generate_diagrammer

Decompilation

Creates an interactive HTML visualization of type relationships within a .NET assembly. The diagram shows inheritance hierarchies, interface implementations, and namespace organization. Open the generated file in any browser to explore the type graph.

Parameters

Parameter	Type	Required	Default	Description
assembly_path	string	Yes	—	Path to the .dll or .exe file
output_dir	string|null	No	null	Where to save the HTML file (defaults to a diagrammer folder next to the assembly)
include_pattern	string|null	No	null	Regex to include only matching types (e.g., "MyApp\\.Services\\..+")
exclude_pattern	string|null	No	null	Regex to exclude matching types (e.g., ".*Generated.*")

Example

MCP JSON

{
  "tool": "generate_diagrammer",
  "arguments": {
    "assembly_path": "/path/to/MyApp.dll",
    "include_pattern": "MyApp\\.Core\\..+",
    "exclude_pattern": ".*Tests.*"
  }
}

Python

result = await client.call_tool("generate_diagrammer", {
    "assembly_path": "/path/to/MyApp.dll",
    "include_pattern": r"MyApp\.Core\..+",
    "exclude_pattern": r".*Tests.*",
})

Response

Returns the path to the generated HTML file along with the output directory. Open the HTML file in a web browser to interactively explore type inheritance, interface implementation, and namespace structure.

Usage tips

• Use include_pattern to focus on a specific namespace and keep the diagram readable.
• Use exclude_pattern to hide compiler-generated types or test fixtures.
• For very large assemblies, combine both patterns to produce a focused diagram rather than an overwhelming one.
