Calculate the Nimiq PoS supply at a given time. Returns the calculated supply for the specified timestamp and network.
AI agents call calculate_nimiq_supply_at to retrieve information from Nimiq MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a deterministic calculation based on input parameters (timestamp and network) and returns information without creating, modifying, deleting, or executing any operations. It is a read-only query tool similar to other sibling tools like get_nimiq_balance and get_nimiq_price that retrieve blockchain state information.
From the tool's definition Tool description states it 'Calculate[s] the Nimiq PoS supply at a given time. Returns the calculated supply' — a pure calculation/query operation with no side effects, data modification, or state changes.
Attacks that exploit this kind of access
Calculate the Nimiq PoS supply at a given time. Returns the calculated supply for the specified timestamp and network. It is categorised as a Read tool in the Nimiq MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Nimiq MCP Server MCP server in PolicyLayer and add a rule for calculate_nimiq_supply_at: 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 Nimiq MCP Server. Nothing to install.
calculate_nimiq_supply_at 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 calculate_nimiq_supply_at 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 calculate_nimiq_supply_at. 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.
calculate_nimiq_supply_at is provided by the Nimiq MCP Server MCP server (onmax/nimiq-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
