The full upstream README, mirrored here for reference. Install config, tool schemas, adoption signals, and an original overview live on the BrainCloud MCP Helper listing page.
A local, trustless MCP server that lets AI coding assistants (Claude Code, Cursor, Codex, …) sync brainCloud cloud-code scripts to and from your filesystem and git repo.
It never authenticates to brainCloud on its own and stores no credentials. Every Builder API call
is driven by a short-lived, app-scoped ticket that the AI obtains from the hosted
braincloud-mcp's getSyncTicket tool and passes in — script content flows helper → Builder API
directly, never through the AI's context.
This is an npm workspace with two packages:
| Package | What it is |
|---|---|
@braincloud/mcp-helper | The MCP server itself — status / pull / push / sync tools, installable via npx -y @braincloud/mcp-helper@latest. |
@braincloud/cloudsync-core | Host-agnostic sync/format logic (the .ccjs / .bcsync / .bcsync.local on-disk contract) shared with the VS Code extension. |
See each package's README for tool details, configuration, and the on-disk format.
