Feature & Specification Comparison

Specification	S Seshat MCP Biology & Bioinformatics	Wcagc MCP WCAG-Compliance Biology & Bioinformatics
Summary	Structural code intelligence for AI agents: real call graphs, blast radius, and change history.	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.
