Generate one or more UUIDs (Universally Unique Identifiers). You may elect to have the UUID presented as a URN and v4 or v7 UUIDs with v7 as the default. Avoid using UUID versions less than 4 unless the user asks for it explicitly. UUID v7 is a 36-character (with hyphens) time-ordered identifier ...
AI agents call generate_uuid to retrieve information from Unique Id Generator without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool generates unique identifiers locally without any side effects, data modification, execution of external commands, or financial operations. It purely produces output values (UUIDs) for use by the caller, analogous to a read/query operation with no external impact.
From the tool's definition Generate one or more UUIDs (Universally Unique Identifiers)... UUID v7 is a 36-character (with hyphens) time-ordered identifier that improves upon earlier UUID versions by combining timestamp and random data.

Generate one or more UUIDs (Universally Unique Identifiers). You may elect to have the UUID presented as a URN and v4 or v7 UUIDs with v7 as the default. Avoid using UUID versions less than 4 unless the user asks for it explicitly. UUID v7 is a 36-character (with hyphens) time-ordered identifier that improves upon earlier UUID versions by combining timestamp and random data. It provides excellent uniqueness guarantees with widespread support across languages and databases. While more standardized than other options, UUID v7. It is categorised as a Read tool in the Unique Id Generator MCP Server, which means it retrieves data without modifying state.
Register the Unique Id Generator MCP server in PolicyLayer and add a rule for generate_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 Unique Id Generator. Nothing to install.
generate_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 generate_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 generate_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.
generate_uuid is provided by the Unique Id Generator MCP server (pyroxin/mcp-server-unique-id-generator). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
