What federation_bbs_human_join does on Claude Flow
AI agents call federation_bbs_human_join 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.
Why federation_bbs_human_join is rated Low
Even though federation_bbs_human_join only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

The rule that runs federation_bbs_human_join 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 federation_bbs_human_join, this is the rule to start with:
federation_bbs_human_join is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Claude Flow, apply this rule, and every federation_bbs_human_join call is checked against it from then on.
Questions about federation_bbs_human_join
agentbbs — Mint a single-use Ed25519-signed token a human business owner presents to the agentbbs SSH/web front door to join a room (ADR-164 §3.2.4). Returns webUrl + sshCommand + handshakeToken + expiresAt. Use when the cockpit operator needs scoped, time-limited access to a room without sharing the federation root keypair. Issuing a permanent bearer token is wrong because the agentbbs server enforces single-use JTI replay protection and the 15-min default TTL — a long-lived token defeats both. Optional dep — degrades to {degraded:true} when missing. It is categorised as a Read tool in the Claude Flow MCP Server, which means it retrieves data without modifying state.
Register the Claude Flow MCP server in PolicyLayer and add a rule for federation_bbs_human_join: 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.
federation_bbs_human_join is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the federation_bbs_human_join 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.
