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

get_currencies to confirm the symbol and network pair.
get_estimated_amount to compare providers and pick one, usually by AI tag.
create_transaction with the chosen provider_name and the user's receiving address.
The user sends the deposit from their own wallet.
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.
