Get index aliases from Elasticsearch
AI agents call get_aliases to retrieve information from Octodet Elasticsearch without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves alias information from Elasticsearch without modifying, executing, or deleting any data. It is a simple informational query operation, consistent with the Read category for tools that retrieve or query data without side effects.
From the tool's definition Tool name 'get_aliases' and description 'Get index aliases from Elasticsearch' indicate a retrieval operation with no side effects. 'Get' is a read verb, and aliases are metadata about index configurations.
Attacks that exploit this kind of access
Get index aliases from Elasticsearch. It is categorised as a Read tool in the Octodet Elasticsearch MCP Server, which means it retrieves data without modifying state.
Register the Octodet Elasticsearch MCP server in PolicyLayer and add a rule for get_aliases: 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 Octodet Elasticsearch. Nothing to install.
get_aliases 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_aliases 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_aliases. 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_aliases is provided by the Octodet Elasticsearch MCP server (octodet/elasticsearch-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
