[ASYNC] Sync full project manifest + internal docs. Returns taskId.
AI agents use sync_project_assets to create or update resources in N2n Nexus — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your N2n Nexus environment.
This tool creates or modifies project data (manifest and internal documentation) rather than merely retrieving it. While 'sync' could imply read-only operations, in the context of a 'project vault' managing 'assets', synchronization typically involves bidirectional data updates.
From the tool's definition Tool description states 'Sync full project manifest + internal docs' which involves synchronizing and potentially modifying project data.
Documented attack patterns abuse exactly the kind of access sync_project_assets gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and N2n Nexus, and nothing reaches the server without passing your rules. This is the rule we recommend for sync_project_assets:
{
"version": "1",
"default": "deny",
"tools": {
"sync_project_assets": {
"limits": [
{
"counter": "sync_project_assets_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}sync_project_assets 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.

[ASYNC] Sync full project manifest + internal docs. Returns taskId. It is categorised as a Write tool in the N2n Nexus MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the N2n Nexus MCP server in PolicyLayer and add a rule for sync_project_assets: 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 N2n Nexus. Nothing to install.
sync_project_assets 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 sync_project_assets 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 sync_project_assets. 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.
sync_project_assets is provided by the N2n Nexus MCP server (n2ns/n2n-nexus). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from N2n Nexus, 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.
