search_types

Decompilation

Searches for types whose names match a given pattern. Faster than listing all types when you know what you are looking for. Supports substring matching, regex, namespace filtering, and entity type filtering. Results are grouped by namespace.

Parameters

Parameter	Type	Required	Default	Description
`assembly_path`	`string`	Yes	—	Path to the `.dll` or `.exe` file
`pattern`	`string`	Yes	—	Search pattern to match against type names
`namespace_filter`	`string\|null`	No	`null`	Only return types in namespaces containing this string
`entity_types`	`string[]`	No	all	Types to search: `class`, `interface`, `struct`, `delegate`, `enum`
`case_sensitive`	`bool`	No	`false`	Case-sensitive pattern matching
`use_regex`	`bool`	No	`false`	Treat pattern as a regular expression

Example

MCP JSON
Python

{
  "tool": "search_types",
  "arguments": {
    "assembly_path": "/path/to/MyApp.dll",
    "pattern": "Service",
    "namespace_filter": "MyApp.Core",
    "entity_types": ["class", "interface"]
  }
}

result = await client.call_tool("search_types", {
    "assembly_path": "/path/to/MyApp.dll",
    "pattern": "Service",
    "namespace_filter": "MyApp.Core",
    "entity_types": ["class", "interface"],
})

Response

Returns matching types grouped by namespace. Each entry shows the type name, fully qualified name, and kind. Supports pagination via max_results and offset.

list_types — list all types without filtering
decompile_assembly — decompile the types you find
search_methods — search for methods instead of types
