## 🎯 What you get

Stop wrestling with Java paths, broken plugins, and hand-written extractors.

Point Cursor / Claude at this MCP server and ask for a performance test. It will:

1. **Heal** Java + Apache JMeter **5.6.3** + plugins under `~/.perfsage` (Docker fallback if needed)
2. **Import** HAR / OpenAPI / Postman traffic
3. **Auto-correlate** tokens, cookies, and IDs into JMeter variables
4. **Discover** the throughput knee when you don’t know the workload
5. **Report** a PASS / WARN / FAIL led by **p95 + p99** (never averages alone)

> Analysis, not dashboards. Every run ends in a decision.

## ⚡ 60-second setup

Requires **Python 3.10+**. Prefer [uv](https://docs.astral.sh/uv/) (macOS system `python3` is often 3.9; uv-managed Pythons also block bare `pip` via PEP 668).

```bash
# try it (no install)
uvx perfsage-jmeter-mcp --version
uvx perfsage-jmeter-mcp
```

```bash
# install as a user tool (recommended)
uv tool install perfsage-jmeter-mcp
perfsage-jmeter-mcp --version
```

```bash
# or inside a project venv
uv venv --python 3.12
source .venv/bin/activate   # Windows: .venv\Scripts\activate
uv pip install perfsage-jmeter-mcp
```

> **Do not** run `python3.12 -m pip install …` against a uv-managed interpreter — you’ll get `externally-managed-en…
