# permissioned-domain-set Create or modify a Permissioned Domain on the XRP Ledger. Permissioned Domains define access rules based on credentials, allowing only authorized accounts (those with accepted credentials from specified issuers) to participate in certain activities. Agent View of the PolicyLayer registry record for `permissioned-domain-set`. HTML page: https://policylayer.com/tools/romthpt-mcp-xrpl/permissioned-domain-set ## Facts - Tool: `permissioned-domain-set` - Server: Xrpl mcp (`romthpt/mcp-xrpl`) — https://policylayer.com/tools/romthpt-mcp-xrpl.md - Homepage: https://github.com/RomThpt/mcp-xrpl - 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": "permissioned-domain-set", "arguments": {} } } ``` ## Why permissioned-domain-set is rated Medium The tool creates or modifies access control configurations (Permissioned Domains) on the XRP Ledger. While Write is the appropriate category (reversible modification of ledger state), severity is elevated to 'high' because misconfiguration or unauthorized domain creation/modification could restrict legitimate account access, lock users out of activities, or grant unintended permissions to malicious issuers, creating… From the tool's own definition: "Tool description states 'Create or modify a Permissioned Domain on the XRP Ledger' - 'create or modify' indicates reversible data creation/modification operations on blockchain state." ## Use case AI agents use permissioned-domain-set to create or update resources in Xrpl mcp, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Xrpl mcp environment. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**.
