XRP Ledger Model Context Protocol Server

License: MIT | XRPL Networks | TypeScript | xrpl.js

A comprehensive Model Context Protocol (MCP) server that provides blockchain services for the XRP Ledger ecosystem. This server enables AI agents to interact with XRPL MainNet, TestNet, and DevNet with a unified interface.

🔭 Overview

The MCP XRPL Server leverages the Model Context Protocol to provide XRP Ledger services to AI agents. It supports a wide range of services including:

Reading ledger state (balances, transactions, account info, etc.)
Interacting with smart contracts (via Hooks)
Transferring XRP and issued tokens
Querying token metadata and balances
Managing decentralized identifiers (DIDs)
Working with NFTs on the XRPL
Automated Market Maker (AMM) operations
Payment channels, escrows, and checks
Oracle data operations
Trustline management

All services are exposed through a consistent interface of MCP tools and resources, making it easy for AI agents to discover and use XRPL functionality.

Resources

The server exposes XRPL data through the following MCP resource URIs:

Ledger Resources

Resource URI Pattern	Description
`xrpl://{network}/ledger/current`	Current ledger information
`xrpl://{network}/ledger/{ledger_index}`	Ledger by index
`xrpl://{network}/account/{address}`	Account information

🔒 Security Considerations

Wallet seeds are used only for transaction signing and should be kept secure
Consider implementing additional authentication mechanisms for production use
For high-value services, consider adding confirmation steps
Default operations are performed on TestNet to ensure safety during development
Use environment variables for sensitive configuration
