Overview

Maestro MCP Server facilitates direct interaction with the Bitcoin network by bridging AI models with the Maestro API. It provides structured tooling to query blockchain data, including blocks, transactions, wallet information, and mempool status, supporting both Bitcoin Mainnet and Testnet4 environments. Built using the Bun runtime, the server utilizes a streamable HTTP transport mechanism. Users are required to provide a Maestro API key to authenticate requests, enabling LLMs to execute complex queries and monitor on-chain activity effectively.

Our verdict

With a security score of 38/100, this server is classified as high risk. The evaluation reflects that the project is community-maintained rather than official vendor-supported and lacks an independent editorial security review. Potential users should be aware that critical authentication and read-only access mechanisms have not yet been formally audited. It is recommended primarily for experimental or non-production environments where API access control can be closely monitored.

  • Supports both Bitcoin Mainnet and Testnet4 networks
  • Contains only 9 direct dependencies
  • Licensed under the Apache-2.0 license
  • Community-maintained with no official vendor backing
  • Authentication and read-only implementations lack review
  • High security risk score due to limited external oversight

Setup
