dsh-greatarrow — GreatArrow.ai memory for DeepSeek Harness

Connects DeepSeek Harness (dsh) to your GreatArrow.ai workspace through the GreatArrow.ai MCP server. Your agent can then search and save memories, read and update tasks, and resume earlier sessions. The same memory is shared with every other AI client you connect to GreatArrow.ai.

This is a configuration-only bundle. It adds one @deepseek-ai/dsh-mcp-client row (Streamable HTTP, https://www.greatarrow.ai/api/mcp) to your dsh composition. It ships no executable code and needs no build step.

Install

1. Get a token: sign in at greatarrow.ai/install/deepseek-harness.

2. Save it as the only content of ~/.dsh/great-arrow.token (or $DSH_HOME/great-arrow.token). Use an editor rather than a shell command, so the token stays out of your shell history. Then keep the file private:

   chmod 600 ~/.dsh/great-arrow.token
   

   The token is never written into the YAML. It is never read from an environment variable either: dsh also loads a .env from whatever folder you launch it in, which arrives with any cloned repository.

3. Install the plugin into the profile you run (dsh web boots web):

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

   If you use the dshmarket plugin and this entry is listed there, Settings → Plugin Market installs it with one click.

4. Restart dsh. The tools appear as mcp__great-arrow__<tool>, for example mcp__great-arrow__memory_search, mcp__great-arrow__memory_create, mcp__great-arrow__todo_list. The server's instructions join the system prompt, so the agent knows when to search and when to save.

Check it works

dsh --profile web --dump-config | grep -A8 great-arrow-memory

Then, in a new session, ask: "What do you know about my workspace?" The agent should call mcp__great-arrow__memory_search.

Already ran the GreatArrow.ai installer?

The installer (Arrow Setup) writes the same token file and the same row into ~/.dsh/cordis.patch.yml, which covers every profile. Use the installer or this plugin, not both. Two rows with the same server name make the second one fail to load. When the installer sees this plugin in a profile, it writes only the token.

Security

• The URL is fixed to https://www.greatarrow.ai/api/mcp, and the token is read only from great-arrow.token in the dsh home. dsh lets only your launching environment set DSH_HOME, so a project .env cannot move the file or swap in another account.
• Versions before 2026-10-02 read GREAT_ARROW_TOKEN and GREAT_ARROW_URL from the environment. If you installed one and ever launched dsh inside an untrusted repository, revoke the token at greatarrow.ai/account/connections and create a new one.

Uninstall

dsh plugin --profile web remove dsh-greatarrow

Then delete ~/.dsh/great-arrow.token, and revoke the token at greatarrow.ai/account/connections.
