Japan Finsight

Connect Claude

Two ways to use Japan Finsight with Claude: Claude.ai (remote MCP, no install) and Claude Desktop (local app, slightly more setup).

Claude.ai (remote MCP)

Recommended for most subscribers. Nothing to install. The remote MCP endpoint launches when remote-HTTP MCP support ships. See the changelog for current status.

  1. Go to Claude.ai settings → Connectors → Add custom connector
  2. Server URL: https://japanfinsight.com/mcp
  3. Auth: Bearer token (your API key from the welcome email)
  4. Save and connect. Tools appear in any new conversation.

Claude Desktop (local app)

Available now. Requires editing one config file.

  1. Locate your Claude Desktop config:
    • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
    • Windows: %APPDATA%\Claude\claude_desktop_config.json
  2. Add Japan Finsight under mcpServers:
{
  "mcpServers": {
    "japan-finsight": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://japanfinsight.com/mcp"],
      "env": {
        "MCP_API_KEY": "your-api-key-from-welcome-email"
      }
    }
  }
}
  1. Quit Claude Desktop completely (Cmd-Q on macOS) and reopen.
  2. Open a new conversation. You should see Japan Finsight tools in the tool picker.

Verify the connection

Try this prompt in Claude:

"Use Japan Finsight to find the latest annual financials for Toyota."

Claude should call find_companies("Toyota") followed by get_financials(...) and return a 7-year financial summary.
