Feature & Specification Comparison

Specification	Context Firewall Alepha188838884 Aggregators	Mcp Gateway ViperJuice Aggregators
Summary	Local proxy that collapses N downstream MCP servers into 4 meta-tools with progressive tool discovery (measured: 122 tools → 4, 28.6K tokens of definitions saved), compresses large tool outputs (HTML→Markdown, JSON structure summarization, base64 stripping — 60–95% measured on real pages/APIs) with full-output retrieval via readmore, and prints a per-session token-savings report. Security-relevant outputs are never silently compressed. Install: npx -y context-firewall --config config.json	A meta-server for minimal Claude Code tool bloat with progressive disclosure and dynamic server provisioning. Exposes 9 stable meta-tools, auto-starts Playwright and Context7, and can dynamically provision 25+ MCP servers on-demand from a curated manifest.
