AI agents call is_odd 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.

number | integer | Yes | The number to check |
Parameters from the server's own tool schema.
This is a deterministic mathematical utility that only reads and evaluates an input number. It returns a boolean result without creating, modifying, deleting data, executing code, or triggering external operations. The tool has minimal blast radius even if misused by an AI agent.
From the tool's definition Tool name 'is_odd' and description 'Check if a number is odd' indicate a pure query operation that retrieves or determines a boolean property of a number with no side effects, no data modification, and no external operations triggered.
Attacks that exploit this kind of access
Check if a number is odd. It is categorised as a Read tool in the TinyFn MCP Server, which means it retrieves data without modifying state.
is_odd 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 is_odd: 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.
is_odd 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 is_odd 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 is_odd. 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.
is_odd 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.
is_odd 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.
