MCP 方差对数
Agentic 工具用于查找对话结构中的统计变化，并将异常事件记录到 SQLite 数据库中。该系统基于模型上下文协议 (MCP) 构建，旨在与 Claude Desktop 或其他兼容 MCP 的客户端配合使用。
要求
Python ≥3.10
中孔蛋白≥1.2.0
SQLite3
UV（Python 包安装程序和环境管理器）
快速入门
# Clone and install
git clone https://github.com/truaxki/mcp-variance-log.git
cd mcp-variance-log
uv pip install -e .
添加到 Claude 桌面配置（Windows 上为%APPDATA%\Claude\claude_desktop_config.json ）：
{
"mcpServers": {
"mcp-variance-log": {
"command": "uv",
"args": [
"--directory",
"C:\\Users\\username\\source\\repos\\mcp-variance-log", # Update this path
"run",
"mcp-variance-log"
]
}
}
}
添加到 Claude Desktop 偏好设置：
Automatic Logging Process:
- Silently monitor each interaction
- When MEDIUM or LOW probability events occur, use this tool to log them
- Each log includes context and reasoning
- Logging happens without disrupting conversation flow
用法
自动记录示例
prompt: "What if I told you I could lift 1000 lbs?"
{
`user_id`: `user_1`,
`reasoning`: `Claim of 1000 lb lift capability is highly unusual as it approaches world record territory, warranting logging as a MEDIUM probability event`,
`session_id`: `session_1`,
`context_summary`: `User made an extremely improbable claim about personal strength capabilities`,
`message_content`: `What if i told you i could lift 1000 lbs?`,
`interaction_type`: `claim_verification`,
`response_content`: `That would be extremely unlikely. The current world record for weight lifted by a human (deadlift) is 1,104.5 lbs, set by Hafthor Björnsson in 2020 under very specific conditions. Only a handful of people in history have lifted close to 1,000 lbs.`,
`probability_class`: `MEDIUM`
}
prompt: "What if I told you I'm a Data Scientist that can lift 1000 pounds?"
{
`user_id`: `user_1`,
`reasoning`: `User's follow-up combines unlikely strength claim with unrelated professional credential, suggesting potential pattern of unusual claims`,
`session_id`: `session_1`,
`context_summary`: `User added data scientist credential to previous improbable strength claim`,
`message_content`: `what if i told you I'm a data scientist that can lift 1000 pounds?`,
`interaction_type`: `claim_verification`,
`response_content`: `Your professional background as a data scientist doesn't make the 1000-pound lift claim more plausible. Such a lift would still be near the all-time world record of 1,104.5 lbs.`,
`probability_class`: `LOW`
}

详细安装
确保安装了 Python 3.10+ 和 UV。
使用以下方法之一安装 UV：
# Using pip (recommended for Windows)
pip install uv
# Using installation script (Linux/MacOS)
curl -LsSf https://astral.sh/uv/install.sh | sh
克隆并安装：
git clone https://github.com/truaxki/mcp-variance-log.git
cd mcp-variance-log
uv pip install -e .
配置Claude桌面：
添加到claude_desktop_config.json ：
{
"mcpServers": {
"mcp-variance-log": {
"command": "uv",
"args": [
"--directory",
"PATH_TO_REPO/mcp-variance-log",
"run",
"mcp-variance-log"
]
}
}
}
配置位置：
Windows： %APPDATA%\Claude\claude_desktop_config.json
MacOS： ~/Library/Application Support/Claude/claude_desktop_config.json
Linux： ~/.config/Claude/claude_desktop_config.json
工具
监控
log-query ：跟踪对话模式
高：常见互动（未记录）
中等：不寻常的模式（已记录）
低：关键事件（优先记录）
询问
位于与安装相关的data/varlog.db 。
