Do I need an OpenRouter API key?

Yes, both models are accessed through OpenRouter's unified API. Set `OPENROUTER_API_KEY` in your `.env` file.

What are the context limits?

DeepSeek uses 50,000 characters for focused reasoning; Claude uses 600,000 characters for comprehensive responses.

What credentials does it need?

It reads `OPENROUTER_API_KEY` from the environment. Store these in your client's env block or a secrets manager — never commit them to a repository — and grant the narrowest scope that still covers your use case.

What is the Deepseek MCP Server?

🧠 MCP server implementing RAT (Retrieval Augmented Thinking) - combines DeepSeek's reasoning with GPT-4/Claude/Mistral responses, maintaining conversation context

The short version

A Model Context Protocol (MCP) server that combines DeepSeek R1's reasoning capabilities with Claude 3.5 Sonnet's response generation through OpenRouter. This implementation uses a two-stage process where DeepSeek provides structured reasoning which is then incorporated into Claude's response generation.

Two-Stage Processing —
Uses DeepSeek R1 for initial reasoning (50k character context)
Uses Claude 3.5 Sonnet for final response (600k character context)
Both models accessed through OpenRouter's unified API
Injects DeepSeek's reasoning tokens into Claude's context
Smart Conversation Management —

Frequently asked questions

DeepSeek R1 first generates reasoning tokens, then Claude 3.5 Sonnet uses those as context to produce the final response.
