Nexus Leads AI — MCP Bridge V1

Servidor MCP remoto e privado para conectar o Nexus Leads AI a clientes compatíveis com Model Context Protocol.

Arquitetura

ChatGPT / MCP Inspector
        ↓ OAuth 2.1
GitHub OAuth + lista de usuários permitidos
        ↓
Cloudflare Worker: nexus-leads-mcp
        ↓
D1 nexus-leads-db + API do Nexus principal

O MCP fica em um Worker separado para evitar que uma falha no conector derrube o site principal.
