Analyze a .NET memory dump (core file, .dmp) with the dndump CLI from the shell. Use whenever the task involves investigating a .NET/CLR crash dump, OOM, memory leak, hang, deadlock, or unhandled exception, or when a dump file path or dndump/SOS-style command (dumpheap, gcroot, clrstack, syncblk, pe, ...) is…

Instructions for frankbolero/dotnet-dump-mcp, a project described as: 🤖 An AI-native CLI Tool and MCP server for .NET memory dump investigations. Leverage LLMs (Claude/Gemini) to analyze heaps, threads, and exceptions using natural language. Built with ClrMD, token-efficient paging, and Docker support for…
Command
Lists the managed modules in the process.
Command
Displays managed call stacks for all threads or a specific thread.
Command
Lists all managed threads in the process.
Command
Command "dumpassembly" from frankbolero/dotnet-dump-mcp, covering dumpassembly, usage and clrmd implementation.
Command
Digs into .NET type metadata. Displays information about an EEClass structure.
Command
Analyzes managed heap objects, identifies memory leaks, and traces object references.
Command
Displays details about method descriptors (MethodDesc).
Command
Command "dumpmodule" from frankbolero/dotnet-dump-mcp, covering dumpmodule, usage and clrmd implementation.
Command
Displays details about method tables (MethodTable).
Command
Displays details about a managed object.
Command
Helps examine thread call stacks. While clrstack is more commonly used for managed call stacks, dumpstack can also be used to inspect stack frames, including native ones.
Command
Displays information about the managed heap, including memory usage for each generation (Gen 0, Gen 1, Gen 2, and Large Object Heap).
Command
Examines thread call stacks. Displays the merged threads stack, similar to the "Parallel Stacks" panel in Visual Studio.
Command
Displays statistics about garbage collector handles.
Command
Displays information about references (or roots) to a specified object. It helps in identifying what is keeping an object alive in the managed heap.
Command
Lists available commands or provides detailed help on a specific command.
Command
Displays the MethodDesc structure at a specified address (Instruction Pointer).
Command
Displays the MethodTable and MethodDesc structures for a specified method or type name.
Command
Prints information about an exception object.
Command
Loads the SOS debugging extension for detailed analysis.
Command
Displays information about synchronization blocks (thin locks and System.Threading.Monitor instances). Useful for diagnosing deadlocks and contention issues.
