Language models are strong at reasoning, but without tools, they can only talk - not act. For financial applications requiring precise calculations, real-time data access, or system integrations, tool-augmented agents are essential. Combined with structured outputs using Pydantic, we can build reliable financial systems that guarantee data format compliance.
Summary: Google's Agent Tools & MCP Interoperability
Following our coverage of Google’s Introduction to Agents, this post dives into the companion whitepaper on Agent Tools and Model Context Protocol (MCP). While the first paper covered agent architecture, this one focuses on how agents interact with the world through tools and the emerging interoperability standard.

Summary: Google's Introduction to Agents
As part of our journey exploring agentic AI systems, Google’s November 2025 whitepaper “Introduction to Agents” offers valuable industry perspective on production-grade agent architecture. This post summarizes the key concepts: core architecture, Agent Ops, security patterns, and self-evolving systems. It complements what we’ve covered in our Agentic AI series.

Orchestrating Financial Operations
When financial workflows become too complex for simple parallel processing or chaining, the orchestrator-worker pattern provides dynamic coordination. Unlike fixed workflows, an orchestrator analyzes problems at runtime, breaks them into subtasks, and delegates work to specialized agents. This is the pattern that ties together everything we’ve learned - bringing intelligent coordination to financial operations.
Parallel Processing and Quality Control in Finance
Financial analysis often requires examining multiple dimensions simultaneously - market data, sentiment, risk factors, regulatory compliance. Rather than processing these sequentially, parallel workflows distribute work across multiple agents for speed and diverse perspectives. Combined with evaluator-optimizer patterns for quality assurance, these techniques form the backbone of production-grade financial AI systems.
Prompt Chaining and Routing in Trading Systems
Trading systems process diverse request types - market orders, limit orders, options, compliance checks - each requiring specialized handling. Two fundamental patterns enable this: prompt chaining for sequential multi-step processing, and routing for intelligent task distribution. Mastering these patterns is essential for building robust financial workflows.
Modeling Agentic Workflows for Finance
Moving from individual prompts to production systems requires thinking architecturally. Financial workflows aren’t just chains of prompts - they’re coordinated systems where multiple specialized agents work together. Understanding how to model these workflows is essential for building reliable, maintainable financial AI systems.
Building Financial Prompt Pipelines
Once you have effective prompts for individual tasks, the next challenge is connecting them into reliable workflows. Financial services demand more than single-shot responses - they require multi-stage pipelines with validation at every step. Prompt chaining and feedback loops are the mechanisms that transform individual prompts into robust, production-ready systems.
