Flashift MCP server

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.

• Remote endpoint: https://mcp.flashift.app/mcp (Streamable HTTP)
• API key: none required
• Custody: none. Flashift never asks for or stores private keys or seed phrases. See SECURITY.md.
• Documentation: Flashift MCP Service · How Flashift works

Quick start

Remote (recommended)

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

Tools

Tool	What it does
get_currencies	Lists supported currencies and networks. Filter by symbol, network, or search, and cap results with limit (default 50).
get_estimated_amount	Quotes a swap across all providers: estimated output, min/max limits, rate type, and AI tags.
create_transaction	Creates a swap with a chosen provider and returns a deposit address.
get_transaction_info	Returns real-time status for an existing swap.
get_providers	Lists the exchange providers Flashift aggregates and whether each is available.

get_currencies

Parameter	Type	Required	Description
symbol	string	no	Currency symbol, e.g. btc, eth, usdt
network	string	no	Network, e.g. eth, bsc, trx, btc
search	string	no	Matches symbol, full name, or network
limit	integer	no	Maximum items returned (default 50)

get_estimated_amount

Parameter	Type	Required	Description
symbol_from	string	yes	Source currency, e.g. btc
network_from	string	yes	Source network, e.g. btc
symbol_to	string	yes	Target currency, e.g. usdt
network_to	string	yes	Target network, e.g. trc20
amount	number	yes	Amount of source currency (> 0)
type	"float" | "fixed"	no	Rate type. Both are evaluated if omitted
exchange_list	string	no	Comma-separated preferred providers, e.g. changenow

Each quote can carry one or more AI tags:

Tag	Meaning
AI Best Rate	Best rate weighted by user feedback and provider reliability
Recommended	Best overall balance of rate, KYC level, and speed
Best Rate	Highest raw rate right now
Best in KYC	Lowest KYC requirement among the quoted providers

create_transaction

Parameter	Type	Required	Description
provider_name	string	yes	Provider from the quote, e.g. changenow
symbol_from	string	yes	Source currency
network_from	string	yes	Source network
symbol_to	string	yes	Target currency
network_to	string	yes	Target network
amount	number	yes	Amount of source currency (> 0)
fixed	boolean	yes	true for a fixed rate, false for floating
to_address	string	yes	Wallet address that receives the swapped funds
to_extra_id	string	no	Memo or destination tag, when the target network needs one (XRP, TON, XLM, ...)
user_id	string	no	Affiliate or user ID for tracking

Returns an exchange ID and a deposit address. The user sends funds to that address from their own wallet; the provider then pays out to to_address.

get_transaction_info

Parameter	Type	Required	Description
exchange_id	string	yes	ID returned by create_transaction

get_providers

No parameters.

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.
