What floor does on TinyFn
AI agents call floor 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 |
|---|---|---|---|
number | number | Yes | Number to floor |
Parameters from the server's own tool schema.
Why floor is rated Low
This is a deterministic mathematical function that takes a numeric input and returns a rounded value. It performs no I/O, creates no data, executes no external commands, and cannot be misused to cause harm. It is a simple read-only computation, consistent with the server's stated purpose of providing 500+ deterministic tools for math operations.
From the tool's definition Tool name 'floor' and description 'Round down to nearest integer' indicate a pure mathematical computation with no side effects, no data modification, no external operations.
Attacks that exploit this kind of access
The rule that runs floor 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 floor, this is the rule to start with:
floor 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 floor call is checked against it from then on.
Questions about floor
Round down to nearest integer. It is categorised as a Read tool in the TinyFn MCP Server, which means it retrieves data without modifying state.
floor accepts 1 parameter: number. Required: number. 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 floor: 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.
floor 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 floor 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 floor. 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.
floor 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.
