RECOMMENDED RULE

The rule that runs x_federation_admit 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 x_federation_admit, this is the rule to start with:

x_federation_admit Rate-limited

x_federation_admit stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about x_federation_admit

What does the x_federation_admit tool do? +

Admit a Nostr pubkey as a relay member directly (NIP-43 kind 9030). Requires RUFLO_X_ADMIN_TOKEN. Use when a known node reports its 64-hex pubkey and you want to skip the invite step. Padding or hand-editing a reported pubkey is wrong because it is a cryptographic identity; a malformed key must be re-reported, never fixed up. 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.

How do I enforce a policy on x_federation_admit? +

Register the Ruflo MCP server in PolicyLayer and add a rule for x_federation_admit: 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.

What risk level is x_federation_admit? +

x_federation_admit is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit x_federation_admit? +

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

Set action: deny in the PolicyLayer policy for x_federation_admit. 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 x_federation_admit? +

x_federation_admit is provided by the Ruflo MCP server (ruvnet/ruflo). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
