What deleteOneTask does on Twenty MCP Server
AI agents call deleteOneTask to permanently remove resources in Twenty MCP Server, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Why deleteOneTask is rated Critical
The tool permanently deletes a task record with no indication of reversibility or undo capability. This is a destructive operation that cannot be recovered without external backups. While the impact is scoped to a single task (reducing blast radius compared to bulk deletion), the irreversible nature and lack of recovery mechanism classify it as Destructive rather than Write.
From the tool's definition Tool name 'deleteOneTask' with description 'Delete One task' explicitly uses the delete verb, which irreversibly removes data from the CRM system.
Attacks that exploit this kind of access
The rule that runs deleteOneTask safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Twenty MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For deleteOneTask, this is the rule to start with:
deleteOneTask is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
The button opens the PolicyLayer dashboard: create your workspace, connect Twenty MCP Server, apply this rule, and every deleteOneTask call is checked against it from then on.
