We offer a set of open-source plugins that extend Claude Cowork with specialized capabilities for financial services workflows, including financial modeling, equity research, investment banking, private equity, and wealth management.
These plugins are available in a public GitHub repository that you can add as a marketplace in Claude Cowork.
What's included
The repository contains a core plugin and several add-on plugins that build on it:
- Financial analysis (core) — Build comparable company analyses, DCF models, LBO models, and 3-statement financials. This plugin also includes all shared MCP connectors for financial data providers. Install this first.
- Investment banking — Draft CIMs, teasers, and process letters. Build buyer lists, run merger models, and create strip profiles.
- Equity research — Write earnings updates and initiating coverage reports. Track catalysts and screen for new ideas.
- Private equity — Source and screen deals, run due diligence checklists, draft IC memos, and monitor portfolio company KPIs.
- Wealth management — Prep for client meetings, build financial plans, rebalance portfolios, and identify tax-loss harvesting opportunities.
The repository also includes partner-built plugins from LSEG and S&P Global, which bring their financial data and analytics directly into Cowork.
