soql_query · MCP Salesforce Lite MCP: Risk & Policy

WHAT IT DOES

What soql_query does on MCP Salesforce Lite

AI agents invoke soql_query to trigger actions in MCP Salesforce Lite. 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 soql_query needs a policy

SOQL is Salesforce's query language, but the tool executes arbitrary queries supplied as arguments. While standard SOQL is read-only (SELECT only), the description does not restrict the input, and in some Salesforce contexts SOQL can be embedded in operations with side effects.

From the tool's definition "Execute a SOQL query against Salesforce" — the tool explicitly executes arbitrary SOQL queries

soql_query Rate-limited

soql_query 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.
