wasm_gallery_configure · Ruflo MCP: Risk & Policy

WHAT IT DOES

What wasm_gallery_configure does on Ruflo

AI agents use wasm_gallery_configure 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.

WHY IT NEEDS A POLICY

Why wasm_gallery_configure needs a policy

This is a Write operation because it modifies configuration settings (maxTurns, model, etc.) in the active WASM runtime state. While the changes are reversible (overrides can be replaced or reverted), the severity is high because misconfiguring a WASM gallery template could disrupt agent operations, affect model behavior across swarm instances, or cause cascading failures in multi-agent workflows.

From the tool's definition Tool applies 'runtime configuration overrides' to 'active WASM gallery template'; modifies state in the WASM runtime rather than filesystem. The term 'configure' and 'apply overrides' indicate write operations that alter active system configuration.

Verdict

wasm_gallery_configure Rate-limited

wasm_gallery_configure stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches Ruflo, so you can run agents against it safely.

FAQ

Questions about wasm_gallery_configure

What does the wasm_gallery_configure tool do? +

Apply runtime configuration overrides (e.g. maxTurns, model) to the active WASM gallery template. Use when native Edit is wrong because gallery configuration lives inside the WASM runtime state and cannot be changed via filesystem writes. 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.

How do I enforce a policy on wasm_gallery_configure? +

Register the Ruflo MCP server in PolicyLayer and add a rule for wasm_gallery_configure: 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.

What risk level is wasm_gallery_configure? +

wasm_gallery_configure is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit wasm_gallery_configure? +

Yes. Add a rate_limit block to the wasm_gallery_configure 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_configure completely? +

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

wasm_gallery_configure 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.
