Filter and parse blockchain blocks in Windsurf

Cascade uses `filter_blocks` to scan chain history based on your specific SQL-like criteria. It pulls exact blocks without you writing a single line of manual query logic. You define the time range or transaction threshold. Windsurf executes the request and brings the raw data straight into your editor context.

Track transaction flows using this MCP Server

Use `filter_transactions` to isolate fee structures or specific activity spikes. Cascade handles the heavy lifting by passing your parameters to the API and returning the filtered results. This MCP Server lets you debug smart contract interactions or monitor network traffic. You see the transaction list in your chat panel immediately after the agent runs the tool.

Automated wallet and address inspection

Cascade can call `get_address` or `get_xpub` to pull balances and UTXO sets for any wallet. It reads the data and maps it to your current project files. Validating addresses or checking token balances takes seconds. The agent verifies the data against the live chain and reports discrepancies before you commit code.
