What longest_increasing_subsequence does on UnClick
AI agents call longest_increasing_subsequence 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.

Why longest_increasing_subsequence is rated Low
This is a stateless, read-only computational utility that analyzes data structures and returns a result. There is no capability to modify state, execute arbitrary code, delete data, or commit financial actions. The worst-case misuse would be resource exhaustion (CPU time on large inputs), which constitutes low severity. The tool is inherently safe regardless of how an AI agent uses it.
From the tool's definition Tool performs a computational analysis (finding longest increasing subsequence) with no side effects. The description indicates it returns a result based on input data without modifying, deleting, executing external code, or moving funds.
Attacks that exploit this kind of access
The rule that runs longest_increasing_subsequence 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 longest_increasing_subsequence, this is the rule to start with:
longest_increasing_subsequence 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 longest_increasing_subsequence call is checked against it from then on.
Questions about longest_increasing_subsequence
Find the longest increasing subsequence in O(n log n) time using patience sorting. It is categorised as a Read tool in the UnClick MCP Server, which means it retrieves data without modifying state.
longest_increasing_subsequence accepts 1 parameter: values. Required: values. 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 longest_increasing_subsequence: 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.
longest_increasing_subsequence 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 longest_increasing_subsequence 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 longest_increasing_subsequence. 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.
longest_increasing_subsequence 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.
