A reachable endpoint is separate from installing its configuration in your agent.

Tools

Try asking your agent

• Find a Helios data table with sorting, selection and loading/error recovery.
• Retrieve the React source, dependencies and typed props for a chart before using it.
• Compose a project workspace from the shared exports and verify keyboard and reduced-motion behavior.

These are prompts to use in a connected coding agent. This page does not execute an agent or install source into your project.

Monorepos and custom aliases

The generated command points to this checkout’s MCP server. Keep that checkout available when starting a configured client. Source retrieval returns files; your agent must choose the correct application workspace, preserve its import aliases and install the declared dependencies.

Always-on design rules

Read the resolved semantic tokens alongside source and props. Shared components, keyboard focus, error recovery and reduced motion belong in the implementation. Figma mappings identify previously recorded relationships; they do not authorize Figma edits or assert that every extension has a Figma master.

This local preview exposes its included source without paid-license activation. INR plan previews keep checkout closed. A hosted paid service would require separate server-side identity and license checks.

Local transport and privacy

The server supports stdio and a loopback HTTP endpoint. HTTP checks validate the host and supported local origins. The local implementation reads allowlisted source/build files and does not collect analytics or call an inference provider. Connecting it to your coding client may send retrieved source through that client’s configured service.

This is the Helios MCP protocol implementation; a shadcn installer or another component registry does not substitute for these tools. A reachable local endpoint confirms server availability, not successful configuration of an external client.
