MCP management console for the official DeepSeek Harness MCP client: /mcp command with health diagnostics and pipeline trial calls, a Settings MCP tab with server CRUD (approval-gated writes, automatic backups) and a tool trial console over the official tool pipeline (Apache-2.0, dsh-plugin).
DeepSeek Harness MCP tool search for large catalogs: 1,000 MCP tools behind 2 MCP-facing schemas, exact-schema calls, allow/deny controls, and a local calculator.
Per-project MCP loading for DeepSeek Harness: drop a .dsh/mcp.json into a project and its sessions get the MCP servers' tools automatically — with live config reload. Client bridge, not an MCP server.
