FAQ

Questions about sf_update_custom_object

What does the sf_update_custom_object tool do? +

Updates object-level properties of an existing CUSTOM object (label, plural label, description, feature toggles, sharing model, deployment status). Only the properties you pass are changed. Fields, validation rules, record types and list views are never included in the payload, so they cannot be affected by this call. Changes are classified by risk. SAFE changes (labels, description, feature toggles) apply immediately. GUARDED changes (sharingModel, deploymentStatus) do NOT apply on the first call: you get back an impact report — what references this object, plus Salesforce. It is categorised as a Write tool in the Salesforce Metadata Mcp MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on sf_update_custom_object? +

Register the Salesforce Metadata MCP server in PolicyLayer and add a rule for sf_update_custom_object: 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 Metadata Mcp. Nothing to install.

What risk level is sf_update_custom_object? +

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

Can I rate-limit sf_update_custom_object? +

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