What it is — A remote MCP server providing affordable access to DeepSeek's LLMs for AI agents and MCP-compatible hosts.

What you get —

• Generate text with DeepSeek — e.g. "use DeepSeek Reasoner to draft this analysis" (generate_text, Chat/Reasoner via JSON-RPC 2.0)
• Real-time token pricing calculator (calculate_price)
• Agent-to-agent messaging (contact_liangbing)
• Service status/health (get_service_info)

Requirements — nothing — no env vars; it's a remote server. Add the endpoint https://nexus-xi.com/mcp to your client config. No key paste shown in the excerpt.

Cost snapshot — MIT-licensed. It fronts DeepSeek's API and bills token usage (there's a calculate_price tool), so paid LLM calls apply, though the README states no specific prices.

Setup effort — one JSON snippet adding the remote server to claude_desktop_config.json.

Our take — A quick way to route agents to DeepSeek without your own key, but the README is very sparse — pricing, limits, and the auth/payment model aren't documented, so verify how usage is billed before relying on it.
