Shared Multi-Chain Tooling via MCP Server Config

The `get_blockchain_stats` tool delivers real-time network metrics directly to your VS Code Copilot agent. By committing the Blockchair configuration to your repo, your entire engineering team gets instant access to live on-chain metrics in VS Code. Developers can run `validate_address` inside Copilot Chat to check address formats across different chains. This shared VS Code Copilot environment keeps everyone on the same page, preventing bad address formats from slipping into your codebase.

Audit Smart Contracts and Tokens in Chat

The `get_contract_calls` tool retrieves internal transactions for Ethereum contracts directly into your VS Code Copilot panel. You can inspect complex execution paths during code reviews without switching to an external browser tab. Combine this with `get_erc20_token_address` to verify token balances on specific accounts inside VS Code. Your VS Code Copilot agent analyzes the returned JSON payload from this MCP Server and explains the token distribution or contract state right inside your editor.

SQL-Style On-Chain Data Filtering

The `filter_transactions` tool lets your team query blockchain transactions using SQL-like filters directly inside VS Code Copilot. Instead of writing custom API scripts, you ask VS Code Copilot to find transactions matching specific fee ranges or block numbers. Pair this with `filter_blocks` to isolate blocks that fit your exact parameters within VS Code Copilot. Copilot runs the Blockchair query, grabs the block data, and helps you write the parser logic in your local files.
