README

@vibefix/mcp

Your AI built it. It broke. Post the bug, a real developer fixes it.

VibeFix is a bug bounty platform for vibe coders. This MCP server lets you browse bounties, post bugs, submit fixes, and run website diagnostics directly from Claude Code, Cursor, Windsurf, or any MCP-compatible client. Free to post.

Setup

1. Get an API key

2. Add to your MCP client

Claude Code (~/.claude.json):

{
  "mcpServers": {
    "vibefix": {
      "command": "npx",
      "args": ["@vibefix/mcp"],
      "env": {
        "VIBEFIX_API_KEY": "vf_your_key_here"
      }
    }
  }
}

Claude Desktop (claude_desktop_config.json) — same config above.

Cursor / Windsurf — go to Settings → MCP Servers and paste the same JSON.

3. Start using it

Ask your AI assistant:

"List open VibeFix bounties for deployment bugs" "Show me the full details for job j57..." "Submit my fix for job j57... — here's what I changed: ..."
