AI agents call lcm 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.
| Parameter | Type | Required | Description |
|---|---|---|---|
a | integer | Yes | First number |
b | integer | Yes | Second number |
Parameters from the server's own tool schema.
This is a deterministic mathematical utility that only retrieves/computes a value based on input arguments. It has no capability to modify data, execute code, delete resources, or affect external systems. It belongs in the Read category as a data retrieval/computation tool, with low severity because misuse poses no operational or security risk.
From the tool's definition Tool description states 'Calculate the least common multiple' — a pure mathematical computation with no side effects, data modification, or external operations.
Attacks that exploit this kind of access
Calculate the least common multiple. It is categorised as a Read tool in the TinyFn MCP Server, which means it retrieves data without modifying state.
lcm accepts 2 parameters: a, b. Required: a, b. 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 lcm: 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.
lcm 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 lcm 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 lcm. 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.
lcm 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.
lcm 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.
