Problem
tools/mcp/src/main.rs registers MDDS endpoint tools off the MddsClient registry but exposes nothing for the FLATFILES surface. MCP consumers cannot pull whole-universe daily blobs through the JSON-RPC tool surface even though the Rust core supports it via ThetaDataDx::flatfile_request*.
Proposed solution
Add MCP tools mirroring the Rust unified surface:
flatfile_request — args (sec_type, req_type, date, output_path, format); returns the written path.flatfile_request_decoded — args (sec_type, req_type, date); returns rows (gate behind a row-count cap; prefer file output for whole-universe blobs).- The 9 convenience wrappers (
flatfile_option_open_interest, flatfile_option_trade_quote, flatfile_option_trade, flatfile_option_quote, flatfile_option_eod, flatfile_stock_*).
- Validate
sec_type ∈ {Option, Stock}, req_type ∈ {Trade, Quote, TradeQuote, OpenInterest, Eod}, date as YYYYMMDD, format ∈ {csv, jsonl}.
Wire registration the same way MDDS endpoints are wired today.
Impact
MCP consumers reach parity with the Rust SDK for the third public surface.
