AI agents use set_suspended to create or update resources in MCP-AnkiConnect — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your MCP-AnkiConnect environment.
This tool modifies card metadata (suspension state) reversibly—suspended cards can be unsuspended, making it a Write operation rather than Destructive. The blast radius is medium because suspending cards affects study workflow and card visibility, but the operation is fully reversible and does not permanently delete data or cause financial impact.
From the tool's definition Tool name 'set_suspended' and description 'Suspend or unsuspend one or more cards' indicate a state-modifying operation that toggles card suspension status.
Documented attack patterns abuse exactly the kind of access set_suspended gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and MCP-AnkiConnect, and nothing reaches the server without passing your rules. This is the rule we recommend for set_suspended:
{
"version": "1",
"default": "deny",
"tools": {
"set_suspended": {
"limits": [
{
"counter": "set_suspended_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}set_suspended 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.
Free to start. No card required.
Suspend or unsuspend one or more cards. It is categorised as a Write tool in the MCP-AnkiConnect MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the MCP-AnkiConnect MCP server in PolicyLayer and add a rule for set_suspended: 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-AnkiConnect. Nothing to install.
set_suspended 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 set_suspended 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 set_suspended. 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.
set_suspended is provided by the MCP-AnkiConnect MCP server (samefarrar/mcp-ankiconnect). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from MCP-AnkiConnect, 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.
