What eertree does on UnClick
AI agents invoke eertree 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 |
|---|---|---|---|
text | string | Yes | Input string to analyse |
Parameters from the server's own tool schema.
Why eertree is rated High
The tool executes a specific algorithm (eertree construction) to process and analyze input data. While it does not modify external state, delete data, or move money, it does trigger computational execution whose output depends on the input string provided. This falls under Execute rather than Read, as it performs an active algorithmic transformation rather than passive data retrieval.
From the tool's definition Tool performs an algorithmic operation ('build a palindromic tree') and returns computational results ('count distinct palindromic substrings'). This involves executing a data structure construction algorithm on provided input.
Attacks that exploit this kind of access
The rule that runs eertree 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 eertree, this is the rule to start with:
eertree 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 eertree call is checked against it from then on.
Questions about eertree
Build a palindromic tree (eertree) to count distinct palindromic substrings. 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.
eertree accepts 1 parameter: text. Required: text. 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 eertree: 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.
eertree 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 eertree 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 eertree. 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.
eertree 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.
