# Substrate Blockchain

> Use this tool when you need to interact with Substrate blockchain operations, such as querying account balances or submitting transactions, directly from an AI assistant. It solves problems of context switching and provides a Rust-based interface for accessing blockchain data like events, blocks, and extrinsics. The tool is ideal for blockchain developers and users who require dynamic operations across different pallets, with optional transaction signing capabilities.

## Description

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.
