Update an existing todo. You can modify the text, completion status, or alarm time. Only include parameters you want to change.
AI agents use update-todo to create or update resources in BeeMCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your BeeMCP environment.
This tool creates or modifies data (the todo item) in a reversible manner. It does not delete data (which would be Destructive) nor execute arbitrary operations (Execute). The modification of user task management data has medium severity due to potential for unwanted changes to user todos and alarm settings, but changes can be undone by subsequent updates.
From the tool's definition Tool description states 'Update an existing todo' and explicitly allows modification of 'text, completion status, or alarm time'—these are reversible modifications to existing data.
Documented attack patterns abuse exactly the kind of access update-todo gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and BeeMCP, and nothing reaches the server without passing your rules. This is the rule we recommend for update-todo:
{
"version": "1",
"default": "deny",
"tools": {
"update-todo": {
"limits": [
{
"counter": "update-todo_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}update-todo 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.

Update an existing todo. You can modify the text, completion status, or alarm time. Only include parameters you want to change. It is categorised as a Write tool in the BeeMCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Bee MCP server in PolicyLayer and add a rule for update-todo: 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 BeeMCP. Nothing to install.
update-todo 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 update-todo 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 update-todo. 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.
update-todo is provided by the Bee MCP server (okgodoit/beemcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
