AI agents call get_current_block_number 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 purely queries current blockchain state (block number) and returns read-only information. It has no capability to execute transactions, modify data, delete information, or commit financial obligations. The compact output format further indicates a simple data retrieval operation with minimal blast radius if misused by an AI agent.
From the tool's definition Tool description states 'Get current block number only (compact output)' - retrieves blockchain data with no side effects or ability to modify state
Attacks that exploit this kind of access
Get current block number only (compact output). 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_current_block_number: 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_current_block_number 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_current_block_number 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_current_block_number. 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_current_block_number 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.
