WHAT IT DOES

What channel_list does on Claude Flow

AI agents call channel_list 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 channel_list is rated Low

Tool retrieves metadata about channels without modification or execution of operations.

From the tool's definition Lists recently observed swarm channels with visibility, message count, publisher count

RECOMMENDED RULE

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

channel_list Allowed

channel_list 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": {
    "channel_list": {}
  }
}

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 channel_list call is checked against it from then on.

FAQ

Questions about channel_list

What does the channel_list tool do? +

Lists recently observed swarm channels with visibility, message count, publisher count, and purpose. Public channel ids contain their name (pub:<name>); private ids are opaque (prv:<hex>) and reveal no topic. Well-known public channels are included even when quiet. 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 channel_list? +

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

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

Can I rate-limit channel_list? +

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

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

channel_list 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.
