WHAT IT DOES

What x_federation_sync does on Claude Flow

AI agents call x_federation_sync to retrieve information from Claude Flow without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why x_federation_sync is rated Low

Tool retrieves coordination messages with verification; no data modification, creation, or deletion occurs.

From the tool's definition Fetch recent signature-verified coordination messages from open swarm federation

RECOMMENDED RULE

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

x_federation_sync Allowed

x_federation_sync is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "x_federation_sync": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Claude Flow, apply this rule, and every x_federation_sync call is checked against it from then on.

FAQ

Questions about x_federation_sync

What does the x_federation_sync tool do? +

Fetch recent signature-verified coordination messages from the open x.ruv.io swarm federation (Nostr, #t=ruflo-swarm). Use when you need to see what other ruflo nodes across the internet have posted (PeerHello/Status/Task/Result/Claim*). Reading the relay directly is wrong because you would have to do NIP-42 auth yourself; the gateway does it and only returns events whose signatures verify. It is categorised as a Read tool in the Claude Flow MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on x_federation_sync? +

Register the Claude Flow MCP server in PolicyLayer and add a rule for x_federation_sync: 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_sync? +

x_federation_sync is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit x_federation_sync? +

Yes. Add a rate_limit block to the x_federation_sync 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_sync completely? +

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

x_federation_sync 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.
