How it works

Three steps to cybersecurity market intelligence in your AI workflows.

1

Connect

Add The Signal's MCP server URL to Claude, Cursor, or any MCP-compatible client.

2

Authenticate

Sign in with your Signal account. A paid Pro or Enterprise subscription is required.

3

Ask questions

"Which Series B+ companies building DLP are based in the US?" — and get structured answers.

Connect the MCP PRO

In Claude or Claude Desktop, go to Settings → Connectors → Add custom connector.

Set the name to "The Signal" and paste this connector URL:

https://mcp.returnonsecurity.com/mcp

Claude will redirect you to authenticate with your Signal account.

Run this command in your terminal:

claude mcp add the-signal https://mcp.returnonsecurity.com/mcp

Claude Code will open your browser for authentication.

In Cursor, go to Settings → MCP → Add Server.

Paste the server URL:

https://mcp.returnonsecurity.com/mcp

Cursor handles authentication automatically.

Add The Signal to your MCP configuration:

{
  "mcpServers": {
    "the-signal": {
      "url": "https://mcp.returnonsecurity.com/mcp"
    }
  }
}

Use these settings for any MCP-compatible client:

https://mcp.returnonsecurity.com/mcp

Transport: Streamable HTTP

Auth: OAuth 2.1 (handled automatically by your MCP client)

MCP access requires a paid Pro ($99/mo) or Enterprise subscription. Free accounts, trials, and complimentary access do not include MCP. Upgrade to Pro →
