Part of the AWS Support MCP Server MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents use create_support_case to create or modify resources in AWS Support MCP Server. 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 create_support_case 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 AWS Support MCP Server.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Create a new AWS Support case. ## Prerequisites 1. **describe_services** → get valid `service_code` and `category_code` values 2. (Optional) **describe_create_case_options** → check support hours and language availability 3. (Optional) **describe_supported_languages** → check if your preferred language is supported Severity codes are: low, normal, high, urgent, critical. Pick based on impact — no need to call describe_severity_levels. ## Attaching files Call **add_attachments_to_set** first to upload files, then pass the returned `attachmentSetId` as the `attachment_set_id` parameter here. ## Example ``` create_support_case( subject='EC2 instance not starting', service_code='amazon-elastic-compute-cloud-linux', category_code='using-aws', severity_code='urgent', communication_body='My EC2 instance i-1234567890abcdef0 is not starting.', ) ``` ## Severity Level Guidelines - low (General guidance): You have a general development question or want to request a feature. - normal (System impaired): Non-critical functions are behaving abnormally or you have a time-sensitive development question. - high (Production system impaired): Important functions are impaired but a workaround exists. - urgent (Production system down): Your business is significantly impacted and no workaround exists. - critical (Business-critical system down): Your business is at risk and critical functions are unavailable.. It is categorised as a Write tool in the AWS Support MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Add a rule in your Intercept YAML policy under the tools section for create_support_case. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the AWS Support MCP Server MCP server.
create_support_case 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 create_support_case 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.
Set action: deny in the Intercept policy for create_support_case. 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.
create_support_case is provided by the AWS Support MCP Server MCP server (awslabs.aws-support-mcp-server). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
