SourceExplorerMcp 1.0.2

SourceExplorerMcp

MCP tools for exploring source code of .NET assemblies via decompilation

What is SourceExplorerMcp

SourceExplorerMcp is a Model Context Protocol (MCP) server distributed as a dotnet tool. It lets AI agents explore and decompile .NET types from a project's dependency graph — NuGet packages and framework assemblies — without needing the original source code.

Point it at any .NET project directory, and the server will resolve the project's dependencies, scan for assemblies, and expose tools that let an agent search for types and decompile them into readable C# source.

How it works

1. Parses project.assets.json to map DLL filenames to NuGet packages.
2. Scans bin/ directories for matching .dll files.
3. Indexes types via System.Reflection.Metadata.
4. Decompiles on demand via ICSharpCode.Decompiler.

Assembly and type data are cached in memory, so repeated tool calls against the same project are fast.

Installation

Prerequisites

• .NET 10 SDK

Configure the MCP server in your client

Claude Code:

claude mcp add source-explorer -- dotnet dnx SourceExplorerMcp --yes

You can also add --scope local, --scope user or --scope project to the above command. It defaults to local if not specified.

Standard Config (works in most MCP clients):

{
    "mcpServers": {
        "source-explorer": {
            "type": "stdio",
            "command": "dotnet",
            "args": [
                "dnx",
                "SourceExplorerMcp",
                "--yes"
            ]
        }
    }
}
