What ternary_search does on UnClick
AI agents call ternary_search to retrieve information from UnClick 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 |
|---|---|---|---|
mode | string | — | Mode: search (default), max, or min |
array | array | Yes | Array of numbers |
target | number | — | Value to search for (search mode only) |
Parameters from the server's own tool schema.
Why ternary_search is rated Low
Ternary search is a classic read-only algorithm that locates a value in a sorted array or identifies extrema. It has no side effects, does not execute arbitrary code, does not modify data, and does not perform destructive operations. The risk is minimal as the algorithm's behavior is deterministic and constrained by its input array.
From the tool's definition Tool performs 'ternary search on a sorted array' and 'find the extremum of a unimodal array' — both are query/analysis operations that retrieve or compute values from data without modifying it.
Attacks that exploit this kind of access
The rule that runs ternary_search 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 ternary_search, this is the rule to start with:
ternary_search 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 UnClick, apply this rule, and every ternary_search call is checked against it from then on.
Questions about ternary_search
Ternary search on a sorted array (search mode) or find the extremum of a unimodal array (max/min mode). It is categorised as a Read tool in the UnClick MCP Server, which means it retrieves data without modifying state.
ternary_search accepts 3 parameters: mode, array, target. Required: array. 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 ternary_search: 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.
ternary_search 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 ternary_search 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 ternary_search. 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.
ternary_search 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.
