Read the entire knowledge graph
AI agents call read_graph to retrieve information from Helm Chart CLI without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries data (the knowledge graph) with no side effects, modifications, or destructive capability. It is a read operation that falls squarely into the 'Read' category. Severity is low because reading data alone poses minimal risk; the blast radius of misuse would be information disclosure only, with no ability to alter systems or commit actions.
From the tool's definition Tool name 'read_graph' and description 'Read the entire knowledge graph' explicitly indicate a read-only operation that retrieves data without modification.

Attacks that exploit this kind of access
Read the entire knowledge graph. It is categorised as a Read tool in the Helm Chart CLI MCP Server, which means it retrieves data without modifying state.
Register the Helm Chart CLI MCP server in PolicyLayer and add a rule for read_graph: 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 Helm Chart CLI. Nothing to install.
read_graph 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 read_graph 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 read_graph. 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.
read_graph is provided by the Helm Chart CLI MCP server (jeff-nasseri/servers). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
