## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-10-16.

- **Supply Chain Security**: 100/100
  - No malware found by supply-chain analysis.
  - No known CVEs affecting this package version or its production dependencies.
  - No install/post-install scripts declared.
  - 0 of 3 dependencies flagged as unhealthy.
- **Provenance & Transparency**: 45/100
  - Source repository is publicly reachable at the declared URL.
  - Provenance check failed: no build-provenance attestation is published.
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 5 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 73/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 701 tokens (~140/item across 5 items; 5 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 5 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

**Unverified: 1 category.** A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

First indexed and scored.

## MCP tools (5)

### `atlas_scrape` (~159 tokens)

Quickly extract clean, readable text, markdown, and links from a web page using Atlas's fast synchronous parser. Strips cookie banners, navigation clutter, and ads. Best for articles, documentation pages, and general web reading.

Input parameters:

- `formats` (array): Content formats to include in the response. 'markdown' returns clean formatted content; 'links' includes discovered hyperlinks; 'text' returns raw stripped text.
- `max_output_chars` (integer): Maximum character budget for the returned content. If content exceeds this limit, it is cleanly truncated at paragraph boundaries with truncation notice.
- `timeout_ms` (integer): Fetch and processing timeout in milliseconds.
- `url` (string, required): The absolute HTTP or HTTPS URL of the web page to scrape.

Output parameters:

- `links` (array)
- `markdown` (string)
- `resource_uri` (string)
- `stats` (object)
- `text` (string)
- `title` (string)
- `truncated` (boolean)
- `url` (string)

### `atlas_compile` (~173 tokens)

Compile a public web page into clean, deterministic, LLM-optimized markdown or structured AST nodes using the full 12-pass Atlas compiler. Strips boilerplate and generates section hierarchies. Best for complex documentation, API references, and dense technical articles.

Input parameters:

- `force_fresh` (boolean): Bypass edge cache and force a fresh compilation from origin.
- `format` (string): 'markdown' returns clean LLM-ready markdown; 'semantic' returns the structured AST section graph; 'markdown+links' appends discovered navigation links.
- `max_output_chars` (integer): Maximum character budget for the returned content. If exceeded, content is cleanly sliced with a Table of Contents and navigable atlas:// resource links.
- `url` (string, required): The absolute HTTP or HTTPS URL of the web page to compile.

Output parameters:

- `ast` (object)
- `compilation_id` (string)
- `headings` (array)
- `markdown` (string)
- `resources` (object)
- `stats` (object)
- `title` (string)
- `truncated` (boolean)
- `url` (string)

### `atlas_map` (~138 tokens)

Discover the URL topology, sitemap structure, and hierarchy of a website without compiling individual pages. Use before crawling to identify relevant documentation paths and section boundaries.

Input parameters:

- `include_subdomains` (boolean): Whether to discover links on subdomains of the target host.
- `limit` (integer): Maximum number of discovered links to return.
- `sitemap` (string): Strategy for inspecting sitemap.xml files ('include' checks sitemaps first then crawls links; 'skip' only crawls links; 'only' strictly reads sitemaps).
- `url` (string, required): Root URL or domain to map (e.g. 'https://docs.stripe.com').

Output parameters:

- `count` (number)
- `duration_ms` (number)
- `root_url` (string)
- `sitemaps_found` (array)
- `urls` (array)

### `atlas_batch_compile` (~86 tokens)

Compile a bounded list of explicit URLs in parallel. Returns clean markdown for each page within a consolidated budget. Maximum 20 URLs per batch call.

Input parameters:

- `format` (string): Content format for compilation.
- `max_output_chars_per_page` (integer): Character limit allocated per individual page.
- `urls` (array, required): List of URLs to compile in parallel (maximum 20 per call).

Output parameters:

- `failed` (number)
- `results` (array)
- `successful` (number)
- `total_requested` (number)

### `atlas_crawl` (~145 tokens)

Traverse and compile a bounded subsection of a website (such as an API reference or documentation folder) starting from a seed URL. Returns consolidated page summaries and navigable resource URIs.

Input parameters:

- `exclude_paths` (array): Path glob patterns to exclude from compilation (e.g. ['/changelog/**', '/**/pricing']).
- `include_paths` (array): Path glob patterns to restrict compilation (e.g. ['/docs/api/**', '/reference/**']).
- `max_depth` (integer): Maximum link hop depth from seed URL.
- `max_pages` (integer): Maximum number of pages to discover and compile.
- `url` (string, required): Starting seed URL for the crawl.

Output parameters:

- `crawl_id` (string): Atlas job identifier for tracking crawl status and reading results via atlas://crawls/{id}.
- `duration_ms` (number)
- `pages` (array)
- `pages_crawled` (number)
- `pages_failed` (number)
- `root_url` (string)
- `summary_markdown` (string): Structured Table of Contents and synopsis of crawled pages within context budget.

Atlas Web Compiler & Scraper scores 70 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 16 October 2026. It declares no install or post-install scripts. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Atlas Web Compiler & Scraper MCP server expose?

Atlas Web Compiler & Scraper exposes 5 tools: atlas_scrape, atlas_compile, atlas_map, atlas_batch_compile, atlas_crawl. Their descriptions and schemas cost roughly 701 tokens of context every time the server is loaded.

### Is the Atlas Web Compiler & Scraper MCP server still maintained?

Atlas Web Compiler & Scraper is still listed as active in the MCP registry. We last reached this channel on 16 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the Atlas Web Compiler & Scraper MCP server under?

Atlas Web Compiler & Scraper declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
