The MCP Bundle format (MCPB) is now part of the Model Context Protocol project. This distribution format simplifies how developers package and share local MCP servers, enabling users to install them across any compatible client, including the Claude desktop app, Claude Code, and MCP for Windows. What are MCP Bundles? MCP Bundles are ZIP archives containing a local MCP server and a manifest.json that describes the server and its capabilities. The format is similar to Chrome extensions (.crx) or VS Code extensions (.vsix), enabling end users to install local MCP servers with a single click. ...

Many of us are still exploring the nooks and crannies of MCP and learning how to best use the building blocks of the protocol to enhance agents and applications. Some features, like Prompts, are frequently implemented and used within the MCP ecosystem. Others may appear a bit more obscure but have a lot of influence on how well an agent can interact with an MCP server. Server instructions fall in the latter category. ...

Update (November 11, 2025): The specification release candidate (RC) date has been shifted from November 11th to November 14th, 2025. The specification release date remains to be November 25th, 2025. Release Timeline The next version of the Model Context Protocol specification will be released on November 25th, 2025, with a release candidate (RC) available on November 11th, 2025. We’re building in a 14-day RC validation window so client implementors and SDK maintainers can thoroughly test the protocol changes. This approach gives us the focused time we need to deliver critical improvements while applying our new governance model to the process. ...

MCP (Model Context Protocol) prompts enable workflow automation by combining AI capabilities with structured data access. This post demonstrates how to build automations using MCP’s prompts and resource templates through a practical example. This guide demonstrates how MCP prompts can automate repetitive workflows. Whether you’re interested in the MCP ecosystem or simply want to leverage AI for workflow automation, you’ll learn how to build practical automations through a concrete meal planning example. No prior MCP experience needed—we’ll cover the fundamentals before diving into implementation. ...
