WHAT IT DOES

What inspect_knowledge_graph does on Elasticsearch Knowledge Graph for MCP

AI agents call inspect_knowledge_graph to retrieve information from Elasticsearch Knowledge Graph for MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

THE RISK

Low Risk

Why inspect_knowledge_graph needs a policy

This tool retrieves and queries data from the knowledge graph without creating, modifying, or deleting information. The inspection pattern and mention of freshness metadata confirm it is a read-only query operation. No side effects or data mutations occur. Lowest risk category applies.

From the tool's definition Tool performs 'knowledge graph inspection' and 'retrieve relevant entities and relations' with no modification verbs. Description indicates query/retrieval operations only, returning metadata about stored data.

POLICY

How to control inspect_knowledge_graph

PolicyLayer is an MCP gateway — it sits between your AI agents and Elasticsearch Knowledge Graph for MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for inspect_knowledge_graph:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "inspect_knowledge_graph": {}
  }
}

inspect_knowledge_graph is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register Elasticsearch Knowledge Graph for MCP — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
