Feature & Specification Comparison

Specification	Cinderwright API cinderwright-ai Aggregators	Context Firewall Alepha188838884 Aggregators
Summary	x402 Discovery Hub. Search engine for the agent economy with 1450+ services indexed. Pay with USDC on Base via x402.	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
