MCP clients (Claude Code, Cursor, others) with FlexYield

Connect the gateway as an MCP server — every capability as a tool, no code.

Install

claude mcp add --transport sse flexyield https://flexyield.io/mcp/sse --header "Authorization: Bearer fy_your_api_key"

Connect and call

{
  "mcpServers": {
    "flexyield": {
      "url": "https://flexyield.io/mcp/sse",
      "headers": { "Authorization": "Bearer fy_your_api_key" }
    }
  }
}

Replace fy_your_api_key with a key from your dashboard (free tier at registration). Chain slugs: eth_mainnet base_mainnet arbitrum_one optimism_mainnet polygon_pos solana_mainnet — each has its own measured page.

Notes

• An agent can claim its own key by wallet identity — see /skill.md. Discovery files: /.well-known/mcp/server-card.json, /.well-known/agent-skills/index.json.
