30,000+ filers since 2009, in one schema. Your AI agent gets accurate, auditable numbers: every value traces back to the regulator's XBRL fact.
Eighteen MCP tools your agent calls directly — statements, segments, screening, holdings, comparisons — from Claude Code, Claude Desktop, Cursor, Cline, or anything that speaks MCP. Data shaped for tool calls, answers in milliseconds.
Sony files with EDINET, Apple with the SEC, Samsung with DART — three regulators, three languages, three accounting regimes. Your agent sees one schema and answers in one call.

Rockmoon is an MCP-native financial data service for AI agents. It provides fundamental data for 30,000+ listed companies across the US, Japan and Korea, with history back to 2009, extracted directly from regulator XBRL filings (SEC EDGAR, EDINET, DART). Every value is traceable to the exact fact in the original filing.
Add the Rockmoon MCP server with one command:
claude mcp add --transport http rockmoon https://mcp.rockmoon.ai/mcp
--header "Authorization: Bearer YOUR_KEY". Your agent then gets 18 tools
for financial statements, segments, screening, insider trades and holdings. Works with
Claude Code, Claude Desktop, Cursor, Cline, or any MCP client.
Yes. Rockmoon covers Japan via EDINET filings and Korea via DART filings, alongside the US via SEC EDGAR — all normalized into one 80-field schema, so an agent can compare Sony and Apple gross margins in a single query without stitching together multiple vendors.
US fundamentals go back to 2009; Japan and Korea cover roughly 10–15 years depending on the filer. Most $20–30/month data subscriptions cap history at 5 years; full-cycle analysis and backtests need more.
Yes — that is the core design. Every value carries provenance back to the source XBRL fact, and the public trace explorer at rockmoon.ai lets you click any cell and see the original filing with that exact fact highlighted. Field definitions are anchored to the official accounting specs (Reg S-X, ASC, IFRS, K-IFRS).
The free tier includes full-depth financial statements at 50 requests/day, no card required. The early-bird plan is $9.90/month (regular $19) for all data — segments, insider trades, holdings — at 60 requests/minute. Unlimited throughput and REST access are available by emailing [email protected].
Those are good free options for US tickers, but the depth is limited and there is no cross-market schema. Rockmoon parses the raw XBRL itself across three markets, audits the output against the source documents and against commercial vendors, and serves it over MCP with per-value traceability.
Business, geographic and product segment revenue with time series; US insider trades (Form 3/4/5, ingested daily — filed today, queryable tomorrow); institutional holdings (13F); and major shareholder / director holdings for Japan and Korea.
