Description

Penumbra MCP Server is a TypeScript-based Model Context Protocol (MCP) server that provides standardized tools for querying and interacting with the Penumbra blockchain. It offers endpoints for validator set details, chain status, transaction lookups, DEX batch auction state, and governance proposals, with mock implementations for development and plans to integrate with Penumbra client libraries. The project includes environment-driven configuration and an integration example for Claude Desktop to make it easy to attach to agent toolchains. It is designed to respect Penumbra's privacy-preserving features like shielded transactions and sealed-bid DEX auctions.
