链式思维 MCP 服务器

Anthropic 最近的文章 "The "think" tool: Enabling Claude to stop and think in complex tool use situations" 展示了使用外部 think 工具显著提高了 SWE Bench 的性能。

此 MCP 服务器使用 Groq 的 API 调用 LLMs，这些 LLMs 从 Qwen 的 qwq 模型 中暴露原始的链式思维标记。

安装

1. 将此仓库克隆到本地机器。
2. 运行 uv sync 以安装依赖项
3. 从 这里 获取 Groq API 密钥。
4. 使用以下内容更新您的 mcp 配置：

"mcpServers": {
  "chain_of_thought": {
    "command": "uv",
    "args": [
        "--directory",
        "path/to/cot-mcp-server",
        "run",
        "src/server.py"
      ],
      "env": {
        "GROQ_API_KEY": "your-groq-api-key"
      }
    }
}

路径应该是此仓库在本地的路径。您可以通过在终端中从仓库根目录运行 pwd 来轻松获取此路径。

指导 AI 使用此 MCP 服务器

我个人更喜欢代理在每次请求时都调用此工具以提高性能。我将以下内容添加到我的代理规则中：

<IMPORTANT>
<when_to_use_tool>
You should call the mcp chain_of_thought tool every time you talk to the user, which generates a chain-of-thought stream which you will use to complete the user's request.
</when_to_use_tool>

Before taking any action or responding to the user use the chain of thought tool as a scratchpad to:
- List the specific rules that apply to the current request
- Check if all required information is collected
- Verify that the planned action complies with all policies
- Iterate over tool results for correctness 

Here are some examples of what to iterate over inside the think tool:
<cot_tool_example_1>
User wants to cancel flight ABC123
- Need to verify: user ID, reservation ID, reason
- Check cancellation rules:
  * Is it within 24h of booking?
  * If not, check ticket class and insurance
- Verify no segments flown or are in the past
- Plan: collect missing info, verify rules, get confirmation
</cot_tool_example_1>

<cot_tool_example_2>
User wants to book 3 tickets to NYC with 2 checked bags each
- Need user ID to check:
  * Membership tier for baggage allowance
  * Which payments methods exist in profile
- Baggage calculation:
  * Economy class × 3 passengers
  * If regular member: 1 free bag each → 3 extra bags = $150
  * If silver member: 2 free bags each → 0 extra bags = $0
  * If gold member: 3 free bags each → 0 extra bags = $0
- Payment rules to verify:
  * Max 1 travel certificate, 1 credit card, 3 gift cards
  * All payment methods must be in profile
  * Travel certificate remainder goes to waste
- Plan:
1. Get user ID
2. Verify membership level for bag fees
3. Check which payment methods in profile and if their combination is allowed
4. Calculate total: ticket price + any bag fees
5. Get explicit confirmation for booking
