What disconnect does on DG-MCP
AI agents use disconnect to create or update resources in DG-MCP, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your DG-MCP environment.
Why disconnect is rated Medium
An AI agent can call disconnect faster than any human can review: one bad instruction and it creates or modifies resources in DG-MCP by the hundred, each call as confident as the last.
Attacks that exploit this kind of access
The rule that runs disconnect safely
PolicyLayer is an MCP gateway: it sits between your AI agents and DG-MCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For disconnect, this is the rule to start with:
disconnect 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.
The button opens the PolicyLayer dashboard: create your workspace, connect DG-MCP, apply this rule, and every disconnect call is checked against it from then on.
Questions about disconnect
断开设备连接。指定 address 则只断开该设备,省略则断开全部已连接设备。. It is categorised as a Write tool in the DG-MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the DG MCP server in PolicyLayer and add a rule for disconnect: 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 DG-MCP. Nothing to install.
disconnect 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 disconnect 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 disconnect. 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.
disconnect is provided by the DG MCP server (0xnullai/dg-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
