WHAT IT DOES

What connect does on Ncp

AI agents invoke connect to trigger actions in Ncp. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why connect is rated High

Establishing a database connection is an active operation that initiates an external session/resource, going beyond a simple read. It triggers an external operation (opening a persistent connection to a MySQL database) whose effects depend on arguments (credentials, host, etc.). Misuse could expose database access, enable subsequent destructive queries, or leak credentials.

RECOMMENDED RULE

The rule that runs connect safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Ncp, 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 rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

The button opens the PolicyLayer dashboard: create your workspace, connect Ncp, apply this rule, and every connect call is checked against it from then on.

FAQ

Questions about connect

What does the connect tool do? +

Connect to mysql-api database. It is categorised as a Execute tool in the Ncp MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on connect? +

Register the Ncp 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 Ncp. Nothing to install.

What risk level is connect? +

connect is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit connect? +

Yes. Add a rate_limit block to the connect 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.

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? +

connect is provided by the Ncp MCP server (@portel/ncp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
