+
+## ๐ Security Best Practices
+
+### For Users
+
+#### ๐ API Key Management
+- **Never commit API keys** to version control
+- **Use environment variables** for API key storage
+- **Rotate API keys** regularly
+- **Use separate API keys** for different environments
+- **Monitor API key usage** for unusual activity
+
+#### ๐ Network Security
+- **Use HTTPS** for all external communications
+- **Validate SSL certificates** in production
+- **Implement rate limiting** to prevent abuse
+- **Monitor network traffic** for suspicious patterns
+
+#### ๐๏ธ Deployment Security
+- **Run with minimal privileges** (don't use root)
+- **Keep dependencies updated** regularly
+- **Use virtual environments** to isolate dependencies
+- **Monitor logs** for security events
+- **Implement proper logging** without exposing sensitive data
+
+#### ๐ Configuration Security
+- **Review configuration files** for sensitive data
+- **Use secure defaults** in production
+- **Validate all inputs** from external sources
+- **Sanitize outputs** to prevent information leakage
+
+### For Developers
+
+#### ๐ Secure Coding Practices
+- **Validate all inputs** at API boundaries
+- **Use parameterized queries** to prevent injection
+- **Implement proper error handling** without information disclosure
+- **Follow principle of least privilege** in code design
+- **Use secure random number generation** where applicable
+
+#### ๐งช Security Testing
+- **Include security tests** in your test suite
+- **Test error conditions** and edge cases
+- **Validate input sanitization** thoroughly
+- **Test authentication and authorization** mechanisms
+- **Review dependencies** for known vulnerabilities
+
+#### ๐ฆ Dependency Management
+- **Pin dependency versions** in requirements.txt
+- **Regularly update dependencies** to patch vulnerabilities
+- **Use dependency scanning tools** like `safety` or `bandit`
+- **Review new dependencies** before adding them
+- **Monitor security advisories** for used packages
+
+## ๐จ Known Security Considerations
+
+### Current Security Measures
+
+#### โ
Input Validation
+- All user inputs are validated and sanitized
+- Query parameters are properly escaped
+- API responses are structured to prevent injection
+
+#### โ
Error Handling
+- Errors don't expose sensitive system information
+- Stack traces are logged but not returned to users
+- Graceful degradation on failures
+
+#### โ
API Security
+- API keys are handled securely through environment variables
+- No API keys are logged or included in error messages
+- Rate limiting is implemented to prevent abuse
+
+#### โ
Dependencies
+- All dependencies are pinned to specific versions
+- Regular security audits of dependencies
+- Minimal dependency footprint to reduce attack surface
+
+### ๐ Areas for Ongoing Attention
+
+#### Network Communications
+- All external API calls use HTTPS
+- SSL certificate validation is enabled
+- Connection timeouts are configured appropriately
+
+#### Data Handling
+- No persistent storage of sensitive research data
+- Temporary data is properly cleaned up
+- Citations and URLs are validated before use
+
+#### Logging and Monitoring
+- Structured logging without sensitive data exposure
+- Appropriate log levels for different environments
+- No API keys or personal data in logs
+
+## ๐ง Security Tools and Automation
+
+### Recommended Tools
+
+#### For Development
+```bash
+# Install security scanning tools
+pip install bandit safety
+
+# Run security scans
+bandit -r server.py
+safety check
+```
+
+#### For Dependency Scanning
+```bash
+# Check for known vulnerabilities
+safety check requirements.txt
+
+# Audit Python packages
+pip-audit
+```
+
+#### For Code Analysis
+```bash
+# Static analysis for security issues
+bandit -r . -f json -o security-report.json
+
+# Check for secrets in code
+git-secrets --scan
+```
+
+### CI/CD Security
+
+We recommend implementing:
+- **Automated security scanning** in CI pipelines

+
+## Overview
+The Gemini Research Agent is an advanced Model Context Protocol (MCP) server that provides comprehensive research capabilities using Google's Gemini AI models. It offers tiered effort levels to balance thoroughness with efficiency.
+
+## Features
+- **Multi-tier Research**: Three effort levels (low, medium, high) with different search limits
+- **Intelligent Query Generation**: AI-powered search query creation and optimization
+- **Iterative Research**: Multiple research loops with reflection and gap analysis
+- **Citation Tracking**: Comprehensive source validation and citation management
+- **Error Handling**: Robust error handling with fallback mechanisms
+- **Async Performance**: Optimized for concurrent operations
+
+## Models Used
+- **Primary Research**: {RESEARCH_MODEL}
+- **Query Generation**: {QUERY_MODEL}
+- **Reflection**: {REFLECTION_MODEL}
+- **Final Answer**: {ANSWER_MODEL}
+
+## Available Tools
+
+### research_topic(topic, effort="medium")
+Conduct comprehensive research on any topic with configurable effort levels.
+
+**Parameters:**
+- `topic` (str): The research topic or question to investigate
+- `effort` (str): Research effort level - "low", "medium", or "high"
+
+**Returns:** Comprehensive research report with citations
+
+### get_effort_levels()
+Get detailed information about available research effort levels.
+
+**Returns:** Detailed breakdown of effort levels and capabilities
+
+### get_server_status()
+Get current server status and active research sessions.
+
+**Returns:** Server status and configuration information
+
+## Effort Levels
+
+| Level | Max Searches | Max Loops | Initial Queries | Best For |
+|--------|-------------|-----------|-----------------|----------|
+| Low | 10 | 1 | 2 | Quick facts, simple questions |
+| Medium | 100 | 3 | 4 | General research, balanced approach |
+| High | 1000 | 5 | 6 | Complex topics, comprehensive analysis |
+
+## Usage Examples
+
+### Basic Research
+```
+research_topic("artificial intelligence trends 2024")
+```
+
+### Low Effort Quick Research
+```
+research_topic("current weather in Paris", effort="low")
+```
+
+### High Effort Comprehensive Research
+```
+research_topic("impact of climate change on global agriculture", effort="high")
+```
+
+## Technical Details
+
+### Architecture
+- Built with FastMCP for optimal performance
+- Async/await pattern for concurrent operations
+- Comprehensive error handling and logging
+- State management for active research sessions
+
+### Citation System
+- URL validation and normalization
+- Source title extraction and cleaning
+- Citation formatting with markdown links
+- Duplicate source detection and removal
+
+### Rate Limiting
+- Effort-based search limits prevent API abuse
+- Exponential backoff for failed requests
+- Session tracking for resource management
+
+## Error Handling
+The server includes robust error handling:
+- API failures with automatic retries
+- Malformed query graceful degradation
+- Network timeout handling
+- Fallback responses for critical failures
+
+## Logging
+Comprehensive logging includes:
+- Research session tracking
+- Search query performance metrics
+- Error reporting and debugging information
+- Resource usage monitoring
