamable HTTP.

Verify the connection

Once connected, ask your assistant something like “Use Parallax to give me a peer snapshot of MSFT.O” or “List the Parallax macro countries.” If the tools are wired up correctly, the client will call get_peer_snapshot / list_macro_countries and return live data. Browse everything available in the tool reference.
