Feature & Specification Comparison

Specification	Code Impact MCP Biology & Bioinformatics	Wcagc MCP WCAG-Compliance Biology & Bioinformatics
Summary	Dependency graph & blast-radius analysis for TypeScript/JS. Predict breaks before commit.	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.

Tools & Capabilities Breakdown

Code Impact MCP Tools (5)

gate_check

Pre-commit safety gate. Analyzes specified changes and returns a **PASS/WARN/BLOCK verdict** with reasons. Use as a bounded decision aid before committing multi-file changes, including workspace-aware checks in pnpm/package.json workspaces and lerna-style monorepos. BLOCK means risk exceeds thresho…

detect_cycles

Return compact strongly connected components for circular dependencies in the current TS/JS graph. Use before refactors or release gating when you want a short list of cycle hotspots instead of a full graph visualization.

analyze_impact

Analyze the blast radius of changing specific files. Returns which files would be directly and transitively affected, with a risk score (0-1). Use BEFORE committing multi-file changes to understand what might break. Does NOT modify any files.

get_dependencies

Get the import and importedBy relationships for a specific file. Shows what this file depends on and what depends on it. Use to understand coupling before refactoring a file.
