npm package: @surfinguard/core-engine
Description: Heuristic scoring engine for the Surfinguard AI Security SDK — 18 analyzers, 152 threat patterns
Author: Surfinguard
Latest version: 1.0.0

# @surfinguard/core-engine

Heuristic scoring engine for the [Surfinguard](https://surfinguard.com) AI Security SDK. Analyzes AI agent actions against 5 risk primitives with 68 threat patterns — zero network calls, runs entirely in-process.

## Installation

```bash
npm install @surfinguard/core-engine
```

> **Note:** Most users should install `@surfinguard/sdk` instead, which provides a higher-level `Guard` class.

## Analyzers

| Analyzer | Threats | Patterns |
|----------|---------|----------|
| `UrlAnalyzer` | U01-U14 | Data URIs, IP addresses, brand impersonation, shorteners, risky TLDs, cloud metadata, free hosting |
| `CommandAnalyzer` | C01-C20 | Destructive ops, exfiltration, reverse shells, pipe-to-shell, privilege escalation, persistence, fork bombs, container escape |
| `TextAnalyzer` | P01-P12 | Prompt injection, goal hijacking, tool manipulation, persona hijacking, encoding evasion, markup injection |
| `FileReadAnalyzer` | FR01-FR10 | SSH keys, system credentials, cloud credentials, environment files, browser data |
| `FileWriteAnalyzer` | FW01-FW12 | System config overwrite, SSH authorized_keys injection, startup persistence, git hook injection |

## Usage

```typescript
import { CoreEngine } from '@surfinguard/core-engine';

const engine = new CoreEngine();

const result = engine.check('url', 'https://paypa1.com/login');
// { score: 9, level: 'DANGER', primitive: 'MANIPULATION', reasons: ['Brand impersonation: paypal'], ... }

const cmd = engine.check('command', 'rm -rf /');
// { score: 10, level: 'DANGER', primitive: 'DESTRUCTION', ... }
```

## Scoring Model

- **Within each primitive**: Scores are additive (sum), capped at 10
- **Composite score**: `max(primitive_scores)`
- **Risk levels**: SAFE (0-2), CAUTION (3-6), DANGER (7+)

## Risk Primitives

| Primitive | Description |
|-----------|-------------|
| DESTRUCTION | Data loss, system damage |
| EXFILTRATION | Data theft, credential access |
| ESCALATION | Privilege escalation |
| PERSISTENCE | Backdoor installation, startup modification |
| MANIPULATION | Phishing, prompt injection, deception |

## Pattern Databases

Versioned JSON files in `patterns/`:
- `urls.json` — URL threat patterns
- `brands.json` — Brand impersonation patterns
- `commands.json` — Command threat patterns
- `text.json` — Prompt injection patterns
- `file-read.json` — Sensitive file read patterns
- `file-write.json` — Sensitive file write patterns

## Usage

```ts
import { initialize, CoreEngine } from '@surfinguard/core-engine-wasm';

// Must initialize WASM before first use
await initialize();

const engine = new CoreEngine();
const result = engine.check({ type: 'url', value: 'https://example.com' });

console.log(result.level);  // 'SAFE' | 'CAUTION' | 'DANGER'
console.log(result.score);  // 0-10
```

## Supported Action Types

`url`, `command`, `text`, `file_read`, `file_write`, `api_call`, `query`, `code`, `message`, `transaction`, `auth`, `git`, `ui_action`, `infra`, `agent_comm`, `data_pipeline`, `document`, `iot`

## Risk Primitives

Each action is scored against 5 risk primitives: **DESTRUCTION**, **EXFILTRATION**, **ESCALATION**, **PERSISTENCE**, **MANIPULATION**. The composite score is `max(primitive_scores)`.

Run directly with npx (no install needed):

```bash
npx @surfinguard/mcp-server
```

Or install globally:

```bash
npm install -g @surfinguard/mcp-server
```

## Configuration

### Claude Code

Add to your Claude Code MCP config:

```json
{
  "mcpServers": {
    "surfinguard": {
      "command": "npx",
      "args": ["@surfinguard/mcp-server"]
    }
  }
}
```

### Cursor / VS Code

Add to your MCP settings:

```json
{
  "surfinguard": {
    "command": "npx",
    "args": ["@surfinguard/mcp-server"]
  }
}
```

## Available Tools

The server exposes 19 tools for checking AI agent actions:

| Tool | Description |
|------|-------------|
| `check` | Universal security check for any action type |
| `check_url` | URL phishing & impersonation detection (14 threats) |
| `check_command` | Shell command risks — destructive ops, reverse shells (20 threats) |
| `check_text` | Prompt injection detection (12 threats) |
| `check_file_read` | Sensitive file exfiltration detection (10 threats) |
| `check_file_write` | File write threats — config overwrite, persistence (12 threats) |
| `check_api_call` | API security — SSRF, credential forwarding (10 threats) |
| `check_query` | SQL injection & data exfiltration (7 threats) |
| `check_code` | Code analysis — reverse shells, crypto mining (8 threats) |

**Total: 18 analyzers, 152 threat patterns**

## How It Works

The MCP server runs the Surfinguard heuristic engine locally (no network calls). Each action is scored against 5 risk primitives: DESTRUCTION, EXFILTRATION, ESCALATION, PERSISTENCE, MANIPULATION.

Results include a risk level (SAFE / CAUTION / DANGER), composite score (0-10), matched threat IDs, and per-primitive breakdowns.

npm package: @surfjs/web
Description: Framework-agnostic window.surf local execution runtime for Surf-enabled websites
Latest version: 0.5.1

<div align="center">

# @surfjs/web

**The `window.surf` runtime — local command execution for AI agents in the browser.**

[![npm](https://img.shields.io/npm/v/@surfjs/web?color=0057FF&label=npm)](https://www.npmjs.com/package/@surfjs/web)
[![License: MIT](https://img.shields.io/badge/license-MIT-green.svg)](https://github.com/hauselabs/surf/blob/main/LICENSE)

</div>

---

Framework-agnostic runtime that powers `window.surf` — the interface browser-based AI agents use to interact with your website. Zero dependencies.

Commands registered with `@surfjs/web` run **locally in the browser**, modifying UI state directly. No server roundtrip. Instant feedback.

## Install

```bash
npm install @surfjs/web
```

## Usage

```js
import { initSurf, registerCommand } from '@surfjs/web'

// Initialize window.surf (with optional server fallback)
initSurf({ endpoint: 'https://myapp.com' })

// Register a local command handler
registerCommand('canvas.addCircle', {
  mode: 'local',  // browser-only, no server call
  run: (params) => {
    addCircleToCanvas(params)
    return { ok: true }
  }
})

// Now agents (or devtools) can run:
// await window.surf.execute('canvas.addCircle', { x: 200, radius: 50 })
```

## Modes

| Mode | Behavior |
|------|----------|
| `'local'` | Runs only in browser. No server call. |
| `'sync'` | Runs in browser, then POSTs to server in background for persistence. |

If no local handler is registered, `window.surf.execute()` falls back to the server endpoint.

## Framework Wrappers

`@surfjs/web` is the engine. Framework packages are thin wrappers:

- **React:** `@surfjs/react` — `useSurfCommands()` hook
- **Vue:** `@surfjs/vue` — `useSurfCommands()` composable
- **Svelte:** `@surfjs/svelte` — `surfCommands()` function

## API

| Function | Description |
|----------|-------------|
| `initSurf(options?)` | Install `window.surf` with optional HTTP endpoint |
| `registerCommand(name, config)` | Register local handler, returns cleanup fn |
| `unregisterCommand(name)` | Remove handler by name |
| `getSurf()` | Get current `window.surf` instance |
| `destroySurf()` | Tear down everything |

npm package: @surflog/geospeed
Description: GeoJSON speed
Latest version: 1.2.10

# GeoJSON speed measure

This is build for [surflog.app](https://surflog.app/).

Given GeoJSON it will measure:

- topspeed: Fastest speed
- topspeed250: Fastest speed over 250 meter
- topspeed500: Fastest speed over 500 meter

ToDo:

- legs: Number of rides forth and back
- planing: Time planing in % (> 18 km/h)

For each position, a `timestamp` property is expected in order to calculate speed between each position.
