Abstraxn Agent Layer MCP Server

A free, public MCP (Model Context Protocol) server for Web3 data. Point any MCP client - Claude Desktop, Cursor, your own agent - at it and it can read live chain data (block height, gas, transaction status, ERC-20 info, spot prices), look up weather forecasts, build unsigned EVM/Solana transfer transactions, and, for a handful of pay-per-call tools, look up market data, wallets/tokens/ENS, travel search…. Its 12 documented tools cover network, info, token. It is available as a remote MCP endpoint.

Teams that want a hosted endpoint instead of running a local process. The project is written in TypeScript.

before you install - you'll need

The README does not document required environment variables for a basic install.

Claude Code

claude mcp add abstraxn-labs-abstraxn-agent-layer --transport http https://mcp.abstraxn.com/mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "abstraxn-labs-abstraxn-agent-layer": {
      "url": "https://mcp.abstraxn.com/mcp"
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key
