Estimate the monthly SmoothSend credit cost for a dApp based on transaction volume and type. Returns per-transaction fee and monthly total.
AI agents call estimate_credits to retrieve information from SmoothSend MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool calculates and retrieves estimated credit costs based on input parameters (transaction volume and type). It is informational only—providing forecasts of what credits would cost, not actually charging, deducting, or committing funds. No transactions are executed, no data is modified, and no financial obligation is incurred. This is a Read operation: data retrieval with no side effects.
From the tool's definition Tool performs estimation and returns cost projections; does not execute transactions, modify data, or commit financial obligations. Description states it 'Estimate[s]' and 'Returns' values, indicating a query/calculation operation with no side effects.

Register the SmoothSend MCP Server MCP server in PolicyLayer and add a rule for estimate_credits: 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 SmoothSend MCP Server. Nothing to install.
estimate_credits 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 estimate_credits 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 estimate_credits. 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.
estimate_credits is provided by the SmoothSend MCP Server MCP server (smoothsend/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
estimate_credits is one line of SmoothSend MCP Server's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
