No API keys. Just Claude + persona data = magic. --- ## Environment Variables | Variable | Default | Description | |----------|---------|-------------| | `LEGENDS_MCP_DEBUG` | `false` | Enable debug logging | --- ## Important Disclaimers ``` NOT affiliated with, endorsed by, or representative of any real individual NOT financial, legal, or professional advice AI personas for EDUCATIONAL and ENTERTAINMENT purposes only Based on publicly available information, speeches, and writings Always do your own research (DYOR) ``` The views expressed by these AI personas are generated interpretations, not actual statements from the real people. --- ## Examples **💻 [Code Examples](./examples/)** - Runnable examples covering: - **Combined Workflow**: Using `get_legend_context` + `get_legend_insight` together - **Brainstorming Sessions**: Alternating insights from multiple legends - **Conflicting Advice**: Resolving disagreements between legends - **Multi-Turn Conversations**: Maintaining persona context across exchanges - **Blockchain Discussion**: Using Crypto Builder personas (CZ, Andre Cronje, Anatoly) Each example is executable (`chmod +x examples/*.js`) and includes: - Real-world scenarios (startup decisions, product design, DeFi protocols) - Error handling patterns - Performance optimization tips - Complete MCP tool coverage See **[examples/README.md](./examples/README.md)** for full catalog and usage guide. --- ## Documentation **📚 [Architecture Guide](./ARCHITECTURE.md)** - Learn how to: - Scale Legends MCP with custom user-defined personas - Maintain privacy-first design (zero external APIs) - Implement multi-tenancy and storage solutions - Extend the YAML schema for custom use cases --- ## Contributing Want to add a legend?
