Blockchain MCP

The Blockchain MCP powered by Tatum bridges the gap between large language models and the vast ecosystem of blockchain networks. By exposing Tatum’s comprehensive Blockchain Data API and RPC Gateway through the Model Context Protocol, it gives AI assistants instant, programmatic access to over 130 distinct networks, from Bitcoin and Ethereum to Solana, Avalanche, and dozens of EVM‑compatible chains. This eliminates the need for developers to write custom connectors or maintain multiple SDKs, enabling a single, unified interface that can read and modify on‑chain data.

At its core, the server offers two complementary tool families. The Blockchain Data tools provide high‑level queries such as wallet balances, transaction histories, NFT metadata, and real‑time exchange rates. These functions are designed for quick, declarative data retrieval that an LLM can interpret and present in natural language. The RPC Gateway tools, on the other hand, allow raw RPC calls to any supported chain. This gives developers the flexibility to perform low‑level operations—like submitting raw transactions or querying smart contract state—that go beyond the predefined data endpoints.

Developers benefit from this setup in several practical scenarios. For a decentralized finance (DeFi) assistant, the server can fetch portfolio snapshots or token balances and immediately suggest yield‑optimizing actions. A non‑fungible asset manager can pull up the latest metadata and ownership history for a collection, while a compliance bot can flag malicious addresses using the provided checks. Because the server supports both EVM and non‑EVM chains, a single AI workflow can span Bitcoin, Solana, Cardano, and more without changing context or switching providers.

Integration into an AI workflow is straightforward: the MCP client declares the server in its configuration, supplies a Tatum API key, and then calls any of the exposed tools. The server handles authentication, rate‑limiting, and network routing transparently, returning JSON payloads that the model can consume. This tight coupling lets developers build conversational agents that can answer “What is my ETH balance?” or “Show me the latest block on Solana” with real‑time data, all while keeping the user experience seamless.

What sets this MCP apart is its breadth of network coverage and dual‑layer toolset. By combining high‑level data retrieval with low‑level RPC execution, it offers both ease of use and deep control. For teams building blockchain‑aware AI assistants—whether for portfolio management, compliance monitoring, or developer support—the Blockchain MCP provides a single, reliable gateway to the entire multichain landscape.
