AI agents use resumeTask to create or update resources in Ava — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Ava environment.
This tool modifies task state reversibly—it changes a task from paused to resumed status. This is a Write operation since it alters data state (task status) without permanent destruction. Severity is medium because misuse could disrupt team workflows and cause confusion in task tracking, though the effect is reversible (the task can be paused again).
From the tool's definition Tool name 'resumeTask' combined with sibling tools (pauseTask, startTask, completeTask, updateTask) indicates state modification operations.
Documented attack patterns abuse exactly the kind of access resumeTask gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Ava, and nothing reaches the server without passing your rules. This is the rule we recommend for resumeTask:
{
"version": "1",
"default": "deny",
"tools": {
"resumeTask": {
"limits": [
{
"counter": "resumetask_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}resumeTask 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.

Register the Ava MCP server in PolicyLayer and add a rule for resumeTask: 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 Ava. Nothing to install.
resumeTask 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 resumeTask 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 resumeTask. 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.
resumeTask is provided by the Ava MCP server (yutakobayashidev/ava). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Ava, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
