List all Service Level Objectives (SLOs) in Application Signals. Use this tool to: - Get a complete list of all SLOs in your account - Discover SLO names and ARNs for use with other tools - Filter SLOs by service attributes - See basic SLO information including creation time and operation names ...
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_slos 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_slos 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.

List all Service Level Objectives (SLOs) in Application Signals. Use this tool to: - Get a complete list of all SLOs in your account - Discover SLO names and ARNs for use with other tools - Filter SLOs by service attributes - See basic SLO information including creation time and operation names Returns a formatted list showing: - SLO name and ARN - Associated service key attributes - Operation name being monitored - Creation timestamp - Total count of SLOs found This tool is useful for: - SLO discovery and inventory - Finding SLO names to use with get_slo() or audit_service_health() - Understanding what operations are being monitored. 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_slos. 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_slos 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_slos 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_slos. 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_slos 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.
