概要

What is Rockmoon Financial Data?

Rockmoon Financial Data is an MCP server that provides AI agents with clean, cross-market financial data covering the US, Japan, and Korea. Every value traces back to its source filing (SEC, EDINET, or DART), enabling verifiable, filing-grade financials, segments, ownership, valuation metrics, and prices.

How to use Rockmoon Financial Data?

Add it to any MCP client such as Claude Desktop or Cursor by configuring a Streamable HTTP endpoint with a single API key. Use the provided JSON configuration with the URL https://mcp.rockmoon.ai/mcp and header X-API-Key (or Authorization: Bearer). Then ask natural-language queries like "Compare gross margins of AAPL, 7203 and 005930" or "Screen US semiconductors by ROE."

FAQ from Rockmoon Financial Data

How do I get an API key?

Get a free API key from https://rockmoon.ai. One key works for both the MCP endpoint and the REST API.

What markets and filing sources are covered?

The server covers US (SEC XBRL), Japan (EDINET), and Korea (DART) markets with filing-grade financial data.

How is data provenance ensured?

Every financial value traces back to the original XBRL filing with ASC, IFRS, or Reg S-X citations, accessible via the REST /v1/trace/ endpoint.

What MCP clients are supported?

How does Rockmoon differ from typical global data APIs?
