Description

This MCP server wraps the Buffett Code API and exposes many ready-to-use tools for fetching company, stock, and financial-statistics data for both the Japan and US markets. It provides endpoints for daily, quarterly, monthly and weekly data, KPIs, market reaction analysis, long-form disclosure text, major shareholders, segments, guidance revisions, and company similarity searches. The server is intended to be run alongside an MCP-capable agent (for example Claude Desktop) so agents can call Buffett Code data directly during conversations or automated workflows.
