Resume a check that was paused (typically awaiting_applicant or paused states). No-op on checks that are already running / complete.
AI agents use resume_check 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.
The tool changes the status of a check object from paused/awaiting to active/running, which constitutes a state modification. This is reversible (check can be paused again), so it falls under Write rather than Destructive or Execute. In the context of Argentine tax authority invoicing, resuming a check could affect invoice processing workflows.
From the tool's definition Tool resumes a paused check, transitioning it from 'awaiting_applicant' or 'paused' states to running state. This modifies the state of an existing record in the AFIP system.
Documented attack patterns abuse exactly the kind of access resume_check gives an agent:
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 resume_check:
{
"version": "1",
"default": "deny",
"tools": {
"resume_check": {
"limits": [
{
"counter": "resume_check_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}resume_check 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.

Resume a check that was paused (typically awaiting_applicant or paused states). No-op on checks that are already running / complete. 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 resume_check: 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.
resume_check 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 resume_check 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 resume_check. 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.
resume_check 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.
