VELKIN

MCP servers

Connect Cursor, VS Code, or Claude to https://mcp.velkinui.com/mcp — or run @velkin/mcp locally.

Connect in 30 seconds

Point any MCP client at the hosted Velkin server. No npm install. Agents then read live component docs instead of inventing props.

{
  "mcpServers": {
    "velkin": {
      "url": "https://mcp.velkinui.com/mcp"
    }
  }
}

AI docs: MCP · AGENTS.md · Cursor skill · llms.txt

Wire your IDE

IDEConfig fileOne command
Cursor.cursor/mcp.jsonnpx velkin-mcp init --client cursor
VS Code.vscode/mcp.json (servers key)npx velkin-mcp init --client vscode
Claude Desktop / Code.mcp.jsonnpx velkin-mcp init --client claude
Other MCP clientsSame URL in that client's MCP settings—

Cursor's init also writes AGENTS.md and a Cursor skill. VS Code uses "servers" instead of "mcpServers":

{
  "servers": {
    "velkin": {
      "url": "https://mcp.velkinui.com/mcp"
    }
  }
}

What agents should call

  1. suggest_component / velkin_components — find a component
  2. get_velkin_component_docs with compact: true — props, events, slots
  3. get_component_usage or get_recipes — starter code
  4. validate_component_usage then velkin_lint — before shipping

Also useful: diff_component_migration, get_theme, get_a11y_guide, get_project_guide. Put standing rules in AGENTS.md.

When you need the npm package

Most teams only use the remote URL. Install @velkin/mcp when you need offline stdio, to pin a version, or to run init / --health.

{
  "mcpServers": {
    "velkin": {
      "command": "npx",
      "args": ["-y", "@velkin/mcp"]
    }
  }
}
npm install -D @velkin/mcp @velkin/ui
npx velkin-mcp --health
npx velkin-mcp init --client all --force
Local stdio needs peer @velkin/ui for the docs snapshot. The hosted URL does not.

Common problems

SymptomFix
Tools missing in the IDEConfirm the URL is https://mcp.velkinui.com/mcp, reload MCP, or re-run init --force
velkin-mcp --health failsInstall peer @velkin/ui, or switch to the remote URL
Agent invents propsRequire get_velkin_component_docs in AGENTS.md / skill; run velkin_lint
No MCP in the chat productUse llms.txt instead
