Why set_default_org needs a policy

This tool modifies persistent system state (the default org setting) that affects the operational context of all sibling tools. While not destructive (it does not delete data) and not immediately executing operations on a target system, it creates a configuration change that can cause all subsequent tool invocations to operate against an unintended org.

From the tool's definition set_default_org permanently changes configuration that 'persists across sessions' and affects all downstream tools' behavior by redirecting them to a different org.

POLICY

How to control set_default_org

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "set_default_org": {
      "limits": [
        {
          "counter": "set_default_org_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

set_default_org 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.

Create a free account and register Salesforce 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 set_default_org

What does the set_default_org tool do? +

Set the default target org for the Salesforce CLI. Once set, all tools will use this org by default when no targetOrg is specified. The value persists across sessions. It is categorised as a Write tool in the Salesforce MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on set_default_org? +

Register the Salesforce MCP Server MCP server in PolicyLayer and add a rule for set_default_org: 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 Salesforce MCP Server. Nothing to install.

What risk level is set_default_org? +

set_default_org is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit set_default_org? +

Yes. Add a rate_limit block to the set_default_org 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 set_default_org completely? +

Set action: deny in the PolicyLayer policy for set_default_org. 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 set_default_org? +

set_default_org is provided by the Salesforce MCP Server MCP server (advancedcommunities/salesforce-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 Salesforce MCP Server tool call.

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