time-mcp

A minimal agentic AI system that answers time-related and general questions using a tool-augmented LLM pipeline.

Features

• Flask API: Provides the current timestamp.

• MCP Agent Server: Reasoning agent that detects user intent, calls tools (like the time API), engineers prompts, and interacts with an LLM via OpenRouter (OpenAI-compatible API).

• Streamlit UI: Simple chat interface to talk to the AI agent.

Related MCP server: MCP-RAG

Setup

1. Clone and Install Dependencies

2. Environment Variable

Set your OpenRouter API key (get one from https://openrouter.ai):

3. Run the Servers

Open three terminals (or use background processes):

Terminal 1: Flask Time API

Terminal 2: MCP Agent Server

Terminal 3: Streamlit UI

The Streamlit UI will open in your browser (default: http://localhost:8501)

Usage

• Ask the agent any question in the Streamlit UI.

• If you ask about the time (e.g., "What is the time?"), the agent will call the Flask API, fetch the current time, and craft a beautiful, natural response using the LLM.

• For other questions, the agent will answer using the LLM only.

Architecture

• The MCP agent detects intent, calls tools as needed, engineers prompts, and sends them to the LLM.

• Easily extensible to add more tools (just add to the MCPAgent class).

Customization

• Add more tools: Implement new methods in MCPAgent and update self.tools.

• Improve intent detection: Extend detect_intent() in MCPAgent.

• Change LLM model: Update the model field in call_llm().

Requirements

• Python 3.7+

• See requirements.txt for dependencies.

Credits

• Built using Flask, Streamlit, OpenRouter, and Python.

• Inspired by agentic LLM design patterns.
