Compatibility dates

The Zuplo MCP Gateway requires compatibilityDate >= 2026-03-01 in zuplo.jsonc.

JSONCode
// zuplo.jsonc
{
  "version": 1,
  "compatibilityDate": "2026-03-01",
}

The build fails if your project uses any MCP Gateway feature (the McpProxyHandler handler or an mcp-*-inbound policy) with a compatibility date older than 2026-03-01. Bump the date in zuplo.jsonc before adding those features.

New Zuplo projects default to a recent compatibility date, so this only applies to existing projects being upgraded to use the MCP Gateway.

For background on Zuplo's compatibility-date system in general, see Compatibility dates.
