MCP Patterns Cut 42 Connections to 13 for Cross-App Automation

Summary
A new MCP guide argues the protocol becomes useful when one agent spans multiple apps—such as pulling a Gmail receipt, logging into Benepass, uploading the file and submitting the expense.
The article says the main scaling problem is configuration: 7 clients × 6 servers creates 42 connections, while an aggregated MCP server can reduce that to 13 by centralizing endpoints and authentication.
Remote-first deployment is presented as the practical path for teams, using wrappers to turn local single-user servers into multitenant remote services and installation tools to generate client-specific setup links.
For gaps where no clean MCP server exists, the guide recommends browser or computer-use fallbacks, plus local tunnels for machine-bound tools so phone or web clients can still trigger laptop-based workflows.
The piece also warns that naive tool calling can waste tokens—one workflow fell from 150,000 to 2,000—and suggests code execution, CLI wrappers and truncated search responses to control context bloat.
