filingrail-mcp

Every number a public company reports to the SEC is free and open on EDGAR. The bottleneck isn't access — it's the XBRL parser, the tag-drift normalizer, the rate-limit governor, and the dedup layer you'd have to write before you get the one figure you actually wanted.filingrail-mcphands your agent the finished JSON instead.

- Source-traceable.Every financial response carries the originatingsource_filing_url. Click it, see the exact 10-K / 10-Q on sec.gov. No "trust us."
- Normalized.revenueisrevenue, whether the filer tagged itus-gaap:Revenues,SalesRevenueNet, orRevenueFromContractWithCustomerExcludingAssessedTax. 1.8M+ XBRL rows back to 2006.
- Zero plumbing.No EDGAR User-Agent config, no local parser, no rate-limit governor. The API handles all of it.

Filingrail is a REST API on RapidAPI. The free tier is50 calls/day, no credit card:

The end user brings their own key — set it asRAPIDAPI_KEYin your MCP client config (below).

Edit%APPDATA%/Claude/claude_desktop_config.json(Windows) or~/Library/Application Support/Claude/claude_desktop_config.json(macOS):

{ "mcpServers": { "filingrail": { "command": "filingrail-mcp", "env": { "RAPIDAPI_KEY": "your-rapidapi-key-here" } } } }

Restart Claude Desktop. The Filingrail tools (search_companies,get_financials,get_insider_trades, …) appear in the tool list. Then just ask a question in plain English.

Cursor / Continue / any other MCP client

Point the client atfilingrail-mcpas the stdio command and passRAPIDAPI_KEYas an environment variable. Same shape as above.

If your client only accepts a raw command, use:

{ "command": "filingrail-mcp", "env": { "RAPIDAPI_KEY": "your-rapidapi-key-here" } }

After installing and configuring, ask your agent:

- "What was Apple's revenue and operating income last quarter, and link me the filing."
- "Show me insider sells at NVIDIA in the last 30 days."
- "What 8-K events did Tesla file this month?"
- "List Berkshire Hathaway's 10 largest 13F positions for 2026-Q1."

- Not real-time.New filings appear within ~24h of EDGAR acceptance (fair-access policy).
- Not Bloomberg.No intraday prices, options chains, non-US issuers, or analyst estimates.
- Structured SEC data, traced to source— that's the whole product.
