MCP Server Working?

[Moses-Joby]

I'm running npx -y @ark-ui/mcp in my windows command prompt and then sending the example initialize message from the MCP docs and Ark UI MCP server is telling me it has no tools (see cmd prompt output below).

C:\Users\username\Documents\Code\ark-ui-mcp-wrapper>npx -y @ark-ui/mcp
Ark UI MCP Server running on stdio
{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2024-11-05","capabilities":{"roots":{"listChanged":true},"sampling":{},"elicitation":{}},"clientInfo":{"name":"ExampleClient","title":"ExampleClientDisplayName","version":"1.0.0","icons":[{"src":"https://example.com/icon.png","mimeType":"image/png","sizes":["48x48"]}],"websiteUrl":"https://example.com"}}}
{"result":{"protocolVersion":"2024-11-05","capabilities":{"tools":{"listChanged":true}},"serverInfo":{"name":"ark-ui","version":"1.0.0","capabilities":{"prompts":{},"resources":{},"tools":{}}}},"jsonrpc":"2.0","id":1}

I'm having trouble registering this MCP server in Zed (the editor) so I am testing manually like this. Anyone have a tip for me?

Tested it in Cursor, VSCode, and Claude Code. It works correctly. Perhaps it's a Zed issue?

For manual testing on Windows, I recommend using the official MCP Inspector:

npx @modelcontextprotocol/inspector npx -y @ark-ui/mcp

This provides a web UI for testing MCP servers and handles the protocol handshake automatically.

For Zed Integration

If you're having trouble with Zed specifically, make sure:

• Your Zed version supports MCP context servers
• The configuration in settings.json is correctly formatted
• Try restarting Zed after adding the configuration

Let me know if you're still having issues after trying these steps!

It seems I was having permission issues - possibly because I build Zed from source.

I also mis-understood the function of the "capabilities" section in the initialization response.

Can confirming compatibility with Zed.
