ChatGPT Plugin / GPT Store

ChatGPT has over 100 million weekly active users who use it to discover products and services. A custom GPT in the GPT Store surfaces Gera services when users ask relevant questions — "find me a plumber in Yerevan", "what compliance tool do I need for the EU AI Act".

How it works

A custom GPT is configured with a system prompt describing the product, a retrieval action that calls the product's MCP server or REST API, and a GPT Store listing optimised for search within the platform. When a user's query matches the GPT's description, ChatGPT surfaces it as a recommended tool.

What we measure

  • GPT opens per week
  • Handoff clicks to product
  • Signups attributed to GPT referral

Claude MCP Integration

Anthropic's Model Context Protocol (MCP) allows Claude to call external tools and data sources during conversations. A published MCP server for each Gera product means Claude can book a GeraHome tradesperson, check GeraCompliance requirements, or post a GeraJobs listing directly within a Claude conversation — without the user leaving the chat interface.

How it works

Each product exposes an MCP server (published to npm as @gera/[product]-mcp) with typed tool definitions. Claude desktop users install the server; enterprise users configure it in their Claude for Work deployment. MCP catalogue listings (mcp.so, Glama, Smithery) drive organic discovery.

What we measure

  • MCP server installs
  • Tool call volume per product
  • Signups attributed to MCP session
