WHAT IT DOES

What chat_with_agent does on ProAgentStore

AI agents invoke chat_with_agent to trigger actions in ProAgentStore. 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 chat_with_agent is rated High

Sending a message to a published agent initiates external operations whose effects depend on the message arguments passed. The agent may perform reads, writes, or other side-effectful actions depending on its capabilities. This is an Execute-level action because it triggers an external operation (agent execution) with unpredictable downstream effects.

From the tool's definition "Send a message to a published agent (trial mode)" — triggers execution of an external agent with arbitrary message input

RECOMMENDED RULE

The rule that runs chat_with_agent safely

PolicyLayer is an MCP gateway: it sits between your AI agents and ProAgentStore, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For chat_with_agent, this is the rule to start with:

chat_with_agent Rate-limited

chat_with_agent 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.
