Why MCP Clients Matter
By Angie Jones
Why MCP Clients Matter
Most conversations about the Model Context Protocol focus on servers. But it's the clients that ultimately determine how MCP is experienced, adopted, and pushed forward. From the start, goose served as the open source reference client that made MCP real, but its role didn't stop there. By experimenting in the open, goose highlighted gaps and surfaced new patterns that now guide server design and influence other clients. This talk makes the case that clients aren't just passengers in the MCP ecosystem, they lead the movement. We'll explore how MCP clients shape usability, drive standards, and chart the direction for the future of MCP.
