AI agents call range_to_cidr to retrieve information from TinyFn without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
end_ip | string | Yes | End IP address |
start_ip | string | Yes | Start IP address |
Parameters from the server's own tool schema.
This is a deterministic conversion utility that takes an IP range as input and outputs CIDR notation. It retrieves no data, modifies nothing, executes no code, and has no irreversible effects. It fits the Read category as a data transformation/query tool. Severity is low because misuse would only affect the output format, not cause harm to systems or data.
From the tool's definition Tool name 'range_to_cidr' and description 'Convert an IP range to CIDR notation' indicate a pure data transformation/conversion operation with no side effects, no data modification, no execution of external code, and no destructive actions.
Attacks that exploit this kind of access
Convert an IP range to CIDR notation. It is categorised as a Read tool in the TinyFn MCP Server, which means it retrieves data without modifying state.
range_to_cidr accepts 2 parameters: end_ip, start_ip. Required: end_ip, start_ip. 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 range_to_cidr: 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.
range_to_cidr 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 range_to_cidr 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 range_to_cidr. 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.
range_to_cidr 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.
range_to_cidr is one line of TinyFn's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
