wcagc-mcp
WCAG-Compliance/wcagc-mcp lets an assistant run real axe-core accessibility scans through the user's own wcagc account, rather than guessing accessibility from markup it can see. Tools cover a single URL or PDF, a full-site crawl, saved multi-step journeys, and violation trends.
Emerging. No concerning findings. Grades remain capped until the project builds reputation through adoption. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
12/12 tools missing one or more hints — check_pdf (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_pdf_check (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); list_sites (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +9 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Tool inputs are validated
11/12 tool handlers declare input schemas (92%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Dev dependencies
6 critical/high in dev-only deps (does not ship to users)
Upgrade dev dependencies when convenient.
Domain consistency
npm scope @wcagc doesn't match GitHub owner wcag-compliance
Use the same org name across GitHub, npm, and your homepage so users can verify the publisher.
