How to Embed Your App in AI Clients with MCP: Complete Guide for Product Leaders

Professional software usage is shifting toward AI clients like Claude and ChatGPT. The Model Context Protocol (MCP), a JSON-RPC 2.0 protocol, enables apps to embed via tools and prompts. Implementation involves selecting clients, defining embedding depth, and using OAuth 2.1 + PKCE. Costs range from $100K for read-only apps to $700K for action-based ones. Product teams should evaluate buyer workflows by 2026, choosing between aggressive multi-client shipping, strategic single-client focus, defensive read-only options, or maintaining traditional destinations.
