How to Set Up and Use Sequential Thinking Multi-Agent System
Sequential Thinking Multi-Agent System (MAS) is a Python MCP server that implements deep, structured reasoning by coordinating a team of six specialized AI agents — Factual, Emotional, Critical, Optimistic, Creative, and Synthesis — each analyzing a problem from a distinct cognitive perspective before the Synthesis agent integrates their outputs into a final answer. Four of the six agents can perform live web research via the Exa search API, making the system well-suited for complex, multi-faceted questions that benefit from independent verification and adversarial critique. Developers and researchers use it to augment Claude and other MCP clients with a high-quality reasoning layer for code analysis, architectural decisions, and research tasks.
Prerequisites
- Python 3.10 or higher with pip or uv package manager
- An API key for at least one supported LLM provider: DeepSeek (DEEPSEEK_API_KEY), Groq (GROQ_API_KEY), OpenRouter (OPENROUTER_API_KEY), GitHub Models (GITHUB_TOKEN), or Anthropic (ANTHROPIC_API_KEY)
- Optional: An Exa API key (EXA_API_KEY) to enable web research capabilities for the Factual, Critical, Optimistic, and Creative agents
- An MCP-compatible AI client such as Claude Desktop or Cursor
Install via Smithery (recommended)
The easiest installation method is via the Smithery CLI, which handles all dependencies and registers the server with your Claude Desktop client automatically.
npx -y @smithery/cli install @FradSer/mcp-server-mas-sequential-thinking --client claudeManual installation with pip or uv
Alternatively, clone the repository and install the Python package directly. Using uv is recommended for faster dependency resolution.
git clone https://github.com/FradSer/mcp-server-mas-sequential-thinking.git
cd mcp-server-mas-sequential-thinking
uv pip install .
# Or with pip:
pip install .Set required environment variables
Export the LLM provider environment variable and the corresponding API key. Set LLM_PROVIDER to your chosen provider name (deepseek, groq, openrouter, github, anthropic, or ollama). Optionally add EXA_API_KEY to enable web research.
export LLM_PROVIDER=deepseek
export DEEPSEEK_API_KEY=your_deepseek_api_key
export EXA_API_KEY=your_exa_api_key # optionalAdd the MCP server to your AI client configuration
Open your AI client's MCP configuration file and add an entry for the sequential thinking server. Include the LLM_PROVIDER and API key in the env block.
{
"mcpServers": {
"sequential-thinking": {
"command": "mcp-server-mas-sequential-thinking",
"env": {
"LLM_PROVIDER": "deepseek",
"DEEPSEEK_API_KEY": "your_api_key",
"EXA_API_KEY": "your_exa_key_optional"
}
}
}
}Restart your AI client and test
Restart your AI client and invoke the 'sequentialthinking' tool on a complex question. Note that each run involves six specialist agents in parallel, so expect higher latency and 5-10x more token usage than a direct answer.
Sequential Thinking Multi-Agent System Examples
Client configuration
Claude Desktop configuration using DeepSeek as the LLM provider with optional Exa web research. Swap LLM_PROVIDER and the API key to use a different provider.

}Prompts to try
Use the sequentialthinking tool for questions that benefit from multiple perspectives and deep analysis. Best suited for complex, open-ended problems.

LLM_PROVIDER is set but the server errors with an authentication failure
Check that the API key environment variable name matches the provider: DEEPSEEK_API_KEY for deepseek, GROQ_API_KEY for groq, OPENROUTER_API_KEY for openrouter, GITHUB_TOKEN for github, and ANTHROPIC_API_KEY for anthropic. All are conditional on which provider you set.
Requests time out or take an extremely long time
The system runs up to six agents in parallel, some with 240-second timeouts (Creative agent). This is expected behavior. If using Groq, the rate limits may cause slowdowns on the free tier — switch to DeepSeek or OpenRouter for higher throughput. Consider whether the simpler sequential thinking MCP server is a better fit for your use case.
Web research returns no results even though EXA_API_KEY is set
Verify your Exa API key is valid by testing it directly against the Exa API. Confirm EXA_API_KEY is correctly spelled in the env block of your MCP config. The Exa key is used by four of the six agents (Factual, Critical, Optimistic, Creative) — if those agents still produce output without web results, the key may have expired or reached its quota.
