MCP server manager for DeepSeek Harness — workspace mcp.json discovery, hot sync, and a web settings UI.
Overview
✅ Latest version has passed the compatibility test at A workspace-level MCP manager for DeepSeek Harness: it reads MCP servers from each workspace's .dsh/dshmm/mcp.json, registers their tools dynamically, and provides a management tab in the Web settings UI. Run the install command again to update: Create .dsh/dshmm/mcp.json at the workspace root: - A missing type is treated as Streamable HTTP; ${VAR} environment expansion is supported. - A stdio server without cwd uses the workspace root. - serverName is globally unique; duplicates are shown as conflicts. - Set "enabled": false to disable an entry without removing it; absent means enabled. - Workspace tools use the mcp__ naming convention. - Settings strict mode is used to mount only the selected workspace's servers. When modifying both deepseek-harness and this plugin from source, see the Source Developer Guide. Both repositories may be anywhere; they do not need to be siblings or use fixed paths.

Workspace configuration
Create .dsh/dshmm/mcp.json at the workspace root:
{
"mcpServers": {
"my-http-server": {
"type": "http",
"url": "http://127.0.0.1:8090/mcp"
},
"my-stdio-server": {
"type": "stdio",
"command": "npx",
"args": ["-y", ""]
}
}
}
Rules:
- A missing
typeis treated as Streamable HTTP;${VAR}environment expansion is supported. - A stdio server without
cwduses the workspace root. serverNameis globally unique; duplicates are shown as conflicts.- Set
