Become a sponsor to Casey Hand
Hi, I'm Casey.
I build open source TypeScript tooling for connecting LLMs to the real world — a framework called mcp-ts-core, plus a set of MCP servers, many hosted free to use at *.caseyjhand.com.
If my work has helped you, please consider sponsoring. Thanks to everyone who contributes & sponsors.
See github.com/cyanheads for the full list. Currently open to work — AI/LLM tooling and infrastructure.
