Description

SageFs is a live F# engine that runs as a daemon allowing multiple editors and AI agents to connect simultaneously. It offers sub-500ms feedback on code saves with inline results, live test markers, and hot reload for web apps. The MCP server exposes a focused protocol enabling AI agents to compile, evaluate, type-check, and run tests against real projects efficiently.
