run_watch · TalkDB MCP: Risk & Policy

WHAT IT DOES

What run_watch does on TalkDB

AI agents invoke run_watch to trigger actions in TalkDB. 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.

WHY IT NEEDS A POLICY

Why run_watch needs a policy

This tool executes a watch/alert mechanism whose effects depend on the watch's configuration and the underlying data state. While it does not directly delete data or move money, it triggers external operations (alerts, notifications) whose consequences are not immediately reversible and depend on how alerts are configured downstream. This makes it Execute rather than Write or Read.

From the tool's definition Tool 'run_watch' description states it 'Manually execute a watch now', which triggers execution of a scheduled query/alert system.

Verdict

run_watch Rate-limited

run_watch 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.

Register the TalkDB MCP server in PolicyLayer and add a rule for run_watch: 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 TalkDB. Nothing to install.

What risk level is run_watch? +

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

Can I rate-limit run_watch? +

Yes. Add a rate_limit block to the run_watch 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 run_watch completely? +

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