WHAT IT DOES

What weighted_mean does on UnClick

AI agents use weighted_mean to create or update resources in UnClick, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your UnClick environment.

Parameter	Type	Required	Description
`values`	array	Yes	Array of numeric values.
`weights`	array	—	Optional weights (same length as values).

Parameters from the server's own tool schema.

RISK

Why weighted_mean is rated Medium

An AI agent can call weighted_mean faster than any human can review: one bad instruction and it creates or modifies resources in UnClick by the hundred, each call as confident as the last.

RECOMMENDED RULE

The rule that runs weighted_mean safely

PolicyLayer is an MCP gateway: it sits between your AI agents and UnClick, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For weighted_mean, this is the rule to start with:

weighted_mean Rate-limited

weighted_mean stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

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

FAQ

Questions about weighted_mean

What does the weighted_mean tool do? +

Compute weighted, arithmetic, geometric, and harmonic means of a set of values. It is categorised as a Write tool in the UnClick MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

What parameters does weighted_mean accept? +

weighted_mean accepts 2 parameters: values, weights. Required: values. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on weighted_mean? +

Register the UnClick MCP server in PolicyLayer and add a rule for weighted_mean: 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 UnClick. Nothing to install.

What risk level is weighted_mean? +

weighted_mean is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit weighted_mean? +

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

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

weighted_mean is provided by the UnClick MCP server (@unclick/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
