Reviewing Port of Context (pctx)
Bill Doerrfeld | January 26, 2026
Can a vendor-LLM-agnostic project slim MCP usage?
The more folks use MCP servers in development, the more they’re realizing it can lead to runaway token usage, unpredictable response sizes, and flooded context windows.
My latest piece for The New Stack looks at an interesting project aiming to address this problem: Port of Context.
It's an open-source LLM-agnostic equivalent to Cloudflare's Code Mode and Anthropic's code execution approach — both of which introduce a new architecture designed to dramatically optimize MCP usage.
I checked in with lead maintainer Patrick Kelly of Sideko to take a closer look at Port of Context (pctx), its benefits, early tradeoffs, and where it’s heading next.
