What estimate_hash_time does on TinyFn
AI agents call estimate_hash_time to retrieve information from TinyFn without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
password | string | Yes | Password to estimate crack time for |
Parameters from the server's own tool schema.
Why estimate_hash_time is rated Low
This tool retrieves or computes derived data (time estimate) without side effects. It is deterministic analysis that helps inform security decisions but does not itself perform cracking, execute commands, or alter any system state. The low severity reflects minimal blast radius—misuse would only provide incorrect estimates, not compromise security directly.
From the tool's definition The tool 'estimate_hash_time' is described as estimating time to crack a password—it performs a calculation or lookup based on input parameters and returns an estimate. It does not modify, execute code, delete data, or move money.

The rule that runs estimate_hash_time safely
PolicyLayer is an MCP gateway: it sits between your AI agents and TinyFn, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For estimate_hash_time, this is the rule to start with:
estimate_hash_time is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect TinyFn, apply this rule, and every estimate_hash_time call is checked against it from then on.
Questions about estimate_hash_time
Estimate time to crack a password using brute force. It is categorised as a Read tool in the TinyFn MCP Server, which means it retrieves data without modifying state.
estimate_hash_time accepts 1 parameter: password. Required: password. The full parameter table on this page comes from the server's own tool schema.
Register the TinyFn MCP server in PolicyLayer and add a rule for estimate_hash_time: 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 TinyFn. Nothing to install.
estimate_hash_time 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_hash_time 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_hash_time. 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_hash_time is provided by the TinyFn MCP server (https://api.tinyfn.io/mcp/all/). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
