WHAT IT DOES

What wasm_optimize does on Jshookmcp

AI agents invoke wasm_optimize to trigger actions in Jshookmcp. 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_optimize is rated High

Processes and transforms a binary file, executing optimization operations on it.

RECOMMENDED RULE

The rule that runs wasm_optimize safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Jshookmcp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For wasm_optimize, this is the rule to start with:

wasm_optimize Rate-limited

wasm_optimize 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.

The button opens the PolicyLayer dashboard: create your workspace, connect Jshookmcp, apply this rule, and every wasm_optimize call is checked against it from then on.

FAQ

Questions about wasm_optimize

What does the wasm_optimize tool do? +

Optimize a .wasm binary for size or speed. It is categorised as a Execute tool in the Jshookmcp 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_optimize? +

Register the Jshook MCP server in PolicyLayer and add a rule for wasm_optimize: 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 Jshookmcp. Nothing to install.

What risk level is wasm_optimize? +

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

Can I rate-limit wasm_optimize? +

Yes. Add a rate_limit block to the wasm_optimize 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_optimize completely? +

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

wasm_optimize is provided by the Jshook MCP server (@jshookmcp/jshook). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
