Substrate Blockchain

The Substrate MCP server provides AI assistants with direct access to Substrate blockchain operations through a Rust implementation. Developed by Thomas Marches, this server exposes tools for querying account balances, accessing storage, submitting transactions, and retrieving blockchain data like events, blocks, and extrinsics. It leverages the subxt library for Substrate interaction and supports dynamic operations across different pallets, with optional transaction signing capabilities configured through environment variables. The implementation is particularly valuable for blockchain developers and users who need to interact with Substrate-based networks without switching contexts from their AI assistant.
