MCP Registry Submission & Optimization

Context: Building tools isn't enough - they must be discoverable. This task ensures all 5 MCP tools are properly submitted to the official registry, have optimized descriptions, and appear in relevant searches. This is the "publishing" step that makes everything else work.

Deliverables:

1. All 5 tools submitted to modelcontextprotocol.io registry
2. Optimized titles and descriptions for search:
   • Include keywords: "earn money", "blockchain", "gas fees", "freelance"
   • Clear one-line value props
3. Cross-linking between tools (each tool's README mentions the others)
4. Verification that tools appear in Claude's MCP discovery
5. GitHub organization with consistent branding
6. PUBLISHED TO:
   • MCP registry (all 5 tools verified live)
   • Hacker News "Show HN" post about the toolkit
   • Reddit r/ClaudeAI post introducing tools

Success Metric: All 5 tools discoverable in MCP ecosystem
