WHAT IT DOES

What wasm_gallery_create does on Claude Flow

AI agents invoke wasm_gallery_create to trigger actions in Claude Flow. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why wasm_gallery_create is rated High

This tool instantiates and runs WASM-based agents capable of executing untrusted code in a sandboxed environment. The explicit mention of 'untrusted code execution' and spawning agents that run workloads makes this an Execute-category tool.

From the tool's definition 'Create a WASM agent from a gallery template' and 'sandboxed isolation — untrusted code execution, browser-side run, deterministic replay'

Attacks that exploit this kind of access

RECOMMENDED RULE

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

wasm_gallery_create Rate-limited

wasm_gallery_create stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "wasm_gallery_create": {
      "limits": [
        {
          "counter": "wasm_gallery_create_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

RATE-LIMIT 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_gallery_create call is checked against it from then on.

FAQ

Questions about wasm_gallery_create

What does the wasm_gallery_create tool do? +

Create a WASM agent from a gallery template. 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 Execute tool in the Claude Flow MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on wasm_gallery_create? +

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

wasm_gallery_create is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit wasm_gallery_create? +

Yes. Add a rate_limit block to the wasm_gallery_create 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_gallery_create completely? +

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

wasm_gallery_create 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.
