manage_aws_glue_resource_policies
AI agents use manage_aws_glue_resource_policies to create or update resources in Amazon Bedrock Knowledge Base Retrieval MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Amazon Bedrock Knowledge Base Retrieval MCP Server environment.
The tool name suggests it modifies AWS Glue resource policies, which are access control mechanisms. Modifying policies can grant or revoke permissions, making this a Write operation affecting system security posture. Severity is high because incorrect policy changes could grant unintended access or break legitimate access.
From the tool's definition Tool name 'manage_aws_glue_resource_policies' indicates modification of AWS Glue resource policies; 'manage' typically implies create/update operations on access control policies.
Documented attack patterns abuse exactly the kind of access manage_aws_glue_resource_policies gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Amazon Bedrock Knowledge Base Retrieval MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for manage_aws_glue_resource_policies:
{
"version": "1",
"default": "deny",
"tools": {
"manage_aws_glue_resource_policies": {
"limits": [
{
"counter": "manage_aws_glue_resource_policies_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
} manage_aws_glue_resource_policies stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

All 805 Amazon Bedrock Knowledge Base Retrieval MCP Server tools →
manage_aws_glue_resource_policies. It is categorised as a Write tool in the Amazon Bedrock Knowledge Base Retrieval MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Amazon Bedrock Knowledge Base Retrieval MCP Server MCP server in PolicyLayer and add a rule for manage_aws_glue_resource_policies: 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 Amazon Bedrock Knowledge Base Retrieval MCP Server. Nothing to install.
manage_aws_glue_resource_policies 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 manage_aws_glue_resource_policies 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 manage_aws_glue_resource_policies. 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.
manage_aws_glue_resource_policies is provided by the Amazon Bedrock Knowledge Base Retrieval MCP Server MCP server (awslabs.bedrock-kb-retrieval-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Amazon Bedrock Knowledge Base Retrieval MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
