WHAT IT DOES

What hello_world does on Salesforce Metadata Mcp

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs hello_world safely

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

hello_world Rate-limited

hello_world stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
