MCP Variance Log

MCP Variance Log is an MCP server that detects statistical variations and unusual interaction patterns in conversation structures and stores those events directly in a local SQLite database. Designed for developers, researchers, and system administrators running AI agents in environments like Claude Desktop, it operates as an unobtrusive auditing and observation layer. During dialogue, the server categorizes events into probability bands such as common, unusual, or critical. Whenever an interaction falls into a medium or low probability threshold, such as anomalous factual claims or sudden conversational shifts, the server records detailed metadata including user identifiers, session markers, context summaries, and analytical reasoning. In addition to continuous anomaly logging, MCP Variance Log exposes database querying tools that allow users to inspect historical logs, run custom SQL commands, examine table structures, and extract audit records directly through natural language prompts within their chosen Model Context Protocol client.

How to install and configure MCP Variance Log

1. Ensure Python 3.10 or higher, SQLite3, and UV are installed on your machine. 2. Clone the repository and install dependencies: bash git clone https://github.com/truaxki/mcp-variance-log.git cd mcp-variance-log uv pip install -e . 3. Add the server to your Claude Desktop configuration file (claude_desktop_config.json): json { "mcpServers": { "mcp-variance-log": { "command": "uv", "args": [ "--directory", "PATH_TO_REPO/mcp-variance-log", "run", "mcp-variance-log" ] } } } 4. Restart Claude Desktop to start using the tools.

What you can do with MCP Variance Log

• Flagging and recording anomalous user assertions or improbable factual claims during interactive AI sessions for audit review. - Querying logged conversation irregularities using natural language text-to-SQL commands directly from Claude Desktop. - Analyzing communication patterns by categorizing interactions into distinct high, medium, and low statistical probability classes. - Managing local auditing storage by inspecting table structures, viewing filtered history, and executing custom SQL write operations.
