Capture a screenshot of a web page and return a hosted URL to the image.
AI agents call screenshot to retrieve information from ToolCenter MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool reads/renders a web page and returns a URL to a screenshot image. It does not modify, delete, or execute anything with side effects. It is purely a read/capture operation, though it does host the image externally, which is a minor side effect but does not reach the Write threshold in a meaningful way for misuse risk.

Attacks that exploit this kind of access
Capture a screenshot of a web page and return a hosted URL to the image. It is categorised as a Read tool in the ToolCenter MCP MCP Server, which means it retrieves data without modifying state.
Register the ToolCenter MCP server in PolicyLayer and add a rule for screenshot: 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 ToolCenter MCP. Nothing to install.
screenshot 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 screenshot 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 screenshot. 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.
screenshot is provided by the ToolCenter MCP server (toolcenter-dev/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
