AI agents use create_record to create or update resources in Salesforce — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Salesforce environment.
Creating new records in Salesforce modifies the database by adding data. While reversible (records can be deleted), it represents a data mutation with potential business impact if an AI agent creates unwanted or malicious records. Medium severity reflects that impact scope is limited to creation; the blast radius depends on what records are created, but deletion/correction is possible.
From the tool's definition Tool description explicitly states 'Create a new Salesforce record' and labels it as 'WRITE ACCESS REQUIRED'. The action is reversible via deletion or updating, making it Write rather than Destructive.
Documented attack patterns abuse exactly the kind of access create_record gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Salesforce, and nothing reaches the server without passing your rules. This is the rule we recommend for create_record:
{
"version": "1",
"default": "deny",
"tools": {
"create_record": {
"limits": [
{
"counter": "create_record_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_record stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Create a new Salesforce record (WRITE ACCESS REQUIRED). It is categorised as a Write tool in the Salesforce MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Salesforce MCP server in PolicyLayer and add a rule for create_record: 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. Nothing to install.
create_record is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the create_record 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.
Set action: deny in the PolicyLayer policy for create_record. 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.
create_record is provided by the Salesforce MCP server (tomnagengast/mcp-server-salesforce). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Salesforce, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
