WHAT IT DOES

What min_value does on TinyFn

AI agents call min_value 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
`numbers`	string	Yes	Comma-separated numbers

Parameters from the server's own tool schema.

RISK

Why min_value is rated Low

This tool performs a read-only computation on data (finding the minimum value) with no side effects, no data modification, no execution of arbitrary code, and no irreversible actions. It fits cleanly into the Read category.

From the tool's definition Tool name 'min_value' with description 'Find minimum value' is a deterministic mathematical operation that retrieves or queries a result from input data without modifying, deleting, or executing external operations.

RECOMMENDED RULE

The rule that runs min_value 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 min_value, this is the rule to start with:

min_value Allowed

min_value is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "min_value": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect TinyFn, apply this rule, and every min_value call is checked against it from then on.

FAQ

Questions about min_value

What does the min_value tool do? +

Find minimum value. It is categorised as a Read tool in the TinyFn MCP Server, which means it retrieves data without modifying state.

What parameters does min_value accept? +

min_value accepts 1 parameter: numbers. Required: numbers. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on min_value? +

Register the TinyFn MCP server in PolicyLayer and add a rule for min_value: 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.

What risk level is min_value? +

min_value is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit min_value? +

Yes. Add a rate_limit block to the min_value 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.

How do I block min_value completely? +

Set action: deny in the PolicyLayer policy for min_value. 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.

What MCP server provides min_value? +

min_value 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.
