AI agents call generate_ulid 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 only generates and returns identifier strings. It has no side effects, does not modify any data, does not execute code, and involves no financial or destructive operations. It is purely a data-generation/read-like utility.

Generate one or more ULIDs (Universally Unique Lexicographically Sortable Identifiers). ULIDs are 26-character identifiers that combine a timestamp with random data, enabling chronological sorting while maintaining uniqueness. Ideal for time-series data, event logs, or any context requiring time-ordered records. Note: The timestamp component creates predictability, making ULIDs unsuitable for security-sensitive applications where IDs must not reveal creation time. 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_ulid: 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_ulid 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_ulid 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_ulid. 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_ulid 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.
