MultiversX Cryptographic Profile Manager (MCP) Service

This repository describes an MCP server engineered specifically for interaction with the MultiversX distributed ledger technology. It encapsulates core cryptographic and transaction management capabilities, such as generating PEM-formatted keystores, resolving public account identifiers, querying current asset holdings, and submitting transactions for various digital assets (EGLD, ESDT, SFT, NFT, MetaESDT).

Core Features Overview

Keystore Initialization: Generates a new PEM-based wallet file, conventionally stored at: ~/.multiversx/wallet.pem.
Network Context Retrieval: Fetches the currently configured operational network environment.
Identifier Extraction: Retrieves the associated public address derived from the active configuration.
Asset Status Query: Fetches the balance summary for any given ledger address.
Transaction Submission: Facilitates the dispatch of token transfers.
Asset Provisioning: Supports the process of issuing new token standards.

Integration with Claude Desktop Environments

To incorporate this service into your local Claude Desktop setup, please ensure you have the client application installed.

Locate or create the necessary configuration file:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows: %APPDATA%\Claude\claude_desktop_config.json
Linux: ~/.config/Claude/claude_desktop_config.json

Inject the following JSON structure into the mcpServers block:

{ "mcpServers": { "multiversx-mcp": { "command": "npx", "args": [ "-y", "@multiversx/mcp" ], "env": { "MVX_NETWORK": "devnet", "MVX_WALLET": "absolute/path/to/someWallet.pem" } } } }

Integration with Cursor IDE

The preceding JSON configuration is directly compatible with Cursor (version 0.47 and later). Place this configuration within ~/.cursor/mcp.json, or utilize the integrated settings pane under the MCP section to manually add a new server definition.

Compiling from Source Code

To build the utility from its source repository:

Clone the repository content.
Execute the build script: npm run build.

Subsequently, update your configuration file to point to the newly compiled executable:

{ "mcpServers": { "multiversx-mcp": { "command": "node", "args": [ "absolute/path/to/index.js" ], "env": { "MVX_NETWORK": "devnet", "MVX_WALLET": "absolute/path/to/someWallet.pem" } } } }
