What is the issue?

ollama launch claude-desktop writes a configuration that references a non-existent npm package, causing the Claude Desktop integration to fail silently.

Environment:

  • OS: macOS
  • Ollama version: 0.23.1
  • Claude Desktop version: 1.6259.1(5095e7)

Steps to reproduce:

  1. Set valid OLLAMA_API_KEY for Ollama Cloud
  2. Run ollama launch claude-desktop --yes
  3. Check generated config at ~/Library/Application Support/Claude/claude_desktop_config.json
  4. Config references npx -y mcp-server-ollama
  5. Verify package doesn't exist: npx -y mcp-server-ollama returns npm 404

Expected behavior:

  • Claude Desktop should show Ollama Cloud models in dropdown
  • MCP server should successfully connect

Actual behavior:

  • Empty model dropdown (only "Legacy Model" visible)
  • MCP server silently fails to load (package doesn't exist)

Relevant log output

npm error 404 Not Found - GET https://registry.npmjs.org/mcp-server-ollama
