Moralis Web3 API MCP Server

Overview

The Moralis Web3 API MCP server is a bridge that exposes the full breadth of Moralis’ blockchain data services to AI assistants through the Model Context Protocol. By wrapping each Moralis endpoint as an MCP tool, it gives Claude (or any MCP‑compatible client) instant, typed access to over a hundred blockchain APIs without the need for custom integrations or SDKs. Developers can query block data, NFT collections, token statistics, wallet analytics, and DeFi positions all from a single, well‑structured interface.

This server solves the common pain of fragmented blockchain APIs. Traditionally, a developer must handle multiple providers—each with its own authentication scheme, rate limits, and response formats. The Moralis MCP server consolidates these disparate endpoints into a unified schema that follows MCP’s standard request/response contracts. This means AI assistants can ask for “the latest block on Polygon” or “NFT floor price for a specific collection,” and the server translates those queries into the appropriate Moralis calls, normalizes the data, and returns it in a predictable format.

Key capabilities include:

• Multi‑chain coverage: Ethereum, Polygon, BSC, Avalanche, and more are all reachable through the same tool set.
• Comprehensive data: From raw block contents to wallet profitability, every Moralis endpoint is exposed—NFT metadata, token transfers, DeFi positions, and even spam contract reviews.
• Dynamic endpoint loading: The server reads an registry, so adding or removing functionality only requires updating that file, not touching the MCP core.
• Standardized communication: All tools adhere to MCP’s JSON schema, making them discoverable and type‑checked by AI assistants.

Real‑world scenarios that benefit from this server include:

• DeFi analytics bots: A Claude agent can pull real‑time liquidity reserves, trending tokens, and wallet positions to generate market insights.
• NFT marketplace assistants: By querying floor prices, collection stats, and trait rarity, an AI can advise collectors on investment opportunities.
• Wallet monitoring services: Automated agents can fetch wallet chains, profitability metrics, and ENS resolution to provide personalized portfolio dashboards.
• Compliance tooling: The “review contracts for spam” utility allows auditors to flag potentially malicious addresses before they interact with users.

Integrating the Moralis MCP server into an AI workflow is straightforward: add it as a server in the Claude configuration, and the assistant automatically discovers all available tools. From there, natural language prompts can trigger complex blockchain queries without any custom code, enabling rapid prototyping and deployment of blockchain‑aware AI applications.
