platter

*Your computer, served on a platter.*

MCP server that exposes Read, Write, Edit, and Bash tools over Stdio and StreamableHTTP transports. Built with Bun, compiles to standalone executables with zero runtime dependencies.

Designed to be used by browser-based (or any MCP-compatible) agents — like Hadrian — to control a computer.

| Tool | Description | |------|-------------| | read | Read file contents with pagination (offset/limit). Truncates at 2000 lines or 50KB. | | write | Create or overwrite files. Auto-creates parent directories. | | edit | Find-and-replace with exact (or fuzzy Unicode) matching. Requires a unique match. Returns a unified diff. | | bash | Execute shell commands with optional timeout. Output truncated to last 2000 lines or 50KB. |

Download the binary for your platform from Releases, make it executable, and run:

chmod +x platter-linux-x64
./platter-linux-x64                        # stdio mode
./platter-linux-x64 -t http               # HTTP mode on :3100

bun install
bun run dev                                # run directly from TypeScript
bun run compile                            # build standalone binary for current platform
