Building an Agent-Native Cold Outreach Platform: MCP, A2A, and Pay-Per-Inbox Billing

Building an Agent-Native Cold Outreach Platform: MCP, A2A, and Pay-Per-Inbox Billing

Short summary

LDM is an agent-native cold email platform built API-first, shipping an MCP server for Claude Desktop integration and A2A protocol discovery for agent-to-agent delegation—firsts in the cold outreach category. It bills only on verified inbox delivery using seed cohort methodology, eliminating the 40% spam-folder waste traditional pay-per-send models accept. Launching Product Hunt this weekend with NestJS backend and hybrid OpenAI/Anthropic integration.

  • •MCP server for Claude Desktop: typed tool access instead of API webhooks
  • •A2A agent-card protocol: agents can discover and delegate to LDM without pre-configuration
  • •Pay-per-verified-inbox billing: eliminates 40% spam-folder waste of traditional per-send models

Generated with AI, which can make mistakes.
