Moralis MCP Server

A TypeScript-based MCP server that implements a wrapper to the Moralis rest API.

![smithery badge](https://smithery.ai/badge/@MoralisWeb3/moralis-mcp-server) ## 🧠 Overview The **Moralis MCP Server** is a local or cloud-deployable engine that connects natural language prompts to real blockchain insights — allowing AI models to query wallet activity, token metrics, dapp usage, and more without custom code or SQL. Built on top of the [Model Context Protocol](https://github.com/modelcontextprotocol/spec), this server makes it easy for LLMs to talk to Moralis APIs in a consistent, explainable, and extensible way. - 🔗 Fully pluggable: swap LLMs, customize retrieval logic, or extend with your own tools - 🧱 Works with OpenAI, Claude, and open-source models - 🧠 Powers agents, devtools, bots, dashboards, and beyond ## ⚙️ Common Use Cases - 🤖 AI agents & assistants: “What’s this wallet’s trading history?” - 📈 Devtools: on-chain QA, testing, CLI integrations - 📊 Dashboards: natural language to charts/data - 📉 Monitoring: alerting & summarization for tokens/dapps - 🧠 Trading bots: LLM-driven strategies with real blockchain grounding ## 🔐 Getting an API Key To use this MCP server with Moralis APIs, you'll need an API key: 1. Go to [Moralis](https://admin.moralis.com) developer portal 2. Sign up and log in 3. Navigate to your [API Keys page](https://admin.moralis.com/api-keys) from the main menu 4. Copy your key and configure it in your config file (see next section), or set it in your environment: ```bash export MORALIS_API_KEY= ``` > ⚠️ Note: Some features and endpoints require a Moralis paid plan. For full access and production-grade performance, we recommend signing up for a paid tier. ## 🚀 Usage with a Client To connect the MCP server to a compatible client (e.g. Claude Desktop, OpenAI-compatible agents, VS Code extensions, etc.), configure the client to launch the server as a subprocess. Most clients support a simple config file - for example, you might create a file like mcp.json in the client’s configuration directory with the following: ```json { "mcpServers": { "serverName": { "command": "npx @moralisweb3/api-mcp-server", "args": [], "env": { "MORALIS_API_KEY": "" } } } } ``` This setup can be adapted for any client that supports MCP servers. Replace the example values with those specific to your use case. ### Installing via Smithery To install Moralis API Server for Claude Desktop automatically via [Smithery](https://smithery.ai/server/@MoralisWeb3/moralis-mcp-server): ```bash npx -y @smithery/cli install @MoralisWeb3/moralis-mcp-server --client claude ``` ## 🖥️ Using as a Server The server accepts an optional `--transport` argument to specify the transport type. The available transport types are: - `stdio`: Communicates over standard input/output (default). - `web`: Starts a HTTP server for communication. - `streamable-http`: Starts an HTTP server with streamable endpoints. ### Examples 1. **Using the default `stdio` transport**: ```bash moralis-api-mcp --transport stdio ``` 2. **Using the `web` transport**: ```bash moralis-api-mcp --transport web ``` This will start a HTTP server. You can send requests to the server using tools like `curl` or Postman. 3. **Using the `streamable-http` transport**: ```bash moralis-api-mcp --transport streamable-http ``` This will start an HTTP server. You can send requests to the server using tools like `curl` or Postman. ### Notes - Ensure that the required environment variables (e.g., `MORALIS_API_KEY`) are set before starting the server. - For custom configurations, you can pass additional arguments or environment variables as needed. - Refer to the documentation for more details on each transport type. ## 🛠 Development Install dependencies: ```bash npm install ``` Build the server: ```bash npm run build ``` For development with auto-rebuild: ```bash npm run watch ``` ### 🐞 Debugging Since MCP servers communicate over stdio, debugging can be challenging. We recommend using the [MCP Inspector](https://github.com/modelcontextprotocol/inspector), which is available as a package script: ```bash npm run inspector ``` The Inspector will provide a URL to access debugging tools in your browser. ## 💬 Example Prompts Here are some example prompts you can use with your AI agent through the MCP server: ``` - What’s the current price of PEPE and Ethereum? - What is the current trading sentiment for TOSHI on Base — bullish or bearish? - Show me the NFTs owned by `vitalik.eth` on Base. - What tokens does wallet `0xab71...4321` hold? - When was wallet 0xabc...123 first and last seen active on Ethereum, Base, and Polygon? - Show me the complete transaction history for 0xabc...123 across Ethereum, Base, and BNB Chain. - What is the current net worth in USD of wallet 0xabc...123? - Find wallet addresses that are likely associated with Coinbase. - Analyze the current holder distribution of SPX6900 — include whales, small holders, and recent growth trends. - Show me PEPE’s daily OHLC data for the past 30 days and provide a summary of the trend — is it bullish or bearish? ``` These prompts are parsed and mapped to structured Moralis API calls using the MCP method registry. > 💡 You can also build custom prompts based on any supported method. ## 📚 API Reference The Moralis MCP Server wraps and translates prompts into Moralis REST API calls. You can explore the underlying API surface here: 🔗 **[Moralis Swagger Docs (v2.2)](https://deep-index.moralis.io/api-docs-2.2/)** This documentation covers endpoints for: - Token pricing - Wallet activity - NFT metadata and ownership - Transfers and transactions - And more
