Which plan includes MCP access?

Signal8 Pro, at $59/mo or $588/yr.

What is the Signal8 MCP server URL?

https://mcp.signal8.ai/mcp. It is hosted, so there is nothing to install.

Connect Signal8 to Cursor

Add the hosted Signal8 MCP server to Cursor with one click or through ~/.cursor/mcp.json, then use Signal8's SEC filing, insider, dilution and market tools from the editor.

Setup

Add to Cursor

One-click: opens Cursor and adds the hosted server. After install, replace sk_live_YOUR_KEY with your API key in Cursor's MCP settings.

Or add it to ~/.cursor/mcp.json:

~/.cursor/mcp.json

{
  "mcpServers": {
    "signal8": {
      "type": "http",
      "url": "https://mcp.signal8.ai/mcp",
      "headers": {
        "Authorization": "Bearer sk_live_YOUR_KEY"
      }
    }
  }
}

Then ask

Once connected, Cursor can call any of the 113 Signal8 tools. Ask in plain English and it picks the right one.
