dsh-mcp-adapter

Use MCP servers with DeepSeek Harness without burning the context window.

One mcp proxy tool. Lazy server start. On-demand search / describe / call.

Why this exists

DeepSeek Harness already ships @deepseek-ai/dsh-mcp-client. That client connects at startup and registers every advertised MCP tool as a native mcp____ function. Schema cost is paid on every request.

This adapter follows the pi-mcp-adapter contract instead:

• one mcp proxy tool instead of hundreds of schemas
• lazy server start
• on-demand search / describe / call
• standard .mcp.json / ~/.config/mcp/mcp.json discovery
• optional directTools promotion for hot-path tools
• metadata cache so search works before a live connect

It is an independent plugin. It is not affiliated with DeepSeek AI.

Do not mount this adapter and @deepseek-ai/dsh-mcp-client against the same servers. They would double-connect and fight over names.

Install

dsh plugin --profile web add dsh-mcp-adapter

Restart the profile (dsh web / dsh tui) after install.

Quick start

Preferred project config: .mcp.json

{
  "mcpServers": {
    "chrome-devtools": {
      "command": "npx",
      "args": ["-y", "chrome-devtools-mcp@1.6.0"]
    }
  }
}

Then:

mcp({ search: "screenshot" })
mcp({ describe: "chrome-devtools_take_screenshot" })
mcp({ tool: "chrome-devtools_take_screenshot", args: { format: "png" } })

args can be a JSON object or a JSON string.
