MCP protocol versions.

The Model Context Protocol uses string-based version identifiers following the format YYYY-MM-DD, to indicate the last date backwards incompatible changes were made. Versions are available at https://github.com/modelcontextprotocol/modelcontextprotocol/releases

Example

// Create a KMS key for encryption
const encryptionKey = new kms.Key(this, "GatewayEncryptionKey", {
  enableKeyRotation: true,
  description: "KMS key for gateway encryption",
});

// Create gateway with KMS encryption
const gateway = new agentcore.Gateway(this, "MyGateway", {
  gatewayName: "my-encrypted-gateway",
  description: "Gateway with KMS encryption",
  protocolConfiguration: new agentcore.McpProtocolConfiguration({
    instructions: "Use this gateway to connect to external MCP tools",
    searchType: agentcore.McpGatewaySearchType.SEMANTIC,
    supportedVersions: [agentcore.MCPProtocolVersion.MCP_2025_03_26],
  }),
  authorizerConfiguration: agentcore.GatewayAuthorizer.usingCustomJwt({
    discoveryUrl: "https://auth.example.com/.well-known/openid-configuration",
    allowedAudience: ["my-app"],
    allowedClients: ["my-client-id"],
    allowedScopes: ["read", "write"],
  }),
  kmsKey: encryptionKey,
  exceptionLevel: agentcore.GatewayExceptionLevel.DEBUG,
