Connect Cursor

Cursor supports MCP servers configured at the workspace level. Add Japan Finsight to your .cursor/mcp.json.

You'll need your API key. It's the long string starting with jfs_ in the onboarding email the founder sends within 24 hours of your subscription. Copy it rather than retyping it. Haven't received it yet? Email data@japanfinsight.com.

Setup

In your project root, create or edit .cursor/mcp.json:

{
  "mcpServers": {
    "japan-finsight": {
      "url": "https://mcp.edinet.tools/mcp",
      "headers": {
        "Authorization": "Bearer your-api-key-from-onboarding-email"
      }
    }
  }
}

Restart Cursor (or reload the window via Cmd-Shift-P → "Reload Window").
Open Cursor's chat panel. Japan Finsight tools should be available to the agent.

Verify

In the chat panel:

"Use Japan Finsight to look up the latest cash flow for Sony."

Cursor should call Japan Finsight tools and return multi-year cash flow figures. If the tools never appear to the agent, see Troubleshooting.

Once it works, try a cross-market question:

"Which companies announced a buyback this year while a 5%+ activist holder was on the register? Use run_sql if the typed tools don't cover it."

Troubleshooting

If tools aren't appearing, check Cursor's MCP logs via Cmd-Shift-P → "MCP: Show logs". Common issues:

Authorization header typo: leading "Bearer " is required
Workspace not trusted: Cursor disables MCP in untrusted workspaces

Email data@japanfinsight.com if it's something else. The founder answers within 24 hours.

Using the Claude Desktop app as well? It connects too: see Connect Claude.
