Check or uncheck a checkbox element. Works with both <input type=
AI agents invoke checkbox_set to trigger actions in MCP Playwright Server. 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.
This tool performs a browser action (checking/unchecking a checkbox) that modifies the state of a web page element. It's an interactive browser automation action that could trigger form submissions, enable/disable features, or change application settings depending on the target checkbox. This falls under Execute as it performs external browser operations whose effects depend on the arguments provided.
From the tool's definition 'Check or uncheck a checkbox element' — triggers browser interaction via Playwright automation to manipulate UI state
Attacks that exploit this kind of access
Check or uncheck a checkbox element. Works with both <input type=. It is categorised as a Execute tool in the MCP Playwright Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the MCP Playwright Server MCP server in PolicyLayer and add a rule for checkbox_set: 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 MCP Playwright Server. Nothing to install.
checkbox_set is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the checkbox_set 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 checkbox_set. 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.
checkbox_set is provided by the MCP Playwright Server MCP server (j0hanz/playwright-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
checkbox_set is one line of MCP Playwright Server's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
