Claude Tools API ready · Claude Desktop via MCP

Connect Claude to OrderCore.

Three steps

Get from API key to first checkout session

1. Get your API key

Use an OrderCore API key with write scope and decide which API base URL Claude should hit.

terminal

export ORDERCORE_BASE_URL="https://api.ordercore.ai"
export ORDERCORE_API_KEY="oc_live_..."

2. Build the local MCP server

Compile the standalone OrderCore MCP wrapper once. Claude Desktop will start this binary over stdio.

terminal

go build -o ./bin/ordercore-mcp ./cmd/ordercore-mcp

3. Ask Claude to create the first session

After Claude Desktop reloads, ask for a checkout session with a specific SKU and quantity.

terminal

Create a checkout session for sku 3f4f8d41...
quantity 1, currency USD.
