mcp-ui vs remote-dom
MCP tool interfaces and sandboxed UI synchronization compared
mcp-ui provides SDKs for attaching web interfaces to Model Context Protocol tools and rendering them in compatible hosts. remote-dom synchronizes a UI tree from a sandboxed JavaScript environment into a host page, so it is a broader mechanism for controlled host-rendered interfaces rather than an MCP-specific toolkit.
mcp-ui: Build Interactive Interfaces for MCP Tools
mcp-ui provides SDKs for attaching web interfaces to Model Context Protocol tools and rendering them in compatible hosts. Use it when an MCP server needs interactive, sandboxed UI alongside tool results.
remote-dom: Synchronize Sandboxed UI with a Host Page
Remote DOM mirrors a UI tree created in a sandboxed JavaScript environment into a host page. It suits teams that need to isolate remote code while limiting which elements and interactions that code can expose.

Key differences
- mcp-ui targets MCP servers and hosts, linking tools to UI resources through the MCP Apps standard; remote-dom synchronizes a DOM-like tree between JavaScript environments.
- mcp-ui includes TypeScript, Ruby, and Python server SDKs plus a TypeScript client SDK; remote-dom provides TypeScript packages and companion packages for React, Preact, and signals.
- mcp-ui includes renderers for MCP Apps and legacy MCP-UI resources; remote-dom provides a DOM receiver and policies for controlling remote elements, attributes, events, and methods.
- mcp-ui is licensed under Apache-2.0, while remote-dom is licensed under MIT.
- mcp-ui reports 5.2k stars and 400 forks; remote-dom reports 1.3k stars and 92 forks.
Choose mcp-ui if you…
- need to attach interactive UI resources to MCP tools.
- want server SDK options in TypeScript, Ruby, or Python, or a TypeScript client renderer.
- are building an MCP host that supports MCP Apps or legacy MCP-UI resources.
Choose remote-dom if you…
- need to synchronize a UI tree from sandboxed JavaScript into host-rendered elements.
- want host policies to restrict remote elements and their attributes, events, and methods.
- are building plugin interfaces or running UI-producing JavaScript in a Web Worker.
