Install & config

Client config (built from the install command this repo gives)

{
  "mcpServers": {
    "deepseek-ai-deepseek-harness": {
      "command": "npx",
      "args": ["@deepseek-ai/dsh"]
    }
  }
}

Parsed from the README we fetched on 2026-10-26; we have not executed it.

command/args come from the install command the repository states. When it is ambiguous, the project README wins.

VS Code (.vscode/mcp.json - the key is servers)

{
  "servers": {
    "deepseek-ai-deepseek-harness": {
      "command": "npx",
      "args": ["@deepseek-ai/dsh"]
    }
  }
}

Same server, but VS Code keeps it under <code>servers</code>.

Claude Code (command line)

claude mcp add --transport stdio deepseek-ai-deepseek-harness -- npx @deepseek-ai/dsh

Claude Code does not read a config file; add the server with this command.

# DeepSeek Harness

以下摘录自该仓库的 README（片段） · 在 GitHub 读完整 README →

English | 中文
DeepSeek Harness (dsh) is an open-source agent harness developed by DeepSeek AI.
It is built on an everything-is-a-plugin architecture and powered by Cordis, whose design is described in A Programming Paradigm for Spatiotemporal Composability.
Documentation: https://deepseek-harness.github.io/deepseek-harness/
## Developer preview
DeepSeek Harness is in developer preview and iterating rapidly. THERE WILL BE COMPATIBILITY-BREAKING CHANGES.
Review the safety notice before running the project.
## Run
### Run from npm
Install Node.js, then run:
sh
npx @deepseek-ai/dsh web
The command starts the Web UI at http://127.0.0.1:3080 by default and opens it in the default browser for a local launch. An SSH launch only prints the host URL because the SSH client or editor owns the local forwarded address. Pass --no-open to run the server without opening a browser. See Web UI guide.
### Run from source
To run from a repository checkout:
sh
git clone https://github.com/deepseek-ai/deepseek-harness.git
cd deepseek-harness
pnpm install
pnpm run build
pnpm dsh web
pnpm run build prepares the repository artifacts. pnpm dsh web uses those built artifacts without rebuilding.
## Community and support
Submit feedback or bug reports through GitHub Discussions.
Add the dsh-plugin topic to your plugin repository for discoverability.
Join DeepSeek Harness Discord community .
## Contributing
See CONTRIBUTING.md.
## Development
Start with the development guide and architecture documentation.
pnpm run dev:web builds, serves, and rebuilds client bundles on source edits in one terminal, and make help lists the matching Make targets for Web and Desktop; the guide's application commands section owns the full table.
For agents, follow AGENTS.md.
