WHAT IT DOES

What lcm does on TinyFn

AI agents call lcm 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`	integer	Yes	First number
`b`	integer	Yes	Second number

Parameters from the server's own tool schema.

RISK

Why lcm is rated Low

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

RECOMMENDED RULE

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

lcm Allowed

lcm 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": {
    "lcm": {}
  }
}

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 lcm call is checked against it from then on.

FAQ

Questions about lcm

What does the lcm tool do? +

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.

What parameters does lcm accept? +

lcm 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 lcm? +

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.

What risk level is lcm? +

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

Can I rate-limit lcm? +

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.

How do I block lcm completely? +

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.

What MCP server provides lcm? +

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.
