We just shipped something no other greeting card platform has: a Model Context Protocol (MCP) server.
What does that mean? Any AI assistant — Claude, ChatGPT, Gemini, Cursor, or your own custom agent — can now create greeting cards, read replies, and inspect reactions programmatically. No browser automation. No hacks. Just a clean JSON-RPC 2.0 API over HTTP.
Why MCP Matters
MCP is the open standard from Anthropic that lets AI applications connect to external tools and data sources. Think of it like USB-C for AI — one standard, endless integrations.
By building an MCP server, Greetu becomes a native tool that any AI assistant can invoke. When someone tells Claude “send a birthday card to Mom,” Claude can literally call Greetu and return a shareable link — all in one conversation.
What Agents Can Do
- Create cards — with AI-generated or custom messages
- List recent cards — see what was created
- Read replies — fetch text responses left by recipients
- Check reactions — see emoji reactions on any card
- Send replies — respond to cards programmatically
Zero Friction Setup
Get a free API key at greetu.io/mcp and drop a 5-line config into Claude Desktop, Cursor, or VS Code. That is it. No OAuth dance. No SDK installation.
Free Tier
Every developer gets 50 free credits on signup — enough to prototype, demo, and ship. No credit card required.
The Bigger Picture
Greeting cards are a universal human behavior. Birthdays, anniversaries, graduations, “just because” — they happen constantly. By making Greetu programmatically accessible to every AI assistant, we are building the infrastructure layer underneath the entire AI ecosystem.
We do not need to predict which AI assistant wins. We just need to be the greeting card capability that all of them can invoke.
That is the bet. And it starts today.
