What harmonic_series does on UnClick
AI agents call harmonic_series 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 harmonic_series is rated Low
This is a pure computational function that retrieves a mathematical result based on input parameters. It has no capability to read sensitive data, write to systems, execute code, delete resources, or move money. The blast radius of misuse is negligible—an AI agent calling this tool repeatedly would only waste computational resources without causing harm.
From the tool's definition Tool performs a mathematical calculation (partial sum of harmonic series) with no side effects. The description indicates it 'Calculate[s]' a mathematical formula, returning a computed value without modifying, creating, deleting, or executing any external…
Attacks that exploit this kind of access
The rule that runs harmonic_series 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 harmonic_series, this is the rule to start with:
harmonic_series 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 harmonic_series call is checked against it from then on.
Questions about harmonic_series
Calculate partial sum of the harmonic series H(n) = 1 + 1/2 + 1/3 + ... + 1/n. It is categorised as a Read tool in the UnClick MCP Server, which means it retrieves data without modifying state.
harmonic_series accepts 1 parameter: n. Required: n. 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 harmonic_series: 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.
harmonic_series 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 harmonic_series 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 harmonic_series. 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.
harmonic_series 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.
