Set Up in Your IDE

Add the DepFixer MCP server to your preferred AI coding assistant in under a minute

Add to your Claude Code MCP settings ( .claude/settings.json )

.claude/settings.json
{
  "mcpServers": {
    "depfixer": {
      "command": "npx",
      "args": [
        "@depfixer/mcp-server"
      ],
      "env": {
