MCP Server

Ask your AI assistant to bridge 1 ETH from Arbitrum to Solana. Get a quote in seconds. Click one link to execute. The deBridge MCP Server (@debridge-finance/debridge-mcp) gives AI agents direct access to the deBridge Liquidity Network — search 40,000+ tokens, get quotes for cross-chain and same-chain swaps, generate transaction data, and create shareable deBridge App links based on custom linking. No API keys required.

How It Works

The MCP server is a stateless proxy that translates MCP tool calls into deBridge REST API requests. It does no heavy computation, keeps no state, and stores nothing. The AI agent never talks to the deBridge API directly — all requests flow through the server. The server calls public deBridge APIs, which provide a generous 50 requests per minute rate limit without authentication.

Use Cases

Developers building on deBridge — test quotes, check token addresses, and verify chain IDs without leaving the IDE. The MCP server turns an AI assistant into a live deBridge API explorer.
Power users in AI chat — get quick swap quotes as part of a broader conversation. One click on the generated link to execute the swap.
Analysts and content creators — query live pricing data conversationally. Compare bridge rates across chains for reports and research.
Trading bots and dashboards — autonomous agents that monitor prices across chains and generate swap links when conditions are met.
Integrate with the existing AI agents — any agent that supports MCP servers can use this to offer deBridge swaps without building their own API integration and expand their capabilities into DeFi space.

Quick Start

Add this to your MCP configuration file:

{
  "mcpServers": {
    "debridge-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "@debridge-finance/debridge-mcp@latest"
      ]
    }
  }
}

This works for most AI coding agents (Cursor, Claude Code, Windsurf, Cline, etc.). See Configuration for framework-specific paths and options.

Claude Desktop requires HTTP transport. Start the server with MCP_TRANSPORT=http npx -y @debridge-finance/debridge-mcp@latest, then configure the URL http://localhost:3000/mcp. See Configuration for details.

Tools

`get_instructions`

Returns the built-in workflow guide that describes the recommended sequence for using the deBridge MCP tools. No parameters.

Call this first to understand the recommended workflow before using other tools.

`search_tokens`

Resolves token names, symbols, or addresses to contract addresses across supported chains.

Parameter	Type	Required	Description
`query`	string	Yes	Token name, symbol, or address
`chainId`	string	No	Filter by chain ID
`name`	string	No	Filter by token name (partial match)
`limit`	number	No	Max results (default: 10)

Results are ranked by relevance: exact symbol match → exact name match → starts-with → substring. Example:

{
  "query": "USDC",
  "chainId": "1"
}

{
  "tokens": [
    {
      "symbol": "USDC",
      "name": "USD Coin",
      "address": "0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48",
      "decimals": 6,
      "chainId": "1"
    }
  ]
}

`get_supported_chains`

Lists all blockchain networks supported by DLN. No parameters. Example response:

{
  "chains": [
    { "chainId": "1", "chainName": "Ethereum" },
    { "chainId": "56", "chainName": "BNB Chain" },
    { "chainId": "137", "chainName": "Polygon" },
    { "chainId": "42161", "chainName": "Arbitrum" },
    { "chainId": "7565164", "chainName": "Solana" }
  ]
}

`create_tx`

Get quotes for cross-chain swaps.

Parameter	Type	Required	Description
`srcChainId`	string	Yes	Source chain ID
`srcChainTokenIn`	string	Yes	Source token address
`srcChainTokenInAmount`	string	Yes	Amount in smallest units (wei/lamports)
`dstChainId`	string	Yes	Destination chain ID
`dstChainTokenOut`	string	Yes	Destination token address
`dstChainTokenOutRecipient`	string	Yes	Recipient wallet address
`srcChainOrderAuthorityAddress`	string	Yes	Sender’s wallet address
`dstChainOrderAuthorityAddress`	string	Yes	Recipient’s authority address
`dstChainTokenOutAmount`	string	No	Output amount or `"auto"` (default)
`prependOperatingExpenses`	boolean	No	Include operating expenses in input

All token amounts must be in the smallest unit of the token. For example, 1 USDC = "1000000" (6 decimals), 1 ETH = "1000000000000000000" (18 decimals). Use search_tokens to find the correct decimals value.

The native token (ETH, BNB, MATIC, etc.) is represented by the zero address: 0x0000000000000000000000000000000000000000.SOL on Solana is represented with 11111111111111111111111111111111 and Wrapped SOL (WSOL) is represented with So11111111111111111111111111111111111111112.

`estimate_same_chain_swap`

Estimates a same-chain token swap. Returns the expected output amount, fees, slippage, and aggregator comparisons.

Parameter	Type	Required	Description
`chainId`	string	Yes	Chain ID (native or deBridge internal)
`tokenIn`	string	Yes	Input token address (zero address for native)
`tokenInAmount`	string	Yes	Amount in smallest units (wei/lamports)
`tokenOut`	string	Yes	Output token address
`tokenOutAmount`	string	No	Expected output or `"auto"` (default)
`slippage`	string	No	Slippage tolerance or `"auto"` (default)
`affiliateFeePercent`	number	No	Affiliate fee percentage
`affiliateFeeRecipient`	string	No	Affiliate fee recipient address

This tool accepts both native chain IDs (e.g. 4326 for MegaETH) and deBridge internal IDs.

`get_trade_dapp_url`

Generates a shareable deBridge App URL for a given trade.

Parameter	Type	Required	Description
`inputChain`	string	Yes	Source chain ID
`outputChain`	string	Yes	Destination chain ID
`amount`	string	Yes	Human-readable amount (e.g., `"1.5"`)
`inputCurrency`	string	No	Source token address (empty for native)
`outputCurrency`	string	No	Destination token address (empty for native)
`dlnMode`	string	No	`"simple"` or `"advanced"` (default: `"simple"`)

Unlike create_tx, this tool uses human-readable amounts — pass "1.5" for 1.5 ETH, not the wei value.

Example output:

https://app.debridge.finance/order?inputChain=1&outputChain=42161&inputCurrency=&outputCurrency=&amount=1.5&dlnMode=simple

Workflow

The recommended sequence for performing a swap:

Resolve chains — call get_supported_chains to find the chain IDs for the source and destination networks.
Resolve tokens — call search_tokens with the chain ID to get the token contract addresses and decimals.
Get a quote — call create_tx for cross-chain swaps or estimate_same_chain_swap for same-chain swaps.
Share a link — call get_trade_dapp_url to generate a deBridge App URL the user can open to execute the swap.

The MCP server never touches private keys or signs transactions. The user always completes the swap themselves: open the generated link, connect their wallet, review, and sign. This browser handoff is a deliberate security boundary — the server handles pricing and quoting, while the user retains full control over execution.

Example

Prompt: Bridge 1 ETH from Arbitrum to USDC on Solana

Resolve chains — call get_supported_chains to find that Arbitrum is 42161 and Solana is 7565164.
Resolve source token — call search_tokens with query: "ETH" and chainId: "42161" to get the native token address (0x0000000000000000000000000000000000000000, 18 decimals).
Resolve destination token — call search_tokens with query: "USDC" and chainId: "7565164" to get the USDC address on Solana.
Create the transaction — call create_tx with the resolved addresses and srcChainTokenInAmount: "1000000000000000000" (1 ETH in wei). The response includes the estimated output amount and transaction data.
Generate a link — call get_trade_dapp_url with inputChain: "42161", outputChain: "7565164", amount: "1", and the resolved token addresses.
User completes the swap — the user opens the generated link in their browser, connects their wallet, and signs the transaction.
