MODEL CONTEXT PROTOCOL

Vercel, OpenAI, GitHub, Microsoft, AWS, and Cursor collaborated on Agent Plugins 1.0.0, an open standard that packages Agent Skills and MCP servers into one portable plugin. ChatGPT, Codex, Cursor, GitHub Copilot, Kiro, and VS Code load the format on day one.

Vercel MCP now serves both the stateless 2026-07-28 protocol and the 2025 protocol from one endpoint, with mcp-handler 2.x handling the negotiation. The first major hosted MCP server has crossed over - here is what it means for server authors and clients.

MCP Apps shipped with the 2026-07-28 final spec - sandboxed interactive UIs for MCP servers. How they compare to standard tool calling and standalone web UIs, and when to use each approach.

The 2026-07-28 Model Context Protocol spec is the largest revision since launch: a stateless core, deprecated Roots/Sampling/Logging, MCP Apps, Tasks, and tougher OAuth. Here is what breaks, what to adopt, and a migration checklist for server authors and client integrators before the July 28 deadline.

The MCP 2026-07-28 final spec is here - sessions are gone, the protocol is stateless. Here is what changed, what broke, and how to finish migrating your MCP servers.

Build MCP servers that connect Claude to your databases, APIs, and tools. Architecture, TypeScript SDK code, debugging, and the production gaps the spec doesn't cover.

MCP is the open standard for connecting AI apps to tools and data: servers expose tools, resources, and prompts over JSON-RPC, and any client can use them. What it is, how the stateless 2026-07-28 spec works, how to install a server in Claude Code or Cursor, and how to build one with the v2 TypeScript SDK.

An opinionated guide to the MCP server ecosystem in 2026. Curated picks by category, real configuration examples, installation commands, and honest assessments of what works and what does not.

Visual testing tool for Model Context Protocol servers. Like Postman for MCP - call tools, browse resources, and view real-time logs in a browser UI. Zero install via npx.

Lightweight CLI for discovering and calling MCP servers. Dynamic tool discovery reduces token consumption from 47K to 400 tokens. Three subcommands: info, grep, call.

Centralized manager for MCP servers. Connect once to localhost:37373 and access all your servers through a single endpoint. REST API, web UI, and VS Code config compatible.

Registry and hosting platform for MCP servers. 6,000+ servers indexed. One-command install and configuration via CLI. Supports local and hosted deployments.

Largest MCP server directory with 17,000+ servers. Security grading (A/B/C/F), compatibility scoring, and install configs. ChatGPT-like UI for browsing and testing.

Everything you need to know about Model Context Protocol - how it works, how to install servers, how to build your own, and the best ones.

A step-by-step guide to building Model Context Protocol servers in TypeScript. Project setup, tool registration, resources, testing with Claude Code, and production patterns.

MCP servers connect AI agents to databases, APIs, and tools through a standard protocol. Here is how to configure and use them with Claude Code and Cursor.
