open · Salesforce CLI MCP Server MCP: Risk & Policy

WHAT IT DOES

What open does on Salesforce CLI MCP Server

AI agents invoke open to trigger actions in Salesforce CLI MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why open needs a policy

This tool launches a browser session to open a Salesforce org, which is an external operation with side effects (opening a browser, potentially initiating an authenticated session). It falls under Execute as it triggers an external operation. The severity is medium because it could expose an authenticated Salesforce session in a browser, but does not directly read, write, or destroy data by itself.

From the tool's definition 'Open your Salesforce org in a browser' — triggers an external browser action/operation

Verdict

open Rate-limited

open stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

Questions about open

What does the open tool do? +

Open your Salesforce org in a browser. To open a specific page, specify the portion of the URL after. It is categorised as a Execute tool in the Salesforce CLI MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on open? +

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

What risk level is open? +

open is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit open? +

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

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