思路链 MCP 服务器

Anthropic 最近发表的文章“思考工具：让 Claude 在复杂的工具使用情况下停下来思考”表明，使用外部think工具可以显著提高SWE Bench的性能。

该 MCP 服务器使用 Groq 的 API 来调用 LLM，从而公开来自 Qwen 的qwq 模型的原始思路链标记。

安装

将此存储库克隆到您的本地机器。
运行uv sync来安装依赖项
从这里获取 Groq API 密钥。
使用以下命令更新您的 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"
      }
    }
}

该路径应为该仓库的本地路径。您可以通过在仓库根目录下的终端中运行pwd轻松获取该路径。

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

<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
