-# Topcoder MCP Agent
+# Topcoder MCP Agent v2.0
 
-A configurable MCP (Model Context Protocol) agent for Topcoder that can work with different LLM providers.
+A **Model Context Protocol (MCP) compliant agent** for interacting with Topcoder APIs. This project connects to Topcoder's MCP server to provide AI-powered assistance for challenges, skills, member data, and more through a clean Gradio web interface.
 
-## Configuration
+> **Note**: This v2.0 maintains the exact logic and behavior of v1.0 while implementing a modern, maintainable architecture.
 
-### Environment Variables
+## ✨ Features
 
-Create a `.env` file in the project root with the following variables:
+- 🤖 **AI-Powered Assistant**: Natural language interface for Topcoder data
+- 🔌 **MCP Integration**: Connects to Topcoder's official MCP server
+- 🎯 **Tool Discovery**: Automatically catalogs available tools and resources
+- 📊 **Smart Filtering**: Intelligently filters API responses for relevance
+- 🌐 **Web Interface**: Clean Gradio-based UI for easy interaction
+- ⚡ **Real-time**: Live connection to Topcoder APIs
+- 💬 **Conversation History**: Maintains context across multiple interactions
+- 🧠 **Context-Aware**: LLM considers previous conversation when making decisions
 
-```bash
-# LLM Configuration
-HF_TOKEN=your_huggingface_token
-HF_MODEL=Qwen/Qwen2.5-7B-Instruct:together
-LLM_API_URL=https://router.huggingface.co/v1/chat/completions
-LLM_TEMPERATURE=0.8
+## 🚀 Quick Start
 
-# MCP Configuration
-MCP_SERVER_URL=https://api.topcoder-dev.com/v6/mcp/mcp
-MCP_TOKEN=your_mcp_token
+### 1. Installation
 
-# API Authentication Configuration
-EXCLUDE_AUTH_REQUIRED_ENDPOINTS=true
-EXCLUDE_401_RESPONSES=true
-STRICT_AUTH_FILTERING=false
-```
+```bash
+# Clone the repository
+git clone <repository-url>
+cd topcoder-mcp-agent
 
-### Authentication Filtering Options
+# Install dependencies
+pip install -r requirements.txt
 
-The system includes configurable authentication filtering to exclude endpoints that require authentication:
+# Install the package in development mode
+pip install -e .
+```
 
-- **`EXCLUDE_AUTH_REQUIRED_ENDPOINTS`** (default: `true`): Enable/disable authentication filtering
-- **`EXCLUDE_401_RESPONSES`** (default: `true`): Filter out endpoints that have 401 responses in documentation
-- **`STRICT_AUTH_FILTERING`** (default: `false`): More aggressive filtering based on authentication keywords in descriptions
+### 2. Configuration
 
-This ensures that only publicly accessible APIs are included in the compact specs when no authentication is configured.
+Create a `.env` file in the project root:
 
-## Example .env file
-```
+```bash
+# LLM Configuration (Required)
 HF_TOKEN=your_huggingface_token_here
 HF_MODEL=Qwen/Qwen2.5-7B-Instruct:together
-LLM_API_URL=https://router.huggingface.co/v1/chat/completions
-LLM_TEMPERATURE=0.8
-MCP_BASE_URL=https://api.topcoder-dev.com/v6/mcp/mcp
-MCP_SERVER_URL=https://api.topcoder-dev.com/v6/mcp/mcp
-MCP_TOKEN=your_mcp_token_here
-```
 
-## Usage
+# MCP Configuration (Optional - defaults provided)
+MCP_BASE_URL=https://api.topcoder-dev.com/v6/mcp/mcp
 
-1. Run the setup script to create a default `.env` file:
-```bash
-python setup.py
+# Conversation History (Optional - defaults provided)
+CONVERSATION_ENABLE_HISTORY=true
+CONVERSATION_MAX_HISTORY_LENGTH=20
+CONVERSATION_MAX_TOKENS=4000
 ```
 
-2. Install dependencies:
-```bash
-pip install -r requirements.txt
-```
+**Get your HuggingFace token**: Visit [HuggingFace Settings](https://huggingface.co/settings/tokens) to create a free token.
 
-3. Update the `.env` file with your actual API tokens and URLs
+### 3. Launch
 
-4. Run the application:
 ```bash
-python -m app.main
-```
-
-The application will automatically:
-- Connect to the MCP server
-- Discover available tools and resources
-- Catalog tool schemas and analyze API documentation
-- Store structured data in the `mcp_catalog/` directory
-
-### Using Cataloged Data
-
-The cataloged data can be accessed programmatically:
+# Using the entry point command
+topcoder-agent
 
-```python
-from app.mcp.catalog_utils import CatalogUtils
-
-utils = CatalogUtils()
-
-# Get tool schema
-tool_schema = utils.get_tool_schema("query-tc-challenges")
+# Or run directly
+python3 src/main.py
+```
 
-# Format a tool request
-request = utils.format_tool_request("query-tc-challenges", {
-    "status": "Active",
-    "perPage": 10
-})
+The web interface will be available at `http://127.0.0.1:7860`
 
-# Find API endpoints
-endpoint = utils.find_api_endpoint("Challenges V6 API Swagger", "/challenges", "GET")

-The system also generates compact API specs that are much smaller and only include working tools/resources:
+## 🔧 How It Works
 
-```python
-from app.mcp.compact_utils import CompactSpecsUtils
+### 1. MCP Connection & Discovery
+```
+[Agent] → [MCP Server] → [Topcoder APIs]
+   ↓
+[Tool/Resource Catalog] → [Compact Specs Generation]
+```
 
-utils = CompactSpecsUtils()
+The agent connects to Topcoder's MCP server and discovers available:
+- **Tools**: `query-tc-challenges`, `query-tc-skills`
+- **Resources**: Challenge API, Member API, Identity API, Review API
 
-# Get working tools
-working_tools = utils.get_working_tools()
+### 2. Conversation Flow with History
+```
+User Input → Session Manager → Conversation History → LLM Decision → Tool Execution → Response → History Update
+```
 
-# Format a tool request using compact specs
-request = utils.format_tool_request("query-tc-challenges", {
-    "status": "Active",
-    "perPage": 10
-})
+The agent now maintains conversation context:
+- **Session Management**: Each conversation gets a unique session
+- **History Storage**: Recent messages are stored with configurable limits
+- **Context-Aware Decisions**: LLM considers previous interactions
+- **Sliding Window**: Older messages are automatically removed
 
-# Get resource endpoints
-endpoints = utils.get_resource_endpoints("Challenges_V6_API_Swagger")
-```
+## 💡 Usage Examples
 
-### Dynamic Tool Execution
-
-The agent now uses compact specs for dynamic tool execution instead of hardcoded prompts:
-
-```python
-from app.agent.prompt_engine import PromptBuilder
-from app.agent.tool_executor import ToolExecutor
-
-# Dynamic prompt generation
-prompt_builder = PromptBuilder()
-prompt = prompt_builder.build_tool_decision_prompt("Show me active challenges")
-
-# Dynamic tool execution
-tool_executor = ToolExecutor()
-available_tools = tool_executor.get_available_tools()  # ['query-tc-skills', 'query-tc-challenges']
-available_resources = tool_executor.get_available_resources()  # ['Challenges_V6_API_Swagger', 'Member_V6_API_Swagger', 'Identity_V6_API_Swagger']
-
-# Format resource requests
-resource_request = tool_executor.compact_utils.format_resource_request(
-    "Challenges_V6_API_Swagger", 
-    "/challenges", 
-    "GET", 
-    {"status": "Active"}
-)
-
-# Make direct API calls with parameter substitution
-result = await tool_executor.compact_utils.make_direct_api_call(
-    "Member_V6_API_Swagger",
-    "/members/abhishekrn",  # Path parameters are substituted
-    "GET"
-)
-
-# Or with query parameters (using hardcoded base URL)
-result = await tool_executor.compact_utils.make_direct_api_call(
-    "Challenges_V6_API_Swagger",
-    "/challenges",
-    "GET",
-    {"status": "Active", "track": "Development", "totalPrizesFrom": "1000", "sortBy": "overview.totalPrizes", "sortOrder": "desc", "perPage": "20"}
-)
-
-**Key Improvements:**
-- **Simplified Prompts**: Dynamic prompts are concise and focused
-- **Parameter Cleaning**: Empty parameters are automatically filtered out
-- **Better Tool Selection**: Clear usage instructions for each tool
-- **Parameter Extraction**: Automatic extraction when parameters are missing
-- **Validation**: Tools are validated against compact specs before execution
-- **Resource Support**: Can now execute both tools and API resources
-- **Dynamic Endpoints**: Resources include key endpoints for API calls
-- **Direct API Calls**: Resources can make direct API calls using extracted base URLs
-- **Base URL Extraction**: Automatically extracts API base URLs from OpenAPI documents
-- **Version Handling**: Properly handles API versions from swagger documents
-- **Correct URL Format**: Uses `https://api.topcoder.com/v5/` format for all Topcoder APIs
-- **Parameter Extraction**: Automatically extracts parameters from user queries for both tools and resources
-- **Path Substitution**: Correctly substitutes path parameters (e.g., `{handle}` → `abhishekrn`) in API endpoints
-
-## Features
-
-- Generic LLM client that can work with different models
-- Configurable through environment variables
-- MCP integration for Topcoder API with proper session management
-- Web UI interface using Gradio
-- Tool-based architecture for handling different types of requests
-- Automatic MCP server connection and tool/resource discovery
-- **Intelligent cataloging system** that:
-  - Stores tool schemas with input/output structures
-  - Analyzes API documentation (Swagger/OpenAPI) to extract endpoints and schemas
-  - Provides utilities for formatting tool requests and finding API endpoints
-  - Maintains structured data for easy programmatic access
-  - **Compact API specs generation** that:
-    - Tests functionality of tools and resources
-    - Filters out non-working APIs
-    - Generates concise specs similar to `api_specs.py`
-    - Reduces large catalogs to manageable size
-- **Hardcoded base URLs** for reliable API access:
-    - Uses `https://api.topcoder.com/v5/` for all Topcoder APIs
-    - Supports all parameters from compact API specs
-    - Ensures consistent API access without authentication issues
