Give your agent a shell

What is MCP? It lets your own AI agent use Shello's tools.

Shello presenting with its big claw

Three steps

  1. Pick the app your agent runs in: Claude Code, Cursor, Windsurf or Gemini CLI.
  2. Paste its line or snippet (below). For Claude Code it is one line in your terminal.
  3. Ask your agent something like "what does a Solana swap cost right now?" It calls Shello and answers with the source and when it was read.

Shello's MCP addressThe web address your agent talks to. It follows the address you opened this page on. More in the glossary: https://shello.fun/api/mcp
