# Security Headers Audit (`conserving_mastodon/security-headers-audit`) Actor

One GET, a graded A-F verdict on the security headers browsers enforce: HSTS, CSP (unsafe-inline detection), X-Content-Type-Options, frame protection, Referrer-Policy, cookie flags, HTTPS, version disclosure. Each failure gets a concrete fix. Charged only on completed audits.

## What's an Apify Actor?

Actors are web data automations that power AI and operations. They run on the Apify platform to scrape websites, process data, connect APIs, and automate workflows.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.
Actors are written with capital "A".

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.
The best way to integrate Actors is as follows.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

# README

## Security Headers Audit

**A graded security-header verdict for any URL, in one call.** The checks a security reviewer runs first, productized: HSTS (with max-age strength), Content-Security-Policy (including unsafe-inline/unsafe-eval detection), X-Content-Type-Options, frame protection (XFO or CSP frame-ancestors), Referrer-Policy, Permissions-Policy, HTTPS enforcement, cookie flags (Secure/HttpOnly/SameSite), and version disclosure in Server/X-Powered-By.

### Output

A graded summary:

```json
{ "site": "https://example.com", "grade": "C", "score": 71,
  "fixes": ["Add a Content-Security-Policy; even a report-only policy beats none.", "..."] }
```

Plus one row per check with the observed value, so the fix list is verifiable, not asserted.

### Use cases

- **Agencies and MSPs**: the security line item for every site review, with evidence.
- **Agents doing vendor or acquisition due diligence**: grade a target's basic hygiene in seconds.
- **Dev teams**: run after every deploy; alert if the grade drops.

### Honesty notes

- One polite GET to the URL (redirects followed and reported); nothing else is touched.
- This audits response headers — it is a hygiene check, not a penetration test, and the README will never pretend otherwise.
- Unreachable URLs report cleanly and **you are not charged**; billing is per completed audit.

# Actor input Schema

## `url` (type: `string`):

The URL to audit (e.g. https://example.com). Redirects are followed; the final URL is graded.

## Actor input object example

```json
{
  "url": "https://example.com"
}
```

# Actor output Schema

## `results` (type: `string`):

First row: grade A-F, score, fix list. Then one row per header check with presence, pass/fail, and the observed value.

# API

You can run this Actor programmatically using our API. Below are code examples in JavaScript, Python, and CLI, as well as the OpenAPI specification and MCP server setup.

## JavaScript example

```javascript
import { ApifyClient } from 'apify-client';

// Initialize the ApifyClient with your Apify API token
// Replace the '<YOUR_API_TOKEN>' with your token
const client = new ApifyClient({
    token: '<YOUR_API_TOKEN>',
});

// Prepare Actor input
const input = {
    "url": "https://example.com"
};

// Run the Actor and wait for it to finish
const run = await client.actor("conserving_mastodon/security-headers-audit").call(input);

// Fetch and print Actor results from the run's dataset (if any)
console.log('Results from dataset');
console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`);
const { items } = await client.dataset(run.defaultDatasetId).listItems();
items.forEach((item) => {
    console.dir(item);
});

## Python example

```python
from apify_client import ApifyClient

# Initialize the ApifyClient with your Apify API token
# Replace '<YOUR_API_TOKEN>' with your token.
client = ApifyClient("<YOUR_API_TOKEN>")

# Prepare the Actor input
run_input = { "url": "https://example.com" }

# Run the Actor and wait for it to finish
run = client.actor("conserving_mastodon/security-headers-audit").call(run_input=run_input)

# Fetch and print Actor results from the run's dataset (if there are any)
print(f"💾 Check your data here: https://console.apify.com/storage/datasets/{run.default_dataset_id}")
for item in client.dataset(run.default_dataset_id).iterate_items():
    print(item)

## CLI example

```bash
echo '{
  "url": "https://example.com"
}' |
apify call conserving_mastodon/security-headers-audit --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,conserving_mastodon/security-headers-audit"
        }
    }
}

```

The hosted server signs you in with OAuth on first connect, so no API token belongs in this config. Clients without OAuth support can send an `Authorization: Bearer <APIFY_API_TOKEN>` header instead, using a token from API & Integrations in Apify Console (https://console.apify.com/settings/integrations).
