AI agents call get_available_services to retrieve information from AWS without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only query of AWS China documentation to list available services and provide documentation references. It has no capability to modify, delete, execute, or commit financial transactions. The output is informational markdown content. The blast radius if misused by an agent is minimal—worst case would be accessing information about available services, which is already public documentation.
From the tool's definition Tool description states it 'Fetch available services' and 'retrieves a list of available services and their documentation URLs'. The verb 'Fetch' and 'retrieves' indicate data retrieval with no side effects.
Documented attack patterns abuse exactly the kind of access get_available_services gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and AWS, and nothing reaches the server without passing your rules. This is the rule we recommend for get_available_services:
{
"version": "1",
"default": "deny",
"tools": {
"get_available_services": {}
}
}get_available_services is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Fetch available services from AWS China documentation. ## Usage Available services in AWS China are different from global AWS services. This tool retrieves a list of available services and their documentation URLs. ## Output Format The output is formatted as markdown text with: - Preserved headings and structure - Code blocks for examples - Lists and tables converted to markdown format Args: ctx: MCP context for logging and error handling Returns: Markdown content of the AWS China documentation about available services. It is categorised as a Read tool in the AWS MCP Server, which means it retrieves data without modifying state.
Register the AWS MCP server in PolicyLayer and add a rule for get_available_services: 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 AWS. Nothing to install.
get_available_services 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 get_available_services 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 get_available_services. 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.
get_available_services is provided by the AWS MCP server (@awslabs/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from AWS, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
