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 10 free calls. Bind an email (free, no card) and the same key keeps working, at 50 requests/day for the rest of its 7-day trial. Free calls are counted per network: if this one has already used them, a new key needs the email from its first call.

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.
