1inch MCP

What 1inch MCP MCP server does

The 1inch MCP MCP server gives compatible AI clients access to selected 1inch capabilities through a remote MCP endpoint at https://api.1inch.com/mcp/protocol. It is intended for assistants that need to search 1inch documentation, retrieve SDK examples, access market and wallet data, or work with supported trading and infrastructure APIs.

Available areas include token swaps, including Classic, Fusion, and cross-chain workflows; limit orders; portfolio and wallet information; token balances, transaction history, NFTs, token data, spot prices, gas prices, and charts. The server also covers Web3 RPC, transaction gateway and domain features through authenticated product API calls. WalletConnect pairing and Aqua strategy analytics are available as separate capabilities, while organization-scoped request log lookup is optional.

How it works

The service is hosted by 1inch and configured as an HTTP MCP server rather than installed as a local process. An MCP-compatible client sends tool requests to the published endpoint. The repository also provides Agent Skills that describe the endpoint, authentication patterns, client setup, and product-specific call recipes. Skills are loaded on demand and can guide an agent toward the relevant domain workflow.

Public tools include search, list_examples, and get_example. Read-only Aqua access is also public when that capability is enabled. The swap, orderbook, product_api, and optional debug tools require authentication. Authentication can use an API key from the 1inch Business Portal or OAuth, depending on the client and setup.

Setup and configuration

For Cursor, install 1inch MCP from the Cursor Marketplace, or add the hosted URL to .cursor/mcp.json. Cursor also supports entering an API key through the plugin's setup values; leaving that field empty uses public tools and OAuth. Claude Code can add the server with its HTTP transport command, and VS Code Copilot can configure it in .vscode/mcp.json with `
