WHAT IT DOES

What delete_model does on MCP Trader Server

AI agents call delete_model to permanently remove resources in MCP Trader Server, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

RISK

Why delete_model is rated Critical

Deletion of ML models constitutes irreversible destruction of computational assets. While not directly financial, the loss of a trained model represents significant operational and potentially financial impact (retraining costs, lost trading signals if model was in use). In the context of a trading server, deleting an active model could disrupt automated trading operations.

From the tool's definition Tool name is 'delete_model' and description states 'Delete a model from Ollama' — explicit use of the word 'Delete' indicates irreversible removal of data/resources.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs delete_model safely

PolicyLayer is an MCP gateway: it sits between your AI agents and MCP Trader Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For delete_model, this is the rule to start with:

delete_model Hidden

delete_model 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 MCP Trader Server, apply this rule, and every delete_model call is checked against it from then on.
