Local Shell MCP: Enabling Controlled Shell and File Workspaces for DSH

local-shell-mcp is an MCP control plane maintained by fwerkor, offering clients controlled shell, file, browser automation, and remote worker capabilities. When used as a DeepSeek Harness plugin, it fully bridges the mcp__lsm__ tool interface via HTTP, binding each DSH session to an independent logical session and live workspace. The article introduces the recommended topology, steps to start LSM before installing the plugin, environment variable configuration, and typical usage, and explains that the plugin runs with DSH process permissions, requiring verification of source code and security boundaries before installation.
