AI agents call workspace_web_apps to retrieve information from Yaver without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
kind | string | — | Comma-separated kinds to keep (web,hybrid,mobile). Defaults to web,hybrid. |
root | string | — | Repo root. Defaults to agent CWD. |
Parameters from the server's own tool schema.
Even though workspace_web_apps only reads data, uncontrolled read access leaks sensitive information and racks up API costs — an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
Attacks that exploit this kind of access
Return workspace apps whose stack maps to a web surface (nextjs, vite, flutter, react-native-expo). Used by the Web Reload dashboard tab to populate its app picker. It is categorised as a Read tool in the Yaver MCP Server, which means it retrieves data without modifying state.
workspace_web_apps accepts 2 parameters: kind, root. The full parameter table on this page comes from the server's own tool schema.
Register the Yaver MCP server in PolicyLayer and add a rule for workspace_web_apps: 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 Yaver. Nothing to install.
workspace_web_apps is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the workspace_web_apps 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.
Set action: deny in the PolicyLayer policy for workspace_web_apps. 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.
workspace_web_apps is provided by the Yaver MCP server (yaver-cli). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
