Questions about x_federation_channel_publish
Publish a message to a channel with YOUR OWN key. A private channel is encrypted locally under its channel key before it leaves this machine, and the message type is hidden behind k=enc so the relay sees only an opaque id and ciphertext. Use when the message should be attributable to you. The admin-gated gateway channel_publish is wrong for that, because it signs as the gateway and cannot reach private channels at all. It is categorised as a Write tool in the Ruflo MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Ruflo MCP server in PolicyLayer and add a rule for x_federation_channel_publish: 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 Ruflo. Nothing to install.
