HTML page: https://policylayer.com/tools/trekmail-mcp-server/update-domain-note ## Facts - Tool: `update_domain_note` - Server: TrekMail MCP Server (`trekmail/mcp-server`) — https://policylayer.com/tools/trekmail-mcp-server.md - Homepage: https://github.com/trekmail/mcp-server - 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_domain_note", "arguments": {} } } ``` ## Why update_domain_note is rated Medium This tool creates or modifies domain metadata (notes/descriptions) in a reversible manner. It does not delete data irreversibly, execute code, move money, or trigger external operations. The blast radius of misuse is minimal since updating domain notes cannot corrupt infrastructure or cause service disruption. Classified as Write rather than Read because it performs a modification operation, not just retrieval. From the tool's own definition: "Tool description states 'Update the note/description on a domain' - this modifies metadata on an existing domain resource. The ability to pass null to clear the field confirms reversible modification capability." ## Use case AI agents use update_domain_note to create or update resources in TrekMail MCP Server, usually the action step of a workflow, after the agent has gathered context.
