Omnicall

What is Omnicall?

Omnicall is an MCP server that provides agents with access to 248 LLMs (GPT, Claude, Gemini, Grok, DeepSeek, Llama, Qwen, Mistral) plus image, video, voice, and music generation, live crypto / DEX / DeFi / prediction-market data, web search, multi-platform research, X profiles, and on-chain reads — all through a single keyless endpoint. It is designed for developers using Claude Code, Cursor, Cline, Claude Desktop, or any MCP client.

How to use Omnicall?

Install Omnicall with a single command: for Claude Code, run claude mcp add omnicall npx -y omnicall-mcp. For Cursor, Cline, Claude Desktop, or Windsurf, add the corresponding JSON entry to your MCP config. Once installed, call the free list_endpoints tool to see all available tools. No API key or subscription is required; you pay per call in USDC on Base or Solana via x402, or pass a funded gck_ credit key.
