1 Mint your free trial key

One click, no email to start. The key works in DeepSeek Harness's MCP config right away. Without an email it gets 15 free calls a day. Bind an email (free, no card) and the same key keeps working, at 50 requests/day for the rest of its 7-day trial.

2 Add to your DeepSeek Harness config

Paste into your harness profile YAML (the plugins list) (macOS/Linux) · your harness profile YAML (the plugins list) (Windows)

DeepSeek’s consumer chat (chat.deepseek.com) has no MCP UI — there is nowhere to paste this, and no card here will change that. Three places a DeepSeek user can hold a DC Hub key today: this harness (below), Cursor pointed at a DeepSeek model, or the DeepSeek tool-calling API with DC Hub behind an MCP bridge — the API speaks OpenAI-style function calling, not MCP, so something has to translate. Same endpoint, same key, in all three.

- id: mcp-dchub
  name: '@deepseek-ai/dsh-mcp-client'
  config:
    serverName: dchub
    transport: streamable-http
    url: https://dchub.cloud/mcp
    headers:
      X-API-Key: "{{TRIAL_KEY}}"

After saving, restart DeepSeek Harness and DC Hub will appear in the MCP connector list.
