# update_startup_script A write tool on the Vultr MCP MCP server. Agent View of the PolicyLayer registry record for `update_startup_script`. HTML page: https://policylayer.com/tools/rsp2k-mcp-vultr/update-startup-script ## Facts - Tool: `update_startup_script` - Server: Vultr MCP (`rsp2k/mcp-vultr`) — https://policylayer.com/tools/rsp2k-mcp-vultr.md - Homepage: https://github.com/rsp2k/mcp-vultr - Risk category: Write (Medium 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": "update_startup_script", "arguments": {} } } ``` ## Why update_startup_script is rated Medium Startup scripts execute arbitrary code at instance initialization. Modifying them could alter system behavior, install malicious software, or compromise instance security. However, since updates are reversible (old versions can be restored), this is Write rather than Execute or Destructive. High severity due to the wide-ranging implications of startup script changes across potentially many instances. Confidence is 0. From the tool's own definition: "Tool name 'update_startup_script' indicates modification of startup scripts, which are configuration files that execute when instances boot. The verb 'update' confirms reversible modification rather than deletion." ## Use case AI agents use update_startup_script to create or update resources in Vultr MCP, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Vultr MCP environment. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**.
