AI agents use federation_wg_attest to create or update resources in Ruflo — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Ruflo environment.
The tool writes a signed attestation entry to a log file. It creates/appends data to a persistent log, which is a reversible write operation. While it involves federation coordination and signing (suggesting some sensitivity), it is explicitly idempotent and appends to a log rather than executing commands or destroying data.
From the tool's definition emit an operator-signed attestation entry for a coordination change... operator appends it to .claude-flow/federation/wg-changes.log. Idempotent — re-attesting the same change just appends another entry

ADR-111 Phase 6 (witness chain): emit an operator-signed attestation entry for a coordination change. Returns the canonical bytes the operator signs + the witness entry; operator appends it to .claude-flow/federation/wg-changes.log. Idempotent — re-attesting the same change just appends another entry. 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 federation_wg_attest: 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.
federation_wg_attest is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the federation_wg_attest 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.
Set action: deny in the PolicyLayer policy for federation_wg_attest. 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.
federation_wg_attest 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.
federation_wg_attest is one line of Ruflo's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
