About mcpfold

mcpfold is a free, open-source CLI that gives you one source of truth for your MCP servers — one canonical config, folded out to every client — so you stop hand-editing a different file for each tool.

The mission

Every MCP client keeps its servers in its own file and its own shape, and every server dumps its full tool schema into the model’s context whether you use it or not. mcpfold exists to fix both: own one neutral, portable mcp.config.jsonc format that renders to every client, and curate the tools that load so you stop paying the context-window tax. Secrets stay as references, never values.

Open source, with a clear line

The CLI and everything local — the config format, the adapters, the proxy, secret resolution — are free forever and MIT-licensed. There is no paid tier hiding local features behind a login.

The only commercial surface is the optional hosted team cloud — shared configs, an audit trail, and managed sync — which you can also self-host for free. Even then, only config with secret references is ever synced; secret values never leave your machine. mcpfold stays local-first and is deliberately not a hosted enterprise MCP gateway.

Get involved

mcpfold is built in the open and adding a client is a one-PR job — the fastest way to help is to contribute an adapter for a client you use (there’s a mcpfold scaffold-adapter command to start you off).
