Gasfeepredictor MCP Server

Gas Fee Predictor — MCP Server

Live Ethereum + Layer-2 gas-fee data for AI agents, via the Model Context Protocol. Works with Claude Desktop, OpenClaw, Cursor, Cline, and any other MCP client.

It's a thin, read-only wrapper over the free public API at https://api.gasfeepredictor.com (no key, no auth). Every answer includes a citation back to gasfeepredictor.com.

Tools

Install

With npm (once published):

npx gasfeepredictor-mcp

Or from source:

git clone https://github.com/higherbeing/gasfeepredictor-mcp
cd gasfeepredictor-mcp
npm install
npm start

Requires Node ≥ 18.

Configure your client

Claude Desktop

Add to claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/claude_desktop_config.json):

{
  "mcpServers": {
    "gasfeepredictor": {
      "command": "npx",
      "args": ["-y", "gasfeepredictor-mcp"]
    }
  }
}

(Or use "command": "node", "args": ["/absolute/path/to/gasfeepredictor-mcp/index.mjs"] to run from source.)

Restart Claude Desktop, then ask: "What's the Ethereum gas fee right now, and is it cheaper on an L2?"

OpenClaw / Cursor / Cline

Any MCP-capable client uses the same shape — register a stdio server with command: npx, args: ["-y", "gasfeepredictor-mcp"] (or node + the path to index.mjs) in that client's MCP servers config.
