CosmWasm MCP Server Template

The CosmWasm MCP Server Template is a Rust‑based framework that turns any CosmWasm smart contract into an AI‑ready service. By exposing a contract’s query and execute entry points through the Model Context Protocol (MCP), the server allows AI assistants—such as Claude—to interact with blockchain logic in a structured, type‑safe manner. This removes the need for bespoke integration code and gives developers a plug‑and‑play gateway between conversational agents and on‑chain functionality.

At its core, the server wraps a contract’s and types into JSON schemas that MCP clients can consume. When a user asks an AI to perform an on‑chain action, the assistant sends a well‑formed request to the MCP server. The server then constructs the appropriate CosmWasm or , signs it with a configured wallet, and broadcasts the transaction. The response is streamed back to the client as JSON, enabling real‑time feedback in conversational flows.

Key capabilities include:

• Universal contract support: The template is agnostic to the specific contract; developers simply replace a single dependency line and ensure their contract exposes the required message types.
• Library‑friendly design: Contracts can be built as libraries, preventing entry points from leaking into the binary and keeping the MCP server lightweight.
• Environment‑aware addresses: The template contains placeholders for mainnet and testnet contract addresses, allowing seamless switching between networks.
• Type safety: By generating JSON schemas from Rust types, the server guarantees that only valid messages reach the blockchain, reducing runtime errors.

Typical use cases span from decentralized finance (DeFi) dashboards that let users trade tokens through a chat interface, to governance tools where AI can draft proposals and submit votes. In research settings, the server enables rapid prototyping of on‑chain experiments without writing custom RPC wrappers. For developers building AI‑powered dApps, the MCP server eliminates boilerplate, accelerates integration, and ensures that all interactions are auditable and signed by a trusted wallet.

Overall, the CosmWasm MCP Server Template streamlines the bridge between conversational AI and blockchain logic. It offers a reusable, secure, and developer‑friendly foundation that can be adapted to any CosmWasm contract with minimal changes, making it an invaluable asset for teams looking to embed on‑chain capabilities into AI workflows.
