cachly — memory for coding agents
This gives your AI coding assistants a persistent memory layer across sessions. Instead of re-explaining your project setup or architectural decisions every time you start a new chat, it stores context, learns from past interactions, and surfaces relevant information through semantic search. Works with Claude, Cursor, GitHub Copilot, and Windsurf. Think of it as building up a knowledge base that remembers your coding patterns, project-specific lessons, and technical decisions so you're not constantly repeating yourself. Useful if you're working on long-running projects where context accumulates or juggling multiple codebases that share similar patterns.

Readme
cachly — memory for coding agents (MCP server)
Solve it once. From then on, your AI knows.
Every fix, decision and dead end becomes a lesson. Your AI finds it again when the same problem comes back, in the next session, in another editor, or on a teammate's machine.
