MCP Log Analyzer

🔍 MCP Log Analyzer

The MCP Log Analyzer is an AI-powered Streamlit app designed to analyze system log files, identify errors and warnings, and recommend fixes. It uses FastMCP, LangGraph ReAct agents, and Anthropic Claude LLM to build a powerful multi-agent system.

Create Virtual Environment

python -m venv .venv ..venv\Scripts\activate

Install Dependencies

pip install -r requirements.txt

If requirements.txt doesn't exist, here are the needed packages:

pip install streamlit langchain langgraph langchain-anthropic anyio nest_asyncio pip install mcp langchain-mcp-adapters

🧪 Run MCP Tool Server

python analyzer.py

🧠 Run the Streamlit Client App

streamlit run streamlit_ui.py

🧾 Sample mcp_config_2.json

{ "mcpServers": { "LogAnalyzer": { "command": "{Your-directory}\uv.EXE", "args": [ "run", "--with", "mcp[cli]", "mcp", "run", "{Your-directory}\analyzer.py" ] } } }

📦 Log File Format

Uploaded logs should be a list of JSON objects like:

[ { "timestamp": "2025-07-26T12:30:01Z", "level": "ERROR", "component": "DataProcessor", "message": "NullPointerException in AuthService", "stack_trace": "java.lang.NullPointerException..." }, ... ]

📌 Notes

Claude API key is required in streamlit_client.py. Replace 'Your-API-Key' with your actual key.

If using TCP transport instead of stdio (recommended on Windows), modify the server and client configs accordingly.

You can customize or add new tools in analyzer.py and expose them via @mcp.tool().
