README
Product Catalog MCP
An Excel-backed MCP server plus a JOUST product management app.
Local MCP server
npm install
npm run init-data
npm start
The catalog is stored in data\products.xlsx. The MCP server exposes:
list_productssearch_productsadd_productupdate_productdelete_product
VS Code configuration is included in .vscode\mcp.json, and the custom agent is in
.github\agents\product-catalog.agent.md. The agent embeds the MCP server
configuration for GitHub Copilot cloud agent. Its setup workflow installs Node.js
dependencies before the agent starts.
Set PRODUCT_CATALOG_FILE to use a different workbook.
For an HTTP MCP endpoint:
npm run start:http
The local endpoint is http://localhost:3000/mcp. Deploy this Node.js process to a
server-capable host to obtain a public MCP URL; JOUST itself hosts only static apps.
JOUST app
The static app in web\ stores its shared data in JOUST and supports product CRUD,
search, and Excel import/export. The hosted JOUST database and local Excel workbook
are separate stores.
