WHAT IT DOES

What connect does on DG-MCP

AI agents use connect 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.

RISK

Why connect is rated Medium

An AI agent can call connect 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

RECOMMENDED RULE

The rule that runs connect 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 connect, this is the rule to start with:

connect Rate-limited

connect 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.

连接到指定的 DG-Lab 设备。需先调用 scan 获取地址。可多次调用以连接多台不同设备；对已连接地址重复调用会报错。. 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.

How do I enforce a policy on connect? +

Register the DG MCP server in PolicyLayer and add a rule for connect: 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.

What risk level is connect? +

connect is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit connect? +

How do I block connect completely? +

Set action: deny in the PolicyLayer policy for connect. 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.

What MCP server provides connect? +
