Monitor recent token transfer activity, whale movements, and unusual trading
AI agents call token_monitor to retrieve information from Hedera Toolbox without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and analyzes blockchain token data (transfers, whale movements, trading patterns) without creating, modifying, deleting, or executing any operations. It is a pure data query/retrieval function.
From the tool's definition Tool description states 'Monitor recent token transfer activity, whale movements, and unusual trading' — all read-only observation activities with no modification, deletion, or execution of code.

Register the Hedera Toolbox MCP server in PolicyLayer and add a rule for token_monitor: 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 Hedera Toolbox. Nothing to install.
token_monitor 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 token_monitor 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 token_monitor. 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.
token_monitor is provided by the Hedera Toolbox MCP server (mountainmystic/hederatoolbox). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
