DeepSeek Harness setup

DeepSeek Harness (dsh) is an open-source agent runtime. It already includes a generic MCP client — you only add a server config. This uses the same PartnerBoost MCP URL and AI Access Key as ChatGPT / Codex.

DeepSeek Harness is currently a Developer Preview.

Step 1 — Copy your AI Access Key

1. Log in to PartnerBoost.
2. Open AI Center → AI Connect (app.partnerboost.com/brand/ai-center/connect).
3. Copy your AI Access Key.

Step 2 — Start DeepSeek Harness

The UI defaults to http://127.0.0.1:3080. See the Harness docs for install details.

Step 3 — Add the PartnerBoost MCP server

In your profile, edit cordis.patch.yml (under $DSH_HOME/profiles/<name>/) and add:

- id: mcp-pb-brand
  name: '@deepseek-ai/dsh-mcp-client'
  config:
    serverName: pb-brand
    transport: streamable-http
    url: https://app.partnerboost.com/agent/mcp
    headers:
      Authorization: Bearer YOUR_AI_ACCESS_KEY
    toolCallTimeoutMs: 300000

Replace YOUR_AI_ACCESS_KEY with the key from AI Center → AI Connect. Keep the Bearer prefix.

toolCallTimeoutMs: 300000 (5 minutes) is recommended — publisher / influencer search can take longer than the dsh default (~60s).

Then restart Harness (or reload the profile) so it rediscovers tools.

Step 4 — Verify

Ask:

List my recent PartnerBoost transactions.

The client should call tools such as pb_get_transaction_list. After reconnecting, names use the pb_ prefix. See MCP features.

Troubleshooting

Symptom	Fix
401 Unauthorized	Check the key and the Bearer prefix
Timeout on media search	Keep toolCallTimeoutMs: 300000
Old tool names	Restart Harness so tools/list refreshes
