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. How we score → Why this is hard to score →
Supply Chain Security0
- No malware scan is available for this kind of package: the supply-chain vendors we use do not cover it. This is a permanent gap in our coverage, not a finding about the package.Unverified
- Known CVEs could not be checked: we found no dependency list to check in this bundle: either it runs a compiled binary, whose bundled manifests we do not read, or none of the package.json, requirements.txt, pyproject.toml or uv.lock files it ships for its runtime declares a dependency we can read (a requirements.txt that only points at a setup.py project, a local path, or a nested requirements file we cannot follow counts as none).Unverified
- Install-script risk not yet assessed.Unverified
- Dependency health could not be checked: we found no dependency list to check in this bundle: either it runs a compiled binary, whose bundled manifests we do not read, or none of the package.json, requirements.txt, pyproject.toml or uv.lock files it ships for its runtime declares a dependency we can read (a requirements.txt that only points at a setup.py project, a local path, or a nested requirements file we cannot follow counts as none).Unverified
Provenance & Transparency45
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Provenance check failed: no build-provenance attestation is published. See how to fix → View diagnostics → Fail
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 5 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability81
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 619 tokens (~123/item across 5 items; 4 tools + 1 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management0
- Stability not yet verified: not enough scan history yet (needs a 30-day window).Unverified
Tool Coverage88
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 64% of tool parameters carry a description.Partial
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 4 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
Unverified: 2 categories
Categories scored 0 because we could not verify them: 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.

Provenance No attestation
The registry publishes no build provenance for this version, so there is nothing to verify.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
audit_html_snippet Audit HTML for WCAG 2.2 defects ~148
Run 18 static WCAG 2.2 checks against an HTML snippet or full page and return findings with the failing success criterion, the offending markup, and a corrected example. Covers alt text, accessible names for links and buttons, form labels, language, title, heading order, duplicate ids, tabindex, aria-hidden, list structure, iframe titles, table headers, video captions, viewport zoom, and autocomplete purpose. Static analysis only: it cannot judge contrast, keyboard traps, focus visibility, or reading order in a rendered page.
| Name | Type | Req | Description |
|---|---|---|---|
| html | string | yes | HTML fragment or full document to audit |
| severity_floor | string | – | Return only errors (default) or every finding |
No output schema declared.

check_ada_compliance_deadlines Check ADA / Section 504 web accessibility deadlines ~159
Return the dated web accessibility obligations that apply to an entity type, from the 1990 ADA statute through the 2027 and 2028 deadlines in the DOJ Title II final rule and the HHS Section 504 rule. Reports what is binding now, what is upcoming within the horizon with days remaining, and the primary source URL for every date. Entity types: title_ii_large, title_ii_small, title_iii_business, federal_contractor, hhs_recipient, eu_business, ontario.

get_verified_fix_example Get a browser-verified WCAG fix example ~155
Return a failing HTML snippet and its corrected version for a WCAG 2.2 defect, with an explanation of the impact on assistive technology and a manual test step. Every pair was executed in headless Chromium against axe-core 4.14.0, and the detection method is reported so you know whether automation catches this defect or a human must. Look up by criterion number (2.4.7), pair id (wcag-1-4-3-01), or keyword (focus indicator).

How do I install the WCAG 2.2 Compliance MCP server?
WCAG 2.2 Compliance ships as an MCPB bundle, a single file you download and open in an MCP host that supports MCPB bundles, such as Claude Desktop. The host reads the launch command from the bundle's own manifest, so there is no command to copy. Before opening it, check the file's SHA-256 matches the one the MCP registry declares for it, a8f5e1694a966ea4bfdf311b1186c7a8d1e243f0e4747de223e95a36e05bc681; the commands to do that are on this page. If it does not match, do not open it.
