What weighted_average does on Gateway
AI agents call weighted_average to retrieve information from Gateway 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 |
|---|---|---|---|
values | array | Yes | Numeric values |
weights | array | Yes | Weights, same length as values |
Parameters from the server's own tool schema.
Why weighted_average is rated Low
This is a mathematical calculator that takes values and weights as input and returns computed statistics (weighted mean, sum of weights, contribution analysis). It performs read-only computation with no ability to modify, delete, execute arbitrary code, or interact with external systems. The blast radius of misuse is minimal—worst case is incorrect calculation of a weighted average.
From the tool's definition Tool name 'weighted_average' and description 'Weighted Average Calculator — Weighted mean, sum of weights, and effective contribution of each value' indicate a pure calculation function that retrieves/computes statistics on provided input data with no side…

The rule that runs weighted_average safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Gateway, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For weighted_average, this is the rule to start with:
weighted_average is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Gateway, apply this rule, and every weighted_average call is checked against it from then on.
Questions about weighted_average
Weighted Average Calculator — Weighted mean, sum of weights, and effective contribution of each value. It is categorised as a Read tool in the Gateway MCP Server, which means it retrieves data without modifying state.
weighted_average accepts 2 parameters: values, weights. Required: values, weights. The full parameter table on this page comes from the server's own tool schema.
Register the Gateway MCP server in PolicyLayer and add a rule for weighted_average: 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 Gateway. Nothing to install.
weighted_average 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 weighted_average 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 weighted_average. 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.
weighted_average is provided by the Gateway MCP server (https://wingmanprotocol.com/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
