What setops_calculate does on UnClick
AI agents invoke setops_calculate to trigger actions in UnClick. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
| Parameter | Type | Required | Description |
|---|---|---|---|
set_a | array | Yes | First set (array of values). |
set_b | array | Yes | Second set (array of values). |
Parameters from the server's own tool schema.
Why setops_calculate is rated High
The tool executes mathematical/logical computations on sets. It has no side effects on external data, but it runs a calculation/operation rather than simply retrieving stored data. Severity is low because the blast radius of misuse is minimal — it only computes results and returns them without modifying any persistent state.
From the tool's definition Perform set operations: union, intersection, difference, symmetric difference, subset/superset
Attacks that exploit this kind of access
The rule that runs setops_calculate 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 setops_calculate, this is the rule to start with:
setops_calculate stays usable, but rate-capped: a runaway agent can't fire it dozens of times 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 setops_calculate call is checked against it from then on.
Questions about setops_calculate
Perform set operations: union, intersection, difference, symmetric difference, subset/superset. It is categorised as a Execute tool in the UnClick MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
setops_calculate accepts 2 parameters: set_a, set_b. Required: set_a, set_b. The full parameter table on this page comes from the server's own tool schema.
Register the UnClick MCP server in PolicyLayer and add a rule for setops_calculate: 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.
setops_calculate is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the setops_calculate 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 setops_calculate. 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.
setops_calculate 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.
