Get field mappings for a specific Elasticsearch index
AI agents call get_mappings 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 schema/mapping metadata from an Elasticsearch index. It performs a query operation with no side effects, no data modification, and no irreversible actions. Belongs firmly in the Read category with low severity since it only exposes index structure information.
From the tool's definition Tool name is 'get_mappings' and description states 'Get field mappings for a specific Elasticsearch index' — retrieval-only operation with no modification or deletion
Attacks that exploit this kind of access
Get field mappings for a specific Elasticsearch index. 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_mappings: 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_mappings 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_mappings 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_mappings. 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_mappings 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.
