For full functionality with real blockchain operations, install locally:
**Option 1: npm install (Auto-installs ZetaChain CLI + Foundry)**
\`\`\`bash
npm install -g @ExpertVagabond/universal-blockchain-mcp
# ZetaChain CLI + Foundry will be automatically installed!
# All 16 tools will work with real blockchain interaction
# Full smart contract development environment ready!
\`\`\`
**Option 2: Local MCP setup**
\`\`\`bash
git clone https://github.com/ExpertVagabond/universal-blockchain-mcp
cd universal-blockchain-mcp
npm install && npm run build
smithery install ./
\`\`\`
✅ **Automatic Setup**: ZetaChain CLI + Foundry install automatically
✅ **All 16 Tools**: Full blockchain functionality after local installation
✅ **Complete Dev Environment**: Ready for smart contract development
✅ **No Manual Setup**: Everything works out of the box
📚 **Smart Contract Development:**
- **Foundry**: Automatically installed (forge, cast, anvil, chisel)
- **ZetaChain CLI**: Automatically installed for blockchain interaction
- **ZetaChain Examples**: https://github.com/zeta-chain/example-contracts`;
