Get information about latest blocks
AI agents call getLatestBlocks to retrieve information from Plasma Testnet MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read-only query that retrieves blockchain block data. It has no side effects, cannot trigger transactions, execute code, or modify state. The blast radius of misuse is minimal since an AI agent querying block information cannot cause financial loss, delete data, or trigger unintended operations. It is purely informational.
From the tool's definition The tool name is 'getLatestBlocks' and the description states it gets 'information about latest blocks' — a retrieval operation with no modification, execution, or financial implications.
