Type text into input fields, text areas, or focused elements. Set clear=True to replace existing text, False to append. Click on target element coordinates first.
AI agents invoke Type-Tool to trigger actions in Windows-MCP. 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.
The Type-Tool injects keystrokes into active Windows UI elements. While typing alone is not inherently destructive, it can trigger form submissions, issue commands, modify application state, or interact with any focused element—including terminals or search fields. The effects depend entirely on the target element and content typed, making it an Execute-category tool.
From the tool's definition Type text into input fields, text areas, or focused elements. Set clear=True to replace existing text, False to append.
Attacks that exploit this kind of access
Type text into input fields, text areas, or focused elements. Set clear=True to replace existing text, False to append. Click on target element coordinates first. It is categorised as a Execute tool in the Windows-MCP MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Windows- MCP server in PolicyLayer and add a rule for Type-Tool: 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 Windows-MCP. Nothing to install.
Type-Tool 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 Type-Tool 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 Type-Tool. 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.
Type-Tool is provided by the Windows- MCP server (stepbystep-1/winows-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
