Grants relay membership to a cryptographic identity, a privileged access-control write action.

From the tool's definition Admit a Nostr pubkey as a relay member directly

RECOMMENDED RULE

The rule that runs x_federation_admit safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Claude Flow, 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 Claude Flow 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 Claude Flow 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 Claude Flow. 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 Claude Flow MCP server (claude-flow). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
