Rockmoon — Cross-Market Financial Data for AI Agents (MCP)

English · 中文 · 한국어 · 日本語 Rockmoon is an MCP server that gives your AI agent clean, cross-market (US / Japan / Korea) financial data — financials, segments, ownership, valuation metrics and prices — where every value traces back to its source filing (SEC / EDINET / DART). > One API key works for both REST and MCP. Built MCP-native, so Claude, Cursor, and any MCP client can call it directly. - Endpoint: https://mcp.rockmoon.ai/mcp (Streamable HTTP) - Auth: X-API-Key: <your key> header (also accepts Authorization: Bearer <key>) - Get a key: https://rockmoon.ai - Official MCP registry: ai.rockmoon/financial-data

Why Rockmoon

| | Rockmoon | Typical "global" data APIs | | ------------------------------ | --------------------------------------- | -------------------------- | | Asia depth (JP / KR) | Deep, cleaned, filing-grade | Shallow / auto-aggregated | | Provenance | Every value traces to the source filing | Rarely | | MCP-native | Yes — agents call it directly | Mostly REST-only | | Cross-market comparability | One canonical 80-field schema | Per-vendor mess | Most "global" data is wide but shallow in Asia. Rockmoon is the opposite: deep, clean, comparable Asia + US data your agent can cite.

Quickstart

Add to your MCP client config (Claude Desktop, Cursor, etc.): ``

json
{
  "mcpServers": {
    "rockmoon": {
      "type": "http",
      "url": "https://mcp.rockmoon.ai/mcp",
      "headers": { "X-API-Key": "<YOUR_ROCKMOON_API_KEY>" }
    }
  }
}



Then just ask:

- "Compare gross margins of AAPL, 7203 (Toyota) and 005930 (Samsung)."
- "Screen US semiconductors by ROE."
- "Show Toyota's revenue by segment over the last 5 years."
