Overview

Description from the maker (original English)

Analyze JVM thread dumps with ThreadMine: deadlocks, CPU spikes, pool exhaustion, health score.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs on your computer
  • Transport: stdio
  • Category: Clinics & health
  • You need to fill in: THREADMINE_API_KEY

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on your computer with your user’s permissions (files, network, apps).
  • You fill in yourself: THREADMINE_API_KEY, THREADMINE_API_URL

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

  • npmNode.js installed (for the npx command)

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

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

Run this in your terminal

claude mcp add threadmine --env THREADMINE_API_KEY=your-value --env THREADMINE_API_URL=your-value -- npx -y @threadmine/mcp

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

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

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "threadmine": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@threadmine/mcp"
      ],
      "env": {
        "THREADMINE_API_KEY": "your-value",
        "THREADMINE_API_URL": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Your choice stays on this device in a cookie; no account needed.

Values you fill in

  • THREADMINE_API_KEY secret env
    Optional. Without it, analyses run anonymously (5/hour per IP, report expires in 7 days)
  • THREADMINE_API_URL env
    Override the ThreadMine API endpoint (default: https://api.threadmine.dev)

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Common questions

Is Threadmine MCP safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: THREADMINE_API_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.2.0) reached the registry 8 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

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.

No account needed. Without an API key the server uses the same public endpoint as the threadmine.dev analyzer. With a key, analyses land in your ThreadMine workspace.

Tools

ToolWhat it does
analyze_thread_dumpUploads a thread dump (inline text or file path) and returns detected problems, health score (0-100) and the report link
get_analysisFetches a previous analysis by the id analyze_thread_dump returned. Read-only, consumes nothing

Setup

Claude Code plugin (MCP server plus a skill that tells Claude when to use it)

claude plugin marketplace add maschiojv/threadmine-mcp

claude plugin install threadmine@threadmine-plugins

Claude Code, server only

claude mcp add threadmine -- npx -y @threadmine/mcp

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

{

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

With or without an account

Without an API keyWith THREADMINE_API_KEY
Limit5 analyses per hour, 20 per day, per IPYour plan's quota (pricing)
ReportPublic link (threadmine.dev/resultado/...), anyone with it can open it, expires after 7 daysPrivate, in your workspace

To use your account, create an API key in the web app (Settings → API Keys) and set THREADMINE_API_KEY in the server's environment. For the plugin, export it in the shell that starts Claude Code; for the other setups, add it to the env block ("env": { "THREADMINE_API_KEY": "tf_live_xxx" }) or pass -e THREADMINE_API_KEY=tf_live_xxx to claude mcp add.

Usage

Ask your assistant things like:

  • *"Analyze this thread dump: "*
  • *"Run the dump at /tmp/threaddump.txt through ThreadMine"*
  • *"My Spring Boot app stopped answering, here's the jstack output"*
  • *"What did analysis find? Any deadlocks?"*

Privacy

The dump is sent to the ThreadMine API over TLS. Thread dumps can carry hostnames, class and package names and SQL fragments. If your policy forbids sending production dumps to a third party, run them through tm-anon first: it anonymizes the dump locally, keeps the mapping on your machine, and ThreadMine still analyzes the result.

Hung tests in CI

When a JVM test hangs in GitHub Actions and the job hits timeout-minutes, threadmine-action dumps the stuck test JVM and writes the same diagnosis to the job summary and the pull request. It's one line in the workflow (uses: maschiojv/threadmine-action@v1) and needs no account.

Notes

  • THREADMINE_API_URL overrides the API endpoint (self-hosted / staging). THREADMINE_SITE_URL overrides the site used in anonymous report links.
  • Requires Node.js ≥ 20.
