durationMin

// WHEN AI AGENTS USE THIS TOOL

AI agents use durationMin to create or modify resources in Jaeger. 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.

// WHY ENFORCE A POLICY ON DURATIONMIN

Without a policy, an AI agent could call durationMin repeatedly, creating or modifying resources faster than any human could review. Intercept's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Jaeger.

// RECOMMENDED POLICY

Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

// FAQ

What does the durationMin tool do? +

durationMin. It is categorised as a Write tool in the Jaeger MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on durationMin? +

Add a rule in your Intercept YAML policy under the tools section for durationMin. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Jaeger MCP server.

What risk level is durationMin? +

durationMin is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit durationMin? +

Yes. Add a rate_limit block to the durationMin rule in your Intercept 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.

How do I block durationMin completely? +

Set action: deny in the Intercept policy for durationMin. 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.

What MCP server provides durationMin? +

durationMin is provided by the Jaeger MCP server (jaeger-mcp-server). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
