USERDATA

The tools exist. The user has no data store. USERDATA is that store.

A logged-in Yahoo Finance account remembers your history, screens and watchlists. USERDATA is that account for equity research done with Claude, built properly: one MCP server that keeps every session, preference, skill, tag, custom XBRL concept, watchlist, peer group, note, thesis and research step, plus every number and filing pulled from SEC EDGAR and Yahoo Finance, with each number traceable to the filing it came from.

Status

v1 works: 23 MCP tools over two stores, pulling real SEC and Yahoo data. Every file is under 150 lines and passes Google's pylint, pyrefly and dbt's SQLFluff rules.

Related MCP server: open-finance-mcp

Run

cp userdata.example.toml userdata.toml   # edit paths and contact
make setup test lint
USERDATA_CONFIG=$PWD/userdata.toml uv run userdata serve          # stdio
USERDATA_CONFIG=$PWD/userdata.toml uv run userdata serve --http   # HTTP

Sources

Built on edgartools (MIT) and yfinance (Apache-2.0). Arelle (Apache-2.0) validates custom taxonomies and builds the iXBRL viewer.
