WHAT IT DOES

What read_graph does on Project Guardian MCP

AI agents call read_graph to retrieve information from Project Guardian MCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why read_graph is rated Low

This tool retrieves project knowledge graph data without side effects. It performs a query operation to fetch existing data for analysis or display. While it may expose sensitive project information if misused, the blast radius is limited to information disclosure rather than data modification, deletion, or financial impact. Classified as Read with low severity due to the informational nature of the operation.

From the tool's definition Tool name is 'read_graph' and description states 'Read the entire project knowledge graph' - the verb 'Read' explicitly indicates data retrieval with no modification.

RECOMMENDED RULE

The rule that runs read_graph safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Project Guardian MCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For read_graph, this is the rule to start with:

read_graph Allowed

read_graph is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

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

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Project Guardian MCP, apply this rule, and every read_graph call is checked against it from then on.
