Show HN: Warden MCP, an MCP server for agents to quote and trade onchain

Warden Protocol released Warden MCP, a Model Context Protocol server at tokens.wardenprotocol.org/mcp that lets AI apps including Claude, ChatGPT, Grok, Claude Code, Codex, Hermes and OpenClaw quote and execute onchain token trades across Base, BNB Chain, Robinhood Chain and Arc. The server requires no key in Claude, ChatGPT, Dots or Grok, while Claude Code, Codex, Hermes and OpenClaw use a key prefixed wk_ stored in a setting named WARDEN_TOKEN. Trades stay inside Warden's custody and are checked twice before signing, with a daily budget, a per-trade cap during hands-free sessions and the ability to stop a session or revoke all keys at any time.
