ui_form_snapshot
AI agents call ui_form_snapshot to retrieve information from UI Bridge MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
A snapshot operation retrieves UI state without modifying or executing actions on forms. It aligns with the Read category for data retrieval with no side effects. Severity is low because inspecting UI state poses minimal risk even if misused by an agent.
From the tool's definition Tool name 'ui_form_snapshot' suggests capturing a static screenshot or snapshot of UI form state. Sibling tools like 'get_idle_status', 'sdk_annotated_screenshot', and 'sdk_analyze_*' reinforce that this server emphasizes inspection and analysis rather than…

ui_form_snapshot. It is categorised as a Read tool in the UI Bridge MCP MCP Server, which means it retrieves data without modifying state.
Register the UI Bridge MCP server in PolicyLayer and add a rule for ui_form_snapshot: 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 UI Bridge MCP. Nothing to install.
ui_form_snapshot 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 ui_form_snapshot 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 ui_form_snapshot. 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.
ui_form_snapshot is provided by the UI Bridge MCP server (qontinui/ui-bridge-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
