I Had a Working Agent at $3.41 a Run. Here's Where the Money Was Actually Going.

API → Connector → Browser → Computer Use → Human: A Cost-Justified Hierarchy for Agent Tooling
Computer use is 45× more expensive than a structured API for the same task. Eight harness configurations across browser, desktop, and hybrid showed costs from $0.03 to $5.44 on the same task — the hierarchy, the numbers, and why implementation beats model choice.

There are 58 public MCP servers in the awslabs catalog covering cloud infrastructure, databases, AI/ML, and ops tooling. Here's the enterprise pattern: proxy them locally, then host the proxy behind a gateway so every developer in your org gets them without setup.

The Missing Middle: Why AI Chiefs of Staff Fail Without Calendar Materialization
Every AI Chief of Staff tool tells you what matters. None of them answer 'when will I do it?' The gap between a morning brief and actual execution is calendar materialization — and without it, triage is noise with structure.

The Meta-Tool Pattern: Teaching Your Agent to Discover Its Own Tools
The MCP token tax has a fix. The solution isn't fewer tools — it's a smarter way to load them. Here's the pattern.

Building the MCP Proxy: What Broke and What I Changed
The proxy pattern from part two, built and debugged. Two things broke: a missing dependency that crashed startup silently, and a response format that made the model do unnecessary work.
