Best MCP servers for frontend in 2026 (9 tools)

An MCP server for the frontend gives the agent component records, screenshots and page data without copy and paste. The EneUI server exposes 9 tools in read-only mode, counted in backend/mcp.js on 1 November 2026.

What the number means

9 is the number of tools registered in the TOOLS array of backend/mcp.js, not the number of endpoints. Each tool has an input schema and returns text: the server writes no file, spends no quota and touches no account.

How to choose an MCP server

• Prefer read-only: a server that writes files should be limited to one directory.
• Check the transport: stdio for a local process, Streamable HTTP for a remote endpoint.
• Count the token cost: every result goes back into the context and is paid for.
• Read the licence of the server, not of the catalogue it queries.
• Check the rate limit before you wire it into a CI pipeline.

The catalogue record

The server returns records such as agent-dock: MIT licence, 468 stars declared upstream on 1 November 2026, page URL and install command. Neighbouring records sit in the agent category and in the AI Elements library.

How to query it

curl -s https://ui.eneawork.it/mcp \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

The response lists the 9 tools with their description and input schema. A client such as Claude Code makes the same call, so the number you read here is the number the agent sees.

The limitation

The public endpoint is anonymous and limited per IP to 120 requests per minute: an agent that explores in parallel reaches the ceiling at once. Commercial libraries return metadata, but the install command only arrives with a paid plan.

Where to continue

Configuration for the three editors is in shadcn MCP in Claude Code, Cursor and VS Code, the protocol itself in what MCP is. For the comparison between shipping code and shipping a package read copy-paste or headless.
