Turn it off only for a service whose metadata declares properties non-nullable that its POST handler actually rejects or defaults (live TripPin does this with `Gender`). JSON kind, unknown property, enum, and `MaxLength` checks stay on regardless. ### EnumJsonFormat Gets or sets how enumeration values are advertised in JSON Schema and accepted on input. #### Syntax ```csharp theme={null} public Microsoft.OData.Mcp.Core.Catalog.ODataEnumJsonFormat EnumJsonFormat { get; set; } ``` #### Property Value Type: `Microsoft.OData.Mcp.Core.Catalog.ODataEnumJsonFormat` #### Remarks Defaults to [ODataEnumJsonFormat.Auto](https://ai.easyaf.dev/odata-mcp/api-reference/Microsoft/OData/Mcp/Core/Catalog/ODataEnumJsonFormat.md#auto): member names are advertised and JSON numbers are also accepted. The advertised schema never changes during a catalog's lifetime. ### ExcludeEntitySets Gets or sets entity set names to exclude from named tools and resources. #### Syntax ```csharp theme={null} public System.Collections.Generic.List ExcludeEntitySets { get; set; } ``` #### Property Value Type: `System.Collections.Generic.List` ### IncludeActions Gets or sets a value indicating whether named `action_*` tools are generated. #### Syntax ```csharp theme={null} public bool IncludeActions { get; set; } ``` #### Property Value Type: `bool` #### Remarks Defaults to `true`. Turning it off omits named action tools; `odata_call` remains. ### IncludeCreate Gets or sets a value indicating whether create tools are generated. #### Syntax ```csharp theme={null} public bool IncludeCreate { get; set; } ``` #### Property Value Type: `bool` ### IncludeDelete Gets or sets a value indicating whether delete tools are generated. #### Syntax ```csharp theme={null} public bool IncludeDelete { get; set; } ``` #### Property Value Type: `bool` ### IncludeEntitySets Gets or sets entity set names that receive named tools first. #### Syntax ```csharp theme={null} public System.Collections.Generic.List IncludeEntitySets { get; set; } ``` #### Property Value Type: `System.Collections.Generic.List` ### IncludeFunctions Gets or sets a value indicating whether named `function_*` tools are generated. #### Syntax ```csharp theme={null} public bool IncludeFunctions { get; set; } ``` #### Property Value Type: `bool` #### Remarks Defaults to `true`. Turning it off omits named function tools; `odata_call` remains. ### IncludeUpdate Gets or sets a value indicating whether update tools are generated. #### Syntax ```csharp theme={null} public bool IncludeUpdate { get; set; } ``` #### Property Value Type: `bool` ### InstructionsPreface Gets or sets service-specific guidance placed before the default MCP server instructions. #### Syntax ```csharp theme={null} public string InstructionsPreface { get; set; } ``` #### Property Value Type: `string?` #### Remarks The default text in [ODataMcpInstructions.Default](https://ai.easyaf.dev/odata-mcp/api-reference/Microsoft/OData/Mcp/Core/Catalog/ODataMcpInstructions.md#default) is always included; this only prepends. See [String)](https://learn.microsoft.com/dotnet/api/microsoft.odata.mcp.core.catalog.odatamcpinstructions.compose\(system.string\)). ### IsDynamicModel Gets or sets a value indicating whether the EDM can change while the catalog is alive. #### Syntax ```csharp theme={null} public bool IsDynamicModel { get; set; } ``` #### Property Value Type: `bool` #### Remarks When `false` (the default) type shapes are computed once at catalog construction and cached. Set to `true` for models whose declared members change at runtime so shapes are rebuilt per request. ### MaxCompletionValues Gets or sets the maximum number of entity-set completion values returned for an empty prefix. #### Syntax ```csharp theme={null} public int MaxCompletionValues { get; set; } ``` #### Property Value Type: `int` ### MaxExpandLength Gets or sets the maximum length of an `expand` argument. #### Syntax ```csharp theme={null} public int MaxExpandLength { get; set; } ``` #### Property Value Type: `int` ### MaxFilterLength Gets or sets the maximum length of a `filter` argument. #### Syntax ```csharp theme={null} public int MaxFilterLength { get; set; } ``` #### Property Value Type: `int` ### MaxOperationWait Gets or sets how long an annotated-action MCP task may wait for elicitation and the host waiter. Used as the task TTL when the Started ticket has no `expiresIn`. #### Syntax ```csharp theme={null} public System.TimeSpan MaxOperationWait { get; set; } ``` #### Property Value Type: `System.TimeSpan` #### Remarks Defaults to 10 minutes. `tasks/cancel` and this timeout cancel the waiter token. ### MaxRequestBodyBytes Gets or sets the maximum JSON body size in bytes for create, update, and operation calls. #### Syntax ```csharp theme={null} public int MaxRequestBodyBytes { get; set; } ``` #### Property Value Type: `int` ### MaxResources Gets or sets the maximum number of catalog resources, including `$metadata`. #### Syntax ```csharp theme={null} public int MaxResources { get; set; } ``` #### Property Value Type: `int` ### MaxResponseBytes Gets or sets the maximum response size in bytes before a tool result is rejected. #### Syntax ```csharp theme={null} public int MaxResponseBytes { get; set; } ``` #### Property Value Type: `int` ### MaxSelectLength Gets or sets the maximum length of a `select` argument. #### Syntax ```csharp theme={null} public int MaxSelectLength { get; set; } ``` #### Property Value Type: `int` ### RouteName Gets or sets the MCP resource route name (for example, "remote" or "odata"). #### Syntax ```csharp theme={null} public string RouteName { get; set; } ``` #### Property Value Type: `string` ### ToolsPageSize Gets or sets how many tools a full `tools/list` page returns. #### Syntax ```csharp theme={null} public int ToolsPageSize { get; set; } ``` #### Property Value Type: `int` #### Remarks Defaults to 100. The final page may be shorter. Clients must not assume this size. The value must be greater than zero. Set it before the catalog is built. A cursor issued for one size is rejected if the size later changes, because each cursor is an offset on that size. ## Methods ### Equals Inherited Virtual > [!NOTE] > > Inherited from `object` #### Syntax ```csharp theme={null} public virtual bool Equals(object obj) ``` #### Parameters | Name | Type | Description | | - | - | - | | `obj` | `object?` | - | #### Returns Type: `bool` ### Equals Inherited > [!NOTE] > > Inherited from `object` #### Syntax ```csharp theme={null} public static bool Equals(object objA, object objB) ``` #### Parameters | Name | Type | Description | | - | - | - | | `objA` | `object?` | - | | `objB` | `object?` | - | #### Returns Type: `bool` ### GetHashCode Inherited Virtual > [!NOTE] > > Inherited from `object` #### Syntax ```csharp theme={null} public virtual int GetHashCode() ``` #### Returns Type: `int` ### GetType Inherited > [!NOTE] > > Inherited from `object` #### Syntax ```csharp theme={null} public System.Type GetType() ``` #### Returns Type: `System.Type` ### MemberwiseClone Inherited > [!NOTE] > > Inherited from `object` #### Syntax ```csharp theme={null} protected internal object MemberwiseClone() ``` #### Returns Type: `object` ### ReferenceEquals Inherited > [!NOTE] > > Inherited from `object` #### Syntax ```csharp theme={null} public static bool ReferenceEquals(object objA, object objB) ``` #### Parameters | Name | Type | Description | | - | - | - | | `objA` | `object?` | - | | `objB` | `object?` | - | #### Returns Type: `bool` ### ToString Inherited Virtual > [!NOTE] > > Inherited from `object` #### Syntax ```csharp theme={null} public virtual string ToString() ``` #### Returns Type: `string?` This documentation is built and hosted on [Mintlify](https://mintlify.com), a developer documentation platform.
