Everything I've published.

Every package and MCP server under my own accounts, with links. Generated from the npm, crates.io and GitHub APIs on 2026-08-11 — not hand-maintained, so it can't drift from what's actually live.

78 MCP servers built, 26 of them public. The other 52 are private — client work, internal tooling, and unreleased builds. Only the public ones are listed below, so if you count this page you'll get 26, not 78. Both numbers are stated deliberately.

The npm packages sit across three maintainer accounts (purplesquirrel, expertvagabond, mkarsten) for historical reasons, which is why no single npm profile shows the full count. They're all listed together below.
