What httpbin_uuid does on UnClick
AI agents call httpbin_uuid 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 httpbin_uuid is rated Low
This tool retrieves or generates a value (UUID) without creating, modifying, deleting, or executing any consequential operations. It is a stateless, side-effect-free read operation. Even in the context of a marketplace with diverse tool categories, a UUID generator poses minimal risk when misused by an agent.
From the tool's definition Tool description states 'Generate a random UUID via httpbin' — a pure generation/retrieval operation with no side effects, data modification, or external action beyond fetching a UUID.
Attacks that exploit this kind of access
The rule that runs httpbin_uuid 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 httpbin_uuid, this is the rule to start with:
httpbin_uuid 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 httpbin_uuid call is checked against it from then on.
Questions about httpbin_uuid
Generate a random UUID via httpbin. It is categorised as a Read tool in the UnClick MCP Server, which means it retrieves data without modifying state.
Register the UnClick MCP server in PolicyLayer and add a rule for httpbin_uuid: 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.
httpbin_uuid 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 httpbin_uuid 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 httpbin_uuid. 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.
httpbin_uuid 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.
