oci_iam_list_users

// WHEN AI AGENTS USE THIS TOOL

AI agents call oci_iam_list_users to retrieve information from Oracle Cloud 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 OCI_IAM_LIST_USERS

Even though oci_iam_list_users 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.

What does the oci_iam_list_users tool do? +

List IAM users in the tenancy. It is categorised as a Read tool in the Oracle Cloud MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on oci_iam_list_users? +

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

What risk level is oci_iam_list_users? +

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

Can I rate-limit oci_iam_list_users? +

Yes. Add a rate_limit block to the oci_iam_list_users 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 oci_iam_list_users completely? +

Set action: deny in the Intercept policy for oci_iam_list_users. 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 oci_iam_list_users? +

oci_iam_list_users is provided by the Oracle Cloud MCP server (oracle-cloud-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
