WHAT IT DOES

What wasm_agent_list does on Claude Flow

AI agents call wasm_agent_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 wasm_agent_list is rated Low

This tool queries and enumerates the state of active WASM agents in the system. While it operates in the context of an orchestration system managing untrusted code execution, the tool itself only retrieves information about agents; it does not create, modify, terminate, or execute agents (those are separate tools: wasm_agent_create, agent_terminate, agent_spawn).

From the tool's definition Tool name contains 'list' and description states 'List all active WASM agents' — a retrieval operation with no modification, deletion, or code execution capability.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

wasm_agent_list Allowed

wasm_agent_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": {
    "wasm_agent_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 wasm_agent_list call is checked against it from then on.

FAQ

Questions about wasm_agent_list

What does the wasm_agent_list tool do? +

List all active WASM agents. Use when native Task is wrong because the workload needs sandboxed isolation — untrusted code execution, browser-side run, deterministic replay. Pair with wasm_gallery_search to find a published agent, or wasm_agent_create to scaffold a fresh one. For trusted in-process work, native Task is fine. 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 wasm_agent_list? +

Register the Claude Flow MCP server in PolicyLayer and add a rule for wasm_agent_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 wasm_agent_list? +

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

Can I rate-limit wasm_agent_list? +

Yes. Add a rate_limit block to the wasm_agent_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 wasm_agent_list completely? +

Set action: deny in the PolicyLayer policy for wasm_agent_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 wasm_agent_list? +

wasm_agent_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.
