restful · MCP Salesforce Connector MCP: Risk & Policy

WHAT IT DOES

What restful does on MCP Salesforce Connector

AI agents invoke restful to trigger actions in MCP Salesforce Connector. 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 restful needs a policy

The tool's effects are entirely argument-dependent: it could retrieve data (Read), modify records (Write), delete records (Destructive), execute Apex code (Execute), or trigger financial operations (Financial) based on which REST endpoint and payload the LLM constructs.

From the tool's definition Tool description states 'Makes a direct REST API call to Salesforce' — this is a pass-through to arbitrary Salesforce REST endpoints.

restful Rate-limited

restful 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.
