AI agents call clamp 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 |
|---|---|---|---|
number | number | Yes | The number to clamp |
maximum | number | Yes | Maximum value |
minimum | number | Yes | Minimum value |
Parameters from the server's own tool schema.
The clamp function is a deterministic mathematical utility that constrains a value between minimum and maximum bounds. It performs a read-only computation on its inputs and produces output without creating, modifying, deleting, executing external code, or committing financial transactions.
From the tool's definition Tool name is 'clamp' and description states it 'Clamp a number within a range.' This is a pure mathematical operation that reads/transforms a number parameter and returns a constrained value with no side effects, modifications to external state, or…
Attacks that exploit this kind of access
Clamp a number within a range. It is categorised as a Read tool in the TinyFn MCP Server, which means it retrieves data without modifying state.
clamp accepts 3 parameters: number, maximum, minimum. Required: number, maximum, minimum. 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 clamp: 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.
clamp 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 clamp 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 clamp. 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.
clamp 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.
clamp 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.
