Exoproc MCP server lets Claude Code inspect live process memory

Open-source stdio MCP server built by a Reddit user connects Claude Code to live process memory, moving past static decompilation analysis. The post argues static analysis only shows what code might do offline, so prompts simulating execution should be replaced with live memory access.
