# timers_start Start a specific timer Agent View of the PolicyLayer registry record for `timers_start`. HTML page: https://policylayer.com/tools/io-github-alxpark-propresenter-mcp/timers-start ## Facts - Tool: `timers_start` - Server: Propresenter (`@alxpark/propresenter-mcp`) — https://policylayer.com/tools/io-github-alxpark-propresenter-mcp.md - Install: `npx -y @alxpark/propresenter-mcp` - Homepage: https://github.com/alxpark/propresenter-mcp - Risk category: Execute (High risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Rate-limited ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "timers_start", "arguments": {} } } ``` ## Why timers_start is rated High The tool executes a command that initiates a timer in an external application, which is an operational side effect. It is not a simple read operation (no data retrieval), nor is it destructive or financial. It falls under Execute because it triggers an external operation whose actual impact depends on the arguments provided (which specific timer, and what that timer controls in the presentation context). From the tool's own definition: "Tool name 'timers_start' and description 'Start a specific timer' indicate this triggers an external operation (timer activation) on ProPresenter 7, which is an audio/visual presentation software." ## Use case AI agents invoke timers_start to trigger actions in Propresenter. 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. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**.
