mcpfold is a local-first CLI + proxy that curates your MCP servers. Write config once, fold it out to every client (Claude, Cursor, VS Code, Windsurf), load only the tools each agent needs, and resolve secret references instead of hardcoding keys.

Hey Product Hunt 👋 I built mcpfold to fix something that bugged me about MCP: every server yo connect dumps its _entire_ tool schema into your agent's context on every turn — whether the agent uses those tools or not. That's a silent tax on every request. mcpfold is a local-first CLI + proxy. You write one canonical config, and it folds out to every client (Claude Desktop, Cursor, VS Code, Windsurf…), curating the toolset per client so each agent only sees the tools it needs — ~80% fewer tool-schema tokens in a reproducible benchmark. It also resolves secret _references_ at sync time, so keys never get hardcoded across a dozen config files. Free forever, MIT-licensed. The optional cloud (sync, teams) is self-hostable. Would love your feedback — especially which clients/servers you'd want supported next.

how does the secret resolution actually work under the hood, like is it pulling from a local vault or hooking into something like 1password and how does that play with clients that expect raw env vars
