THE RISK

Low Risk

Why bulk_load_metadata needs a policy

This tool reads/retrieves metadata about RFC functions in bulk. It does not execute, modify, or delete data. The medium severity reflects that bulk access to SAP RFC metadata could expose sensitive system architecture and function signatures, giving an attacker a map of available operations.

From the tool's definition 'Bulk load metadata for multiple RFC functions' - retrieves metadata about SAP RFC functions in bulk

POLICY

How to control bulk_load_metadata

PolicyLayer is an MCP gateway — it sits between your AI agents and SAP RFC MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for bulk_load_metadata:

policy.json

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

bulk_load_metadata 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 SAP RFC MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about bulk_load_metadata

What does the bulk_load_metadata tool do? +

Bulk load metadata for multiple RFC functions. It is categorised as a Read tool in the SAP RFC MCP Server MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on bulk_load_metadata? +

Register the SAP RFC MCP Server MCP server in PolicyLayer and add a rule for bulk_load_metadata: 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 SAP RFC MCP Server. Nothing to install.

What risk level is bulk_load_metadata? +

bulk_load_metadata is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit bulk_load_metadata? +

Yes. Add a rate_limit block to the bulk_load_metadata 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.

How do I block bulk_load_metadata completely? +

Set action: deny in the PolicyLayer policy for bulk_load_metadata. 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.

What MCP server provides bulk_load_metadata? +

bulk_load_metadata is provided by the SAP RFC MCP Server MCP server (thupalo/sap-rfc-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every SAP RFC MCP Server tool call.

Start from SAP RFC MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
