The official PHP SDK for the Model Context Protocol is now generally available. Built in collaboration with the PHP Foundation and Symfony, the PHP SDK handles protocol details, so developers don’t have to worry about low-level mechanics and can focus on building their applications. The initial release enables PHP developers to build MCP servers, exposing tools, prompts, and resources to AI applications. Support for PHP applications to act as MCP clients will follow. The PHP SDK now joins 9 other officially supported language SDKs in the MCP ecosystem, making it easier for developers everywhere to adopt MCP in their preferred language. ...

The Model Context Protocol (MCP) has adopted OAuth 2.1 as the foundation for its authorization framework. A key part of the authorization flow that MCP is particularly reliant on is client registration. This is especially important in a world where clients and servers don’t have a pre-existing relationship - we can’t assume that we will always know which MCP clients will connect to which MCP servers. This design highlights two challenges that need to be addressed: ...

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. ...

Since its open source release in November of 2024, the Model Context Protocol project has grown faster than we could have ever imagined. That’s a wonderful problem to have, but with growth come growing pains. Our existing processes, which worked well for a small team, have started to show their limits. Today, we’re taking a big step to ensure MCP can continue to grow and thrive. We’re introducing a formal governance model designed to bring clarity to the development process while preserving the collaborative, open source spirit that has made MCP successful. ...
