Which MCP Server Should You Choose?
Choose Wcagc MCP when:
You need dedicated capabilities in the Biology & Bioinformatics domain.
You prefer local stdio subprocess transport architecture.
Your security boundary fits: API Key required (Freemium).
Deterministic axe-core accessibility scanning (WCAG 2.1 AA, EN 301 549, PDF/UA) through a wcagc account: scan any public URL or PDF, crawl a whole registered site, replay saved multi-step journeys, and read violation trends. Returns structured findings — rule, severity counts and the success criteria involved — so the assistant reasons over real results rather than guessing from markup. Every scan result carries an automated-coverage disclaimer instead of a score or a pass/fail verdict. Hosted at https://mcp.wcagc.com/mcp, or run it locally with npx -y @wcagc/mcp.
Evidence-based supplement guidance: clinical doses, form comparisons, interactions, cost-per-dose.
