## Definition

**Assembly:** Microsoft.OData.Mcp.Core.dll

**Namespace:** Microsoft.OData.Mcp.Core.Catalog

**Inheritance:** System.Object

## Syntax

```csharp theme={null}
Microsoft.OData.Mcp.Core.Catalog.EdmModelShape
```

## Summary

Renders the whole-service map behind `odata_describe_model`: a summary of sets and navigations, a complete
dump of every in-scope type, a relationship-only mermaid diagram, and the unbound operation list.

## Remarks

This is the context-sized stand-in for `$metadata`. Every shape is composed from the cached
[EdmTypeShape](https://ai.easyaf.dev/odata-mcp/api-reference/Microsoft/OData/Mcp/Core/Catalog/EdmTypeShape.md) instances so `odata_describe_type`, type cards, and the model map never disagree.

## Methods

###  RenderCompleteJson

Renders the complete model as compact JSON: every in-scope type body, the complex types they use, and unbound operations.

#### Syntax

```csharp theme={null}
public static string RenderCompleteJson(Microsoft.OData.Mcp.Core.Catalog.ODataMcpCatalog catalog, System.Collections.Generic.IReadOnlyList<Microsoft.OData.Mcp.Core.Models.EdmEntitySet> sets)
```

#### Parameters

| Name | Type | Description |
| - | - | - |
| `catalog` | `Microsoft.OData.Mcp.Core.Catalog.ODataMcpCatalog` | The catalog. |
| `sets` | `System.Collections.Generic.IReadOnlyList<Microsoft.OData.Mcp.Core.Models.EdmEntitySet>` | The in-scope entity sets. |

#### Returns

Type: `string`
`{ "types": {...}, "complexTypes"?: {...}, "operations"?: {...} }`.

#### Exceptions

| Exception | Description |
| - | - |
| `ArgumentNullException` | Thrown when *catalog* or *sets* is null. |

### &#x20;RenderCompleteText

Renders the complete model as text: every in-scope type in the declaration grammar, the complex types they use, then unbound operations.

#### Syntax

```csharp theme={null}
public static string RenderCompleteText(Microsoft.OData.Mcp.Core.Catalog.ODataMcpCatalog catalog, System.Collections.Generic.IReadOnlyList<Microsoft.OData.Mcp.Core.Models.EdmEntitySet> sets)
```

#### Parameters

| Name | Type | Description |
| - | - | - |
| `catalog` | `Microsoft.OData.Mcp.Core.Catalog.ODataMcpCatalog` | The catalog. |
| `sets` | `System.Collections.Generic.IReadOnlyList<Microsoft.OData.Mcp.Core.Models.EdmEntitySet>` | The in-scope entity sets. |

#### Returns

Type: `string`
Blank-line separated blocks, LF endings, no trailing newline.

#### Exceptions

| Exception | Description |
| - | - |
| `ArgumentNullException` | Thrown when *catalog* or *sets* is null. |

### &#x20;RenderMermaid

Renders a relationship-only mermaid `erDiagram` for the in-scope types.

#### Syntax

```csharp theme={null}
public static string RenderMermaid(Microsoft.OData.Mcp.Core.Catalog.ODataMcpCatalog catalog, System.Collections.Generic.IReadOnlyList<Microsoft.OData.Mcp.Core.Models.EdmEntitySet> sets)
```

#### Parameters

| Name | Type | Description |
| - | - | - |
| `catalog` | `Microsoft.OData.Mcp.Core.Catalog.ODataMcpCatalog` | The catalog. |
| `sets` | `System.Collections.Generic.IReadOnlyList<Microsoft.OData.Mcp.Core.Models.EdmEntitySet>` | The in-scope entity sets. |

#### Returns

Type: `string`
One `A ||--o{ B : Nav` line per navigation (`||--o|` for single targets) and a bare entity line for types with no navigations.

#### Exceptions

| Exception | Description |
| - | - |
| `ArgumentNullException` | Thrown when *catalog* or *sets* is null. |

#### Remarks

No attribute compartments, whatever the requested detail. Names that are not mermaid-safe are quoted.

### &#x20;RenderOperationLines

Renders the unbound operations block for text shapes.

#### Syntax

```csharp theme={null}
public static System.Collections.Generic.IReadOnlyList<string> RenderOperationLines(Microsoft.OData.Mcp.Core.Models.EdmModel model)
```

#### Parameters

| Name | Type | Description |
| - | - | - |
| `model` | `Microsoft.OData.Mcp.Core.Models.EdmModel` | The Core EDM. |

#### Returns

Type: `System.Collections.Generic.IReadOnlyList<string>`
`operations` followed by one indented signature per unbound operation, or an empty list when none are declared.

#### Exceptions

| Exception | Description |
| - | - |
| `ArgumentNullException` | Thrown when *model* is null. |

### &#x20;RenderOperationsJson

Renders the unbound operations as a name-to-signature map.

#### Syntax

```csharp theme={null}
public static System.Collections.Generic.Dictionary<string, string> RenderOperationsJson(Microsoft.OData.Mcp.Core.Models.EdmModel model)
```

#### Parameters

| Name | Type | Description |
| - | - | - |
| `model` | `Microsoft.OData.Mcp.Core.Models.EdmModel` | The Core EDM. |

#### Returns

Type: `System.Collections.Generic.Dictionary<string, string>`

#### Exceptions

| Exception | Description |
| - | - |
| `ArgumentNullException` | Thrown when *model* is null. |

### &#x20;RenderSummaryJson

Renders the model summary as compact JSON: every in-scope set with its type, key, docs, and navigations, then unbound operations.

#### Syntax

```csharp theme={null}
public static string RenderSummaryJson(Microsoft.OData.Mcp.Core.Catalog.ODataMcpCatalog catalog, System.Collections.Generic.IReadOnlyList<Microsoft.OData.Mcp.Core.Models.EdmEntitySet> sets)
```

#### Parameters

| Name | Type | Description |
| - | - | - |
| `catalog` | `Microsoft.OData.Mcp.Core.Catalog.ODataMcpCatalog` | The catalog. |

#### Returns

Type: `string`
`{ "sets": { "Customers": { "type", "key", "description"?, "navs"? } }, "operations"?: {...} }`.

#### Exceptions

| Exception | Description |
| - | - |
| `ArgumentNullException` | Thrown when *catalog* or *sets* is null. |

### &#x20;RenderSummaryText

Renders the model summary as text: one header per in-scope set with at most one doc line and its navigations, then unbound operations.

#### Syntax
