AI agents call get_block to retrieve information from Tron without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves immutable historical blockchain data. It has no side effects, cannot modify state, execute code, or commit financial transactions. The minimal blast radius (an AI agent querying block data) poses negligible security risk. Confidence is high because the intent is unambiguous from both name and description.
From the tool's definition Tool name 'get_block' with description 'Get block information' indicates a read-only query operation that retrieves blockchain block data without modification or execution of transactions.
Attacks that exploit this kind of access
Get block information. It is categorised as a Read tool in the Tron MCP Server, which means it retrieves data without modifying state.
Register the Tron MCP server in PolicyLayer and add a rule for get_block: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Tron. Nothing to install.
get_block is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_block rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for get_block. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
get_block is provided by the Tron MCP server (netts-official/tron_mcp_server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
