start_monitor

Start the BetterDB monitor as a persistent background process. If already running, returns the existing URL. The monitor persists across MCP sessions and must be stopped explicitly with stop_monitor.

Part of the Betterdb MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.

@betterdb/mcp Execute Risk 3/5

AI agents invoke start_monitor to trigger processes or run actions in Betterdb. Execute operations can have side effects beyond the immediate call -- triggering builds, sending notifications, or starting workflows. Rate limits and argument validation are essential to prevent runaway execution.

start_monitor can trigger processes with real-world consequences. An uncontrolled agent might start dozens of builds, send mass notifications, or kick off expensive compute jobs. Intercept enforces rate limits and validates arguments to keep execution within safe bounds.

Execute tools trigger processes. Rate-limit and validate arguments to prevent unintended side effects.

What does the start_monitor tool do? +

Start the BetterDB monitor as a persistent background process. If already running, returns the existing URL. The monitor persists across MCP sessions and must be stopped explicitly with stop_monitor.. It is categorised as a Execute tool in the Betterdb MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on start_monitor? +

Add a rule in your Intercept YAML policy under the tools section for start_monitor. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Betterdb MCP server.

What risk level is start_monitor? +

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

Can I rate-limit start_monitor? +

Yes. Add a rate_limit block to the start_monitor rule in your Intercept 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 start_monitor completely? +

Set action: deny in the Intercept policy for start_monitor. 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 start_monitor? +

start_monitor is provided by the Betterdb MCP server (@betterdb/mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
