WHAT IT DOES

What compare does on TinyFn

AI agents call compare 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
`a`	number	Yes	First number
`b`	number	Yes	Second number

Parameters from the server's own tool schema.

RISK

Why compare is rated Low

This is a pure deterministic comparison function that performs a mathematical check between two inputs and returns a result (e.g., greater than, less than, equal). It cannot modify data, execute external code, delete anything, or cause financial impacts. It is a simple read operation matching the 'Read' category definition.

From the tool's definition Tool name 'compare' with description 'Compare two numbers' indicates a read-only operation that retrieves or queries the relationship between two numeric values with no side effects, modifications, or external operations.

RECOMMENDED RULE

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

compare Allowed

compare 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": {
    "compare": {}
  }
}

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 compare call is checked against it from then on.

FAQ

Questions about compare

What does the compare tool do? +

Compare two numbers (e.g., is 0.9 greater than 0.11?). It is categorised as a Read tool in the TinyFn MCP Server, which means it retrieves data without modifying state.

What parameters does compare accept? +

compare accepts 2 parameters: a, b. Required: a, b. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on compare? +

Register the TinyFn MCP server in PolicyLayer and add a rule for compare: 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 compare? +

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

Can I rate-limit compare? +

Yes. Add a rate_limit block to the compare 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 compare completely? +

Set action: deny in the PolicyLayer policy for compare. 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 compare? +

compare 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.
