Set up ari-mcp-server in Claude Desktop

communityunknownneeds caution

MCP server that stops AI agents from overpaying. Drops into Claude Desktop, Cursor, Continue, Windsurf, Zed, ChatGPT desktop, and Gemini CLI to give any agent live fair-market-value lookups, a green/amber/red prepay verdict, and cryptographically-signed (Ed25519) receipts for every x402 / MPP / agentic-payment quote.

01Configuration

{
  "mcpServers": {
    "ari-mcp-server": {
      "command": "uvx",
      "args": [
        "ari-mcp-server"
      ]
    }
  }
}

Add this to claude_desktop_config.json. Generated from the captured install method (uvx); the mcpServers shape is shared across Claude Desktop, Cursor, Windsurf, Cline, and VS Code.

02Steps

Make sure Claude Desktop is installed and up to date.
Open claude_desktop_config.json and add the block above (merge into any existing mcpServers).
Provide any required API keys/credentials as environment variables.
Restart Claude Desktop and confirm ari-mcp-server’s tools appear.
