Could a Claude Code routine watch my finances?

Matt May used Claude Code routines with his Driggsby MCP server and Plaid to automate a daily finance email; he says the project took 2 months and about 75k lines of Rust. The post says the Gmail connector can only create drafts, so he added a restricted `email_me()` MCP tool that sends Markdown-only mail to a verified owner address. The practical angle is operability: routine behavior changes via prompt edits, and he already runs alerts on 7-day card anomalies and daily checking outflows over $500.

Why it matters: This is a strong first-person implementation write-up: Claude Code routines + Plaid, Gmail draft-only limits, a constrained email tool, and concrete anomaly rules. HKR-H/K/R all pass, but it is still a single product blog post rather than a lab or platform release, so it lands in
