Get full detail of an exported tool from the mcpGraph
AI agents call getGraphTool to retrieve information from mcpGraph without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata and configuration details about an existing graph tool without modifying, executing, or deleting any data. It is a query operation with no side effects, fitting the Read category. Severity is low because exposure would only leak tool definitions and configurations, not enable direct harm.
From the tool's definition Tool name 'getGraphTool' and description 'Get full detail of an exported tool' indicate a retrieval operation. The verb 'Get' and lack of any modification language confirm read-only behavior.
Documented attack patterns abuse exactly the kind of access getGraphTool gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and mcpGraph, and nothing reaches the server without passing your rules. This is the rule we recommend for getGraphTool:
{
"version": "1",
"default": "deny",
"tools": {
"getGraphTool": {}
}
}getGraphTool is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get full detail of an exported tool from the mcpGraph. It is categorised as a Read tool in the mcpGraph MCP Server, which means it retrieves data without modifying state.
Register the mcpGraph MCP server in PolicyLayer and add a rule for getGraphTool: 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 mcpGraph. Nothing to install.
getGraphTool 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 getGraphTool 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 getGraphTool. 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.
getGraphTool is provided by the mcpGraph MCP server (teamsparkai/mcpgraph). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from mcpGraph, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
