  "account": "Local developers can enhance AI assistants like MCP agents by integrating DevUtils MCP Server, which offers a local set of 36 developer utilities through the Model Context Protocol (MCP). This server provides functionality for hashing, encoding, ID generation, JWT inspection, JSON formatting, network calculations, and text utilities, all running locally without external dependencies.\n\nTo get started, install the stable v1.1.0 release using npx -y devutils-mcp-server@1.1.0. Connect it to your MCP client by adding a command configuration in your client's configuration file, specifying the command as npx and the arguments as devutils-mcp-server@1.1.0. Once connected, you can utilize tools like hash_sha256, json_validate, generate_uuid, cidr_calculate, and text_stats.\n\nThe server operates using stdio, waiting for JSON-RPC messages on standard input and writing protocol responses to standard output. This means you'll need to send JSON-RPC messages to the server using standard input and read the protocol responses from standard output. This setup allows the assistant to call the tools during multi-step conversations without the need to invent an implementation.\n\nHowever, it's important to note that DevUtils is not a security oracle. While tools like jwt_decode and jwt_validate can decode JWT tokens, they do not verify the cryptographic signature, and the server does not guarantee the token's authenticity or trustworthiness. Use these tools for bounded operations, providing explicit tools and typed arguments, and always inspect the results to ensure they meet your needs.",
  "summary": "AI assistants are useful at translating intent into actions, but small developer utilities are an easy place for an agent to guess. A guessed hash, a malformed JSON transformation, or a misunderstood JWT timestamp can waste more time than the original task. DevUtils MCP Server provides a local set of 36 developer utilities through the Model Context Protocol (MCP). The server exposes hashing,…",
