Frequently Asked Questions
How do I connect JavaScript Sandbox to my app?
JavaScript Sandbox does not require an external account connection. Install the SDK, add the integration to a workspace, then execute tools programmatically.
What tools does JavaScript Sandbox support?
JavaScript Sandbox supports 1 tools including Run Code.
Can I use JavaScript Sandbox with AI agents?
Yes. Add JavaScript Sandbox to an MCP server in Tool Mode or Code Mode. Code Mode provides 3 meta-tools with on-demand API discovery so agents can compose stateful workflows without loading every action schema up front.
How do I connect JavaScript Sandbox to ChatGPT or Claude?
Open the Weavz connector setup, sign in, choose a workspace, and add JavaScript Sandbox as an approved app. ChatGPT, Claude, and other remote MCP clients can then call the scoped JavaScript Sandbox tools exposed by that workspace.
Does JavaScript Sandbox work with Claude Code, Cursor, Codex, and local agents?
Yes. Remote and local MCP clients can connect to a Weavz MCP endpoint for the workspace. Local coding agents can also use the Weavz CLI to inspect apps, discover actions, run approved JavaScript Sandbox work, and execute Code Mode workflows from a terminal.
What can I ask an AI agent to do with JavaScript Sandbox?
JavaScript Sandbox exposes 1 tools, including Run Code. Use Weavz to keep credentials scoped, require approval for sensitive work, and audit what the agent did.
Can JavaScript Sandbox be used in stateful agent workflows?
