GrantHealthOmicsRepositoryAccess
AI agents use GrantHealthOmicsRepositoryAccess to create or update resources in Awslabs Amazon Sns Sqs — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Awslabs Amazon Sns Sqs environment.
The tool name suggests granting access to a HealthOmics repository, which is a Write/permission-modification operation. However, the description is empty, so confidence is low. Granting access modifies IAM or resource-based policies, which is reversible (access can be revoked), placing it in the Write category. Severity is medium as misconfigured access grants could expose sensitive health data.

PolicyLayer is an MCP gateway — it sits between your AI agents and Awslabs Amazon Sns Sqs, and nothing reaches the server without passing your rules. This is the rule we recommend for GrantHealthOmicsRepositoryAccess:
{
"version": "1",
"default": "deny",
"tools": {
"GrantHealthOmicsRepositoryAccess": {
"limits": [
{
"counter": "granthealthomicsrepositoryaccess_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}GrantHealthOmicsRepositoryAccess 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.

Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Awslabs Amazon Sns Sqs. Nothing to install.
GrantHealthOmicsRepositoryAccess 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 GrantHealthOmicsRepositoryAccess 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 GrantHealthOmicsRepositoryAccess. 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.
GrantHealthOmicsRepositoryAccess is provided by the Awslabs Amazon Sns Sqs MCP server (awslabs.amazon-sns-sqs-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
