## Get Started

```bash
pip install mcp-sentinel
mcpsentinel "python my_server.py"
```

That's it. No config file. No test code to write. MCPSentinel connects to your server, discovers every tool, generates hundreds of test cases, and prints the results:

```
MCPSentinel v0.1.0

  Server:     python my_server.py
  Transport:  stdio (auto-detected)
  Modes:      schema, fuzz
  Output:     terminal

Discovering tools...  3 tools found

Running 47 tests ━━━━━━━━━━━━━━━━━━━━━━ 100%

Results: 44 passed, 3 failed, 0 errors
```

---

## What It Tests

MCPSentinel runs two test modes by default:

**Schema validation** — sends valid inputs, omits required fields one at a time, tests enum boundaries, type mismatches.

**Adversarial fuzzing** — SQL injection, XSS, path traversal, command injection, null bytes, format strings, oversized payloads, unicode stress tests. Every fuzz test expects the server to not crash — returning an error is fine.

## Common Usage

```bash
# Test your server (zero config)
mcpsentinel "python my_server.py"

# Schema tests only
mcpsentinel "python server.py" -m schema

# HTML report
mcpsentinel "python server.py" -f html

# SSE server (transport auto-detected from URL)
mcpsentinel "http://localhost:8001/sse"

# Streamable HTTP
mcpsentinel "http://localhost:8001/mcp"

# Test specific tools
mcpsentinel "python server.py" --tools "search_*"

# Exclude …
