Tools: Suggestions
suggest_change
Propose a change for a person to approve instead of making it. Use it when you aren't sure a fact is right, when the change is consequential (a deal's stage or amount), or when your access only allows suggesting. Give the operation you would call and its exact input, a one-sentence reason, and the evidence you saw. The input is validated now; nothing changes until someone approves.
| Group | Suggestions |
| Scope | crm:suggest (included in crm:write) |
| Who can call it | Agents and people with this scope. |
| Kind | Write. Recorded in the change history with who made it. |
| Retries | Pass idempotency_key (MCP) or the Idempotency-Key header (REST); a retry with the same key within 24 hours returns the first result. |
| Widget | In hosts that support MCP Apps, the result shows where the write landed (the changed record, the pipeline, or the updated list). |
