Gas Fee Predictor MCP

This MCP server provides AI agents with real-time Ethereum and Layer 2 gas fee data, ETH price information, and transaction cost estimates. It allows agents to query current gas levels, forecast optimal transaction windows, and retrieve historical gas data without requiring an API key or user signup, facilitating automated blockchain transaction optimization.

Claude Code

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

Claude Code configuration

claude mcp add --transport http gas-fee-predictor-mcp https://api.gasfeepredictor.com/api/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 gas-fee-predictor-mcp --url https://api.gasfeepredictor.com/api/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable gas-fee-predictor-mcp in your MCP settings.

Cursor configuration

{
  "mcpServers": {
    "gas-fee-predictor-mcp": {
      "url": "https://api.gasfeepredictor.com/api/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure). The type must be streamableHttp for a remote HTTP server.

Cline configuration

{
  "mcpServers": {
    "gas-fee-predictor-mcp": {
      "type": "streamableHttp",
      "url": "https://api.gasfeepredictor.com/api/mcp",
      "disabled": false
    }
  }
}

VS Code

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

VS Code configuration

{
  "servers": {
    "gas-fee-predictor-mcp": {
      "type": "http",
      "url": "https://api.gasfeepredictor.com/api/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 gas-fee-predictor-mcp https://api.gasfeepredictor.com/api/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": {
    "gas-fee-predictor-mcp": {
      "url": "https://api.gasfeepredictor.com/api/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": {
    "gas-fee-predictor-mcp": {
      "serverUrl": "https://api.gasfeepredictor.com/api/mcp"
    }
  }
}
