Connect Codex, Claude, or another MCP host to the v3 preview.
The v3 quickstart has copyable configurations for
Codex, Claude Code, Claude Desktop, and other streamable HTTP clients.Use the single account-resolved endpoint:
https://api.interchange.io/mcp/v3
Keep the v3 connector separate from an existing v2 Buyer or Seller connector
while evaluating the preview. Selecting v3 in these docs does not change a
client configuration or enroll an account.The server can close a connection after 30 minutes or during a deploy. Reuse
the existing MCP session when reconnecting. Do not design long-running work
around one open tool call; its result is lost if that call is interrupted
before completion.
