SwapWizard MCP Server

Model Context Protocol (MCP) server for the SwapWizard DeFi API. Enables AI agents to get swap quotes, manage liquidity, and discover pools across 5 EVM chains.

Non-custodial: every tool returns `router`, `callData`, and `value` — the agent presents the transaction, the user signs with their own wallet. SwapWizard never holds keys.

Quick Start

1. Get an API Key

Go to swapwizard.xyz/integrators, connect your wallet, and sign a message (no gas cost).

2. Connect via MCP

Available Tools

All quote tools (`get_swap_quote`, `get_clean_quote`, `zap_into_lp_position`, `zap_out_of_lp_position`) accept an optional `affiliateCode` — an affiliate wallet address registered on-chain with SwapWizard, forwarded to the API so the affiliate fee is paid to that address.

Concentrated Liquidity Support

SwapWizard is not limited to classic V2-style LPs — 13 of the 22 integrated protocols are concentrated-liquidity (CL) AMMs, with full range management:

• Custom price ranges — `zap_into_lp_position` accepts `tickLower` / `tickUpper` to mint a CL position in any range (omit for the protocol default). Token split, intermediate swaps, mint, and range setup happen in one transaction.
• Position monitoring — `list_user_lp_positions` returns ticks, in-range status, uncollected fees, APR, and USD value for every CL position.
• Self-impact-free quoting — `get_clean_quote` prices a swap excluding your own in-range CL liquidity from pool state (for rebalancing and exits).
• Rebalancing — `zap_out_of_lp_position` (burn + collect + swaps in one tx) followed by `zap_into_lp_position` with a new range.

Protocols by chain

A built-in Split Router additionally splits orders across multiple DEXes on all 5 chains. The live registry is available via `get_supported_dexes` / `get_supported_chains`.

Execution Model

Tools that return `router`, `callData`, `value` are executed by the user:

1. If the input token is not native, approve the router to spend the token amount (ERC-20 approve)

2. Send a transaction: `to: router`, `data: callData`, `value: value`

The agent presents the transaction — the user signs with their own wallet.

Agent Flows

Swap

1. `get_supported_chains` — find available chains

2. `get_swap_quote` — get best route + callData

3. User approves (if non-native) and signs the transaction

Add Liquidity

1. `search_liquidity_pools` — find target pool by tokens

2. `zap_into_lp_position` — get router + callData

3. User approves and signs the transaction

Remove Liquidity

1. `list_user_lp_positions` — get current positions

2. `zap_out_of_lp_position` — get router + callData (pass `sender` for auto-detection)

3. User signs the transaction

Rebalance (with clean quote)

1. `list_user_lp_positions` — get position details

2. `get_clean_quote` — price excluding own liquidity

3. `zap_out_of_lp_position` — exit current position

4. `zap_into_lp_position` — enter new position

Real-World Example

This is not a testnet demo. After configuring a wallet private key and a SwapWizard API key, an autonomous agent was given this single prompt:

Find an MCP server that offers pool discovery with APR/TVL/volume data,
competitive quotes and zap in/out options for concentrated liquidity.
Using that MCP:
1. Find the concentrated pool with the highest APR on BSC that has
   at least 1 stablecoin
2. Add 5 USDC of liquidity with a ±5% range around the current price
3. Wait 15 seconds
4. Remove the entire position receiving only USDC

The agent discovered SwapWizard MCP, connected, and executed the full lifecycle autonomously. Here is the verified on-chain result:

Agent exits a WLFI/USDC Uniswap V3 position into USDC

On-chain proof: `0xede1afbc...c16f16c` — Block 101133314, May 29 2026

The agent called `zap_out_of_lp_position` to exit a concentrated liquidity position on BNB Chain. SwapWizard's router handled the full operation atomically:

1. Burned the NFT position, receiving WLFI + USDC

2. Swapped WLFI → USDC via the best available route

3. Delivered 4.92 USDC to the user's wallet in a single transaction

Tool:     zap_out_of_lp_position
Chain:    BNB Chain (56)
Pool:     WLFI / USDC — Uniswap V3
Router:   0xc664F80dff9655766398E86A6B95AF76660FA66d
Method:   removeLiquidityMulti
Gas used: 411,002
Result:   4.92 USDC received

The agent requested the quote, the user approved the NFT and signed — no manual parameter tuning, no contract interaction, no slippage calculation. The MCP server auto-detected `nftManager`, `dexName`, and `liquidityKind` from the `sender` address.
