Update an existing reviewlist entry — typically to extend or shorten the expiration window without removing and re-adding the entry.
AI agents use update_reviewlist_entry to create or update resources in Mcp Afip — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Mcp Afip environment.
This tool modifies an existing record (reviewlist entry) by changing its expiration window. This is a reversible write operation—the change can be undone by updating it again to a different expiration time. It does not delete data (Destructive), execute arbitrary code (Execute), move money (Financial), or merely read data (Read).
From the tool's definition Tool name 'update_reviewlist_entry' and description states 'Update an existing reviewlist entry — typically to extend or shorten the expiration window'. The verb 'update' indicates modification of existing data.

PolicyLayer is an MCP gateway — it sits between your AI agents and Mcp Afip, and nothing reaches the server without passing your rules. This is the rule we recommend for update_reviewlist_entry:
{
"version": "1",
"default": "deny",
"tools": {
"update_reviewlist_entry": {
"limits": [
{
"counter": "update_reviewlist_entry_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}update_reviewlist_entry 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.

Update an existing reviewlist entry — typically to extend or shorten the expiration window without removing and re-adding the entry. It is categorised as a Write tool in the Mcp Afip MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Mcp Afip MCP server in PolicyLayer and add a rule for update_reviewlist_entry: 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 Mcp Afip. Nothing to install.
update_reviewlist_entry 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 update_reviewlist_entry 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 update_reviewlist_entry. 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.
update_reviewlist_entry is provided by the Mcp Afip MCP server (codespar/mcp-dev-latam). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Mcp Afip, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
