What bounding_box does on TinyFn
AI agents call bounding_box 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 |
|---|---|---|---|
lat | number | Yes | Center latitude |
lon | number | Yes | Center longitude |
unit | string | — | Unit: km or mi |
radius | number | Yes | Radius |
Parameters from the server's own tool schema.
Why bounding_box is rated Low
This tool retrieves or computes geometric data without modifying any state, creating resources, executing code, or affecting external systems. It is a deterministic mathematical operation with no destructive or financial implications. Misuse by an AI agent poses minimal risk—the worst outcome is incorrect geometric calculations.
From the tool's definition The tool 'bounding_box' calculates a geometric bounding box around a point. The description indicates it performs a computation and returns a result with no side effects.
Attacks that exploit this kind of access
The rule that runs bounding_box 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 bounding_box, this is the rule to start with:
bounding_box 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 bounding_box call is checked against it from then on.
Questions about bounding_box
Calculate bounding box around a point. It is categorised as a Read tool in the TinyFn MCP Server, which means it retrieves data without modifying state.
bounding_box accepts 4 parameters: lat, lon, unit, radius. Required: lat, lon, radius. 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 bounding_box: 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.
bounding_box 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 bounding_box 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 bounding_box. 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.
bounding_box 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.
