ThreadMine MCP Server

ThreadMine is a Java thread dump analyzer with AI — detects deadlocks, CPU spikes, pool exhaustion and virtual thread pinning. Free online, no signup.

Official MCP server for ThreadMine. Paste a JVM thread dump into your AI assistant — Claude Code, Claude Desktop or Cursor — and get back the detected problems, a health score and a link to the full interactive report, without leaving the chat.

Tools

Tool	What it does	Quota
analyze_thread_dump	Uploads a thread dump (inline text or file path) and returns detected problems, health score (0-100) and the report link	Consumes 1 analysis from your daily quota
get_analysis	Fetches a previous analysis by id	Free (read-only)

Setup

1. Create a free account at threadmine.dev.
2. Create an API key: Settings → API Keys in the web app.
3. Add the server to your assistant:

Claude Code

claude mcp add threadmine -e THREADMINE_API_KEY=tf_live_xxx -- npx -y @threadmine/mcp

Claude Desktop / Cursor (claude_desktop_config.json / .cursor/mcp.json)

{
  "mcpServers": {
    "threadmine": {
      "command": "npx",
      "args": ["-y", "@threadmine/mcp"],
      "env": { "THREADMINE_API_KEY": "tf_live_xxx" }
    }
  }
}

Usage

Ask your assistant things like:

• "Analyze this thread dump: <paste>"
• "Run the dump at /tmp/threaddump.txt through ThreadMine"
• "What did analysis <id> find? Any deadlocks?"

Notes

• Analyses run in the workspace the API key belongs to and count against that workspace's plan quota (the Free plan includes a daily quota — pricing).
• THREADMINE_API_URL can override the API endpoint (self-hosted / staging).
• Requires Node.js ≥ 20.
