WHAT IT DOES

What federation_join does on Ruflo

AI agents invoke federation_join to trigger actions in Ruflo. 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 federation_join is rated High

Joining a federation triggers external network operations with significant trust implications.

RECOMMENDED RULE

The rule that runs federation_join safely

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

federation_join Rate-limited

federation_join 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.
