1️⃣ Claude Tops Finance Benchmark With 10 New Agent Templates
- What: Anthropic released 10 ready-to-deploy agent templates for financial services on May 5, covering pitchbook generation, KYC screening, month-end close, and more — alongside Microsoft 365 add-ins and a Moody's MCP app.
- Why it matters: It turns months of custom integration work into days, giving banks, insurers, and PE firms production-ready AI workflows without building from scratch.
- Key number: Claude Opus 4.7 leads the Vals AI Finance Agent benchmark at 64.37%, ahead of all other models tested on a 537-question dataset built with Stanford researchers and a Global Systemically Important Bank.
The templates package three components: skills domain knowledge and instructions, connectors governed data access, and subagents specialized Claude instances for subtasks. Each deploys as a plugin in Claude Cowork or Claude Code, or as a cookbook for Claude Managed Agents. The ten templates cover: Pitch builder, Meeting preparer, Earnings reviewer, Model builder, Market researcher, Valuation reviewer, General ledger reconciler, Month-end closer, Statement auditor, and KYC screener.
Eight new data connectors launched simultaneously: Dun & Bradstreet, Fiscal AI, Financial Modeling Prep, Guidepoint, IBISWorld, SS&C IntraLinks, Third Bridge, and Verisk. The headline addition is a Moody's MCP app that surfaces proprietary credit ratings and data on over 600 million public and private companies directly inside Claude conversations.
Claude now runs inside Excel, PowerPoint, and Word via new Microsoft 365 add-ins, with Outlook support listed as
