THE RISK

Low Risk

Why analyze_log_group needs a policy

Log group analysis is fundamentally a read operation that retrieves and processes log data without side effects. AWS CloudWatch log analysis does not create, modify, delete, or execute external operations. Even with empty description, the name pattern matches other read tools in the sibling list (e.g., 'aggregate', 'analyze_canary_failures'). Low confidence due to missing documentation, but categorization is secure.

From the tool's definition Tool name 'analyze_log_group' suggests querying and analyzing CloudWatch logs without modification. The 'analyze' verb typically indicates inspection/review operations. Description is empty, reducing confidence.

POLICY

How to control analyze_log_group

PolicyLayer is an MCP gateway — it sits between your AI agents and AWS API MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for analyze_log_group:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "analyze_log_group": {}
  }
}

analyze_log_group is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register AWS API MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about analyze_log_group

What does the analyze_log_group tool do? +

analyze_log_group. It is categorised as a Read tool in the AWS API MCP Server MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on analyze_log_group? +

Register the AWS API MCP Server MCP server in PolicyLayer and add a rule for analyze_log_group: 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 API MCP Server. Nothing to install.

What risk level is analyze_log_group? +

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

Can I rate-limit analyze_log_group? +

Yes. Add a rate_limit block to the analyze_log_group 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.

How do I block analyze_log_group completely? +

Set action: deny in the PolicyLayer policy for analyze_log_group. 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 analyze_log_group? +

analyze_log_group is provided by the AWS API MCP Server MCP server (awslabs.aws-api-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every AWS API MCP Server tool call.

Start from AWS API MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
