Hats Protocol

Hats Protocol MCP server by Dennison Bertram that provides complete organizational role management through the Hats Protocol across multiple blockchain networks including Ethereum, Polygon, Arbitrum, Optimism, Base, and Gnosis Chain. The implementation combines the Hats Protocol SDK with subgraph queries to offer hat creation, minting, burning, and transfer operations, plus permission checking, organizational structure visualization, and guided workflows through built-in prompts for common scenarios like organization setup and role auditing. Features external transaction signing for hardware wallet compatibility, multi-chain RPC management with fallback endpoints, and intelligent caching, making it valuable for DAOs managing hierarchical role structures, governance systems requiring on-chain permission verification, and organizations transitioning to decentralized role-based access control with blockchain-native identity management.
