This tool modifies task data in Todoist in a reversible manner. It does not delete data (which would be Destructive), execute arbitrary code (Execute), or move money (Financial). The medium severity reflects that misuse could alter task details, priority, or status across potentially many tasks, but the impact is recoverable through subsequent updates.
From the tool's definition Tool name 'todoist_update_task' and description 'Update an existing task by its ID' indicate modification of existing data. The action is reversible (can be updated again to previous state), distinguishing it from destructive operations.

PolicyLayer is an MCP gateway — it sits between your AI agents and Enhanced Todoist MCP Server Extended, and nothing reaches the server without passing your rules. This is the rule we recommend for todoist_update_task:
{
"version": "1",
"default": "deny",
"tools": {
"todoist_update_task": {
"limits": [
{
"counter": "todoist_update_task_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
} todoist_update_task 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.
