Install for DeepSeek Harness

DeepSeek's open-source agent harness (dsh). Arrow Setup writes ~/.dsh for you, or install the GreatArrow.ai plugin from the Plugin Market.

You can read the DeepSeek Harness setup steps without signing in.

Sign in when you are ready to create a private token, or replace the placeholder in the command below with an existing Great Arrow token.

Step 1 · Get your secure link

The install command below is public, but DeepSeek Harness needs its own private link before it can access your Great Arrow workspace. Sign in to create one, or paste an existing link code anywhere you see gad_PASTE_YOUR_TOKEN.

Step 2 · Add it to DeepSeek Harness

Fastest: Arrow Setup finds dsh and writes both files below for every dsh profile. Or set it up by hand: your private link goes in one file, and dsh reaches GreatArrow.ai through the plugin or a YAML row. Use the plugin or the row, not both.

1. Put your private link in ~/.dsh/.env, then run chmod 600 on it

~/.dsh/.envbash

GREAT_ARROW_TOKEN=gad_PASTE_YOUR_TOKEN

2. Install the GreatArrow.ai plugin

Terminalbash

dsh plugin --profile web add github:GreatArrow-ai/dsh-greatarrow

Source: github.com/GreatArrow-ai/dsh-greatarrow. dsh web runs the web profile.

Or, instead of step 2, add this row to ~/.dsh/cordis.patch.yml

~/.dsh/cordis.patch.ymlyaml

- insert:
    - id: great-arrow-memory
      name: '@deepseek-ai/dsh-mcp-client'
      config:
        serverName: great-arrow
        transport: streamable-http
        url: 'https://www.greatarrow.ai/api/mcp'
        headers:
          Authorization: !!js '`Bearer ${process.env.GREAT_ARROW_TOKEN ?? ""}`'
          X-MCP-Client: 'deepseek-harness'
          X-GAD-Install-Version: '2026.08.08'

Restart dsh. In a new session, ask what it knows about your workspace; it should call mcp__great-arrow__memory_search.
