## Description
Benchmark, memory, Big O analysis for AI agents

## Claude Desktop Quick Installation
Remote MCP endpoint (confidence: high). Install path detected from listing signals. Add as a URL/SSE server in your client:

```json
"mcpServers": {
  "perf": {
    "url": "https://modelcontextprotocol.io/"
  }
}
```

## Documentation & README


# mcp-perf-tools

Performance analysis tools for AI agents, exposed via the [Model Context Protocol (MCP)](https://modelcontextprotocol.io/).

## Tools

### benchmark

Benchmark JavaScript code execution. Run a snippet N times and measure min/max/avg/median/p95/p99 latency and operations per second. Optionally compare two implementations side by side.

**Parameters:**
- `code` (string) — JavaScript code to benchmark
- `iterations` (number, default 1000) — Number of iterations
- `compareCode` (string, optional) — Second implementation to compare
- `labelA` / `labelB` (string) — Labels for comparison output

### memory_analyze

Analyze Node.js memory usage: heap used/total, RSS, external memory, and array buffers. Takes snapshots over time and uses linear regression to detect trends and potential memory leaks.

**Parameters:**
- `action` — `"snapshot"` | `"analyze"` | `"clear"`

### big_o_estimate

Estimate Big O complexity from empirical timing data. Fits measurements against O(1), O(log n), O(n), O(n log n), O(n^2), O(n^3), and O(2^n) using R-squared scoring. Includes an ASCII growth curve visualization.

**Parameters:**
- `inputSizes` (number[]) — Array of input sizes
- `executionTimesMs` (number[]) — Corresponding execution times in ms

### bundle_analyze

Analyze a JavaScript bundle file: raw size, gzip compressed estimate, detected module count, largest modules, and tree-shaking opportunities (side effects, duplicates).

**Parameters:**
- `filePath` (string) — Absolute path to the bundle file

### load_test

Simple HTTP load tester. Sends N requests at a given concurrency level and reports response time percentiles, error rate, throughput (req/sec), and status code distribution.

**Parameters:**
- `url` (string) — Target URL
- `totalRequests` (number, default 100) — Total requests to send
- `concurrency` (number, default 10) — Concurrent request count
- `method` (string, default "GET") — HTTP method
- `headers` (object, optional) — HTTP headers
- `body` (string, optional) — Request body
- `timeoutMs` (number, default 30000) — Request timeout

## Setup

```bash
npm install
npm run build
```

## Usage with Claude Desktop

Add to your `claude_desktop_config.json`:

```json
{
  "mcpServers": {
    "perf-tools": {
      "command": "node",
      "args": ["D:/products/mcp-servers/mcp-perf-tools/dist/index.js"]
    }
  }
}
```
