DevX Multichain Balances MCP

An MCP server that retrieves native coin and major token balances (USDC, USDT, DAI, WETH, WBTC, etc.) across 7 EVM chains, Solana, and Tron. It supports free single-chain lookups and paid multi-chain queries via x402, enabling AI agents to check wallet holdings without managing RPC infrastructure.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.

Claude Code configuration

claude mcp add --transport http devx-multichain-balances-mcp-workers https://wallet-balances.nextill-pos.workers.dev/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).

Codex configuration

codex mcp add devx-multichain-balances-mcp-workers --url https://wallet-balances.nextill-pos.workers.dev/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable devx-multichain-balances-mcp-workers in your MCP settings.
