MCP server

Connect Claude, ChatGPT, Codex, Cursor, VS Code, Hermes or OpenClaw to your Sigrex account and manage strategies, bots and signals in plain language.

Sigrex hosts a remote Model Context Protocol server. MCP is an open standard that lets AI assistants use external tools. Compatible clients discover the Sigrex tools on their own and sign you in with OAuth, so there are no API keys to copy.

Server endpoint

https://mcp.sigrex.io

The server uses Streamable HTTP. The first time you connect, your client opens the Sigrex sign-in page in your browser. Log in and approve access.

⚠️ The connection has full access to your account, including placing live trades. Only connect clients you trust, and check every action before you approve it.

Connect your client

In most clients, add the URL above as a remote MCP server or custom connector, then sign in.

Claude: go to Customize → Connectors, click +, then Add custom connector, and paste the URL.

ChatGPT: turn on Developer mode under Settings → Security and login. Then go to chatgpt.com/plugins, click + and paste the URL.

Claude Code:

claude mcp add --transport http sigrex https://mcp.sigrex.io

Codex:

codex mcp add sigrex --url https://mcp.sigrex.io

VS Code, Cursor and other JSON configs:

{
  "mcpServers": {
    "sigrex": {
      "type": "http",
      "url": "https://mcp.sigrex.io"
    }
  }
}
