Get alias information for a specific index.
AI agents call get_alias to retrieve information from Elasticsearch/OpenSearch MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves existing alias metadata associated with an index without modifying, creating, deleting, or executing anything. It has no side effects and presents minimal risk—the information returned is already accessible through normal cluster queries.
From the tool's definition Tool name 'get_alias' and description 'Get alias information for a specific index' indicate a retrieval operation. The verb 'Get' and the absence of modification, deletion, or execution language confirm this is a read-only query.
Attacks that exploit this kind of access
Get alias information for a specific index. It is categorised as a Read tool in the Elasticsearch/OpenSearch MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Elasticsearch/OpenSearch MCP Server MCP server in PolicyLayer and add a rule for get_alias: 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 Elasticsearch/OpenSearch MCP Server. Nothing to install.
get_alias 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 get_alias 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 get_alias. 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.
get_alias is provided by the Elasticsearch/OpenSearch MCP Server MCP server (rbedoyag/elasticsearch-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
