WHEN AI AGENTS USE THIS TOOL

AI agents call list-prompt-versions to retrieve information from Phoenix without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions — but you may still want rate limits to control API costs.

WHY ENFORCE A POLICY ON LIST-PROMPT-VERSIONS

Even though list-prompt-versions only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.

RECOMMENDED POLICY

Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

phoenix.yaml 
tools:
  list-prompt-versions:
    rules:
      - action: allow

FREQUENTLY ASKED QUESTIONS

What does the list-prompt-versions tool do?

List all versions of a given prompt. It is categorised as a Read tool in the Phoenix MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on list-prompt-versions?

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

What risk level is list-prompt-versions?

list-prompt-versions is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit list-prompt-versions?

Yes. Add a rate_limit block to the list-prompt-versions 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 list-prompt-versions completely?

Set action: deny in the Intercept policy for list-prompt-versions. 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 list-prompt-versions?

list-prompt-versions is provided by the Phoenix MCP server (Arize-ai/phoenix). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
