AI agents use mercury_number_generate to create or modify resources in Mercury Number. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call mercury_number_generate repeatedly, creating or modifying resources faster than any human could review. PolicyLayer's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Mercury Number.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Get a random number (1-100) with astrological justification based on Mercury's current zodiac position. Returns the number and cosmic context. Use when you need a number with Mercury retrograde insights or cosmic reasoning.. It is categorised as a Write tool in the Mercury Number MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Mercury Number MCP server in PolicyLayer and add a rule for mercury_number_generate: 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 Mercury Number. Nothing to install.
mercury_number_generate is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the mercury_number_generate 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 mercury_number_generate. 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.
mercury_number_generate is provided by the Mercury Number MCP server (https://gateway.pipeworx.io/mercury-number/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
