AI agents use create_note to create or update resources in LunaTask MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your LunaTask MCP Server environment.
The 'create_note' tool creates new data (notes) within the LunaTask productivity system. This is reversible via deletion, making it a Write action rather than Destructive. Severity is medium because misuse could add unwanted notes/clutter to a user's task management system, but the impact is limited to data creation without financial consequences or irreversible harm.
From the tool's definition Tool name 'create_note' indicates data creation. Sibling tools on the same server include destructive operations (delete_note, delete_person, delete_task) and other write operations (create_journal_entry, create_task, update_note), establishing the pattern…
Documented attack patterns abuse exactly the kind of access create_note gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and LunaTask MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for create_note:
{
"version": "1",
"default": "deny",
"tools": {
"create_note": {
"limits": [
{
"counter": "create_note_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_note 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.

create_note. It is categorised as a Write tool in the LunaTask MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the LunaTask MCP Server MCP server in PolicyLayer and add a rule for create_note: 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 LunaTask MCP Server. Nothing to install.
create_note 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 create_note 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 create_note. 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.
create_note is provided by the LunaTask MCP Server MCP server (tensorfreitas/lunatask-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from LunaTask MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
