MCP Server as Sales Team

Build and publish MCP servers that plug your SaaS or data product into AI assistants like Claude and ChatGPT, turning every AI query into a zero-CAC sales channel.

01 THE IDEA

The idea is to build an MCP (Model Context Protocol) server that exposes your product's core value — data, actions, or answers — directly inside AI assistants. When a user asks Claude or ChatGPT a relevant question, your MCP server is discovered and your product delivers the answer, acquiring a user with zero ad spend.

This is compared to building for mobile in 2010 — a nascent distribution channel with low competition and high upside. The tactical steps are: identify the question your product answers, vibe-code an MCP server in under 24 hours, publish to registries like Smithery and MCPT, and let AI assistants sell for you 24/7. Real examples cited include 150+ installs in 30 days with $0 ad spend in fintech.

03 THE VERDICT

This is a genuine first-mover opportunity — the MCP registry ecosystem is wide open and the CAC-zero distribution angle is compelling. Anyone with an existing SaaS should build this as a side channel this week. Building a standalone MCP server business (without an underlying product) is riskier but the infrastructure layer (registries, discovery tools) is also a strong bet.
