What netmask_to_cidr does on TinyFn
AI agents call netmask_to_cidr 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 |
|---|---|---|---|
netmask | string | Yes | Netmask (e.g., 255.255.255.0) |
Parameters from the server's own tool schema.
Why netmask_to_cidr is rated Low
This is a deterministic conversion utility that takes a subnet mask as input and outputs its CIDR notation equivalent. It performs no data modification, deletion, external operations, or financial actions. It is purely a read-like operation that transforms one data format to another, consistent with the server's purpose of providing 500+ deterministic tools for math, conversion, and validation.
From the tool's definition Tool name 'netmask_to_cidr' and description 'Convert subnet mask to CIDR prefix length' indicate a data transformation/conversion operation with no side effects.
Attacks that exploit this kind of access
The rule that runs netmask_to_cidr 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 netmask_to_cidr, this is the rule to start with:
netmask_to_cidr 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 netmask_to_cidr call is checked against it from then on.
Questions about netmask_to_cidr
Convert subnet mask to CIDR prefix length. It is categorised as a Read tool in the TinyFn MCP Server, which means it retrieves data without modifying state.
netmask_to_cidr accepts 1 parameter: netmask. Required: netmask. 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 netmask_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.
netmask_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 netmask_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 netmask_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.
netmask_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.
