Gexno Web3 MCP

A community MCP server providing free, read-only Ethereum wallet profile and NFT metadata lookup tools for AI agents. It supports remote HTTP access without installation or API keys, as well as local stdio execution via npm. The server offers simple risk heuristics and metadata retrieval for ERC-721 and ERC-1155 tokens.

Endpoint and access

lookup_wallet

Advertised by the server during the last successful anonymous check.

Advertised read-onlyOpen-world

Look up an Ethereum wallet: ETH balance, contract flag, outbound tx count, and simple risk heuristics (ok / new_wallet / contract / eip7702). EIP-7702 delegated EOAs report risk=eip7702. Read-only; not an AML score.

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 gexno-web3-mcp https://api.gexno.com/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 gexno-web3-mcp --url https://api.gexno.com/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable gexno-web3-mcp in your MCP settings.

Cursor configuration

{
  "mcpServers": {
    "gexno-web3-mcp": {
      "url": "https://api.gexno.com/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).

Cline configuration

{
  "mcpServers": {
    "gexno-web3-mcp": {
      "type": "streamableHttp",
      "url": "https://api.gexno.com/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start gexno-web3-mcp and inspect its tools.

VS Code configuration

{
  "servers": {
    "gexno-web3-mcp": {
      "type": "http",
      "url": "https://api.gexno.com/mcp"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.

Gemini CLI configuration

gemini mcp add --transport http gexno-web3-mcp https://api.gexno.com/mcp

Claude Desktop

Merge this into claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\), then restart Claude Desktop.

Claude Desktop configuration

{
  "mcpServers": {
    "gexno-web3-mcp": {
      "url": "https://api.gexno.com/mcp"
    }
  }
}

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.

Windsurf configuration

{
  "mcpServers": {
    "gexno-web3-mcp": {
      "serverUrl": "https://api.gexno.com/mcp"
    }
  }
}
