Part of the CloudWatch Application Signals MCP Server MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents call list_grouping_attribute_definitions to retrieve information from CloudWatch Application Signals MCP Server 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.
Even though list_grouping_attribute_definitions 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.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

GROUPING CONFIGURATION TOOL - List all custom grouping attribute definitions. Use this tool when users ask: - "What grouping attributes are configured?" - "List all custom groups" - "What groups have been defined in my account?" - "Show me the grouping configuration" - "What grouping attributes are available?" **WHAT THIS TOOL DOES:** Retrieves all custom grouping attribute definitions configured in the account. These definitions determine how services are logically grouped based on telemetry attributes, AWS tags, or predefined mappings. **OUTPUT INCLUDES:** - List of all grouping attribute definitions - Grouping name (e.g., "BusinessUnit", "Team") - Source keys used to derive group values - Default grouping value when source data is missing - Last configuration update timestamp **EXAMPLES:** ``` list_grouping_attribute_definitions() ```. It is categorised as a Read tool in the CloudWatch Application Signals MCP Server MCP Server, which means it retrieves data without modifying state.
Add a rule in your Intercept YAML policy under the tools section for list_grouping_attribute_definitions. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the CloudWatch Application Signals MCP Server MCP server.
list_grouping_attribute_definitions 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 list_grouping_attribute_definitions 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 list_grouping_attribute_definitions. 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.
list_grouping_attribute_definitions is provided by the CloudWatch Application Signals MCP Server MCP server (awslabs.cloudwatch-applicationsignals-mcp-server). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
