Flashift MCP Server

Zero-key, non-custodial cross-chain crypto swap aggregator for AI agents. Flashift routes swaps across 100+ blockchains and 15+ liquidity providers, with AI-ranked routing tags such as AI Best Rate and Best in KYC.

Quick start

Add Flashift to any MCP client that supports remote Streamable HTTP servers (Claude, Cursor, Windsurf, VS Code, and others):

{
  "mcpServers": {
    "flashift": {
      "url": "https://mcp.flashift.app/mcp"
    }
  }
}
Local (stdio bridge)

For clients that only support stdio servers, connect through mcp-remote:

{
  "mcpServers": {
    "flashift": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://mcp.flashift.app/mcp"]
    }
  }
}

Requires Node.js 18 or newer.

Claude Code
claude mcp add --transport http flashift https://mcp.flashift.app/mcp

Typical flow

  1. get_currencies to confirm the symbol and network pair.
  2. get_estimated_amount to compare providers and pick one, usually by AI tag.
  3. create_transaction with the chosen provider_name and the user's receiving address.
  4. The user sends the deposit from their own wallet.
  5. get_transaction_info to track the swap until it completes.

Security

Flashift is non-custodial. It only generates deposit routes and never requests, receives, or stores private keys or seed phrases. See SECURITY.md for the full model and how to report a vulnerability.
