Rollback a transaction by its ID to undo all changes and discard the transaction
AI agents invoke execute_rollback to trigger actions in PostgreSQL Full Access MCP Server. 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.
While rollback is reversible (unlike Destructive operations), it is an Execute category tool because it triggers external database operations and manipulates transactional state.
From the tool's definition Tool executes transaction rollback operations via explicit ID parameter. Description states 'Rollback a transaction by its ID to undo all changes and discard the transaction', which is an Execute action—it triggers a database operation whose effects depend on…
Documented attack patterns abuse exactly the kind of access execute_rollback gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and PostgreSQL Full Access MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for execute_rollback:
{
"version": "1",
"default": "deny",
"tools": {
"execute_rollback": {
"limits": [
{
"counter": "execute_rollback_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}execute_rollback 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.

Rollback a transaction by its ID to undo all changes and discard the transaction. It is categorised as a Execute tool in the PostgreSQL Full Access MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the PostgreSQL Full Access MCP Server MCP server in PolicyLayer and add a rule for execute_rollback: 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 PostgreSQL Full Access MCP Server. Nothing to install.
execute_rollback is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the execute_rollback 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 execute_rollback. 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.
execute_rollback is provided by the PostgreSQL Full Access MCP Server MCP server (syahiidkamil/mcp-postgres-full-access). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from PostgreSQL Full Access MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
