Model Context Protocol (MCP)
The Model Context Protocol (MCP) is an open standard for connecting AI applications to tools and data. An MCP server exposes tools, resources, and prompts; clients like Claude, ChatGPT, Cursor, and VS Code call them.
This page follows the protocol as it evolves: spec releases, notable servers, client support, and the security questions that come with giving models real tools.

MCP Events in ChatGPT: How Event-Driven Agents Actually Work
Until now most agents woke up for only two reasons: a cron schedule or a human message. OpenAI's MCP Events documentation adds a third, a signed webhook from an MCP server. This guide explains the protocol flow, the code you need, the security rules that are easy to miss, and where it fits.
What Is an MCP Rug Pull? Tool Poisoning, Shadowing and How Scanners Work
MCP servers describe their own tools to your agent in plain text, and that text is fetched fresh each session. That one design fact explains tool poisoning, shadowing and rug pulls. This guide defines each attack, walks through a real malicious package, shows what MCP server security scanners can and cannot catch, and gives a checklist.
Top 10 MCP Servers in 2026: 6 Open Source, 4 Closed Source (and What to Check)
The MCP ecosystem is crowded, and the first question for any server is not what it can do but who controls it. This ranking splits ten useful MCP servers into six open-source and four closed, hosted ones, explains how we ranked them, and gives a checklist for connecting any of them safely.
How to Host an MCP Server on ChatGPT Sites
On October 1, 2026 OpenAI staff said you can build and deploy an MCP server through ChatGPT Sites, then restrict it or share it. This is a how-to from that claim plus the Sites and plugin docs: one prompt, save before deploy, access is not directory review.
Claude Plugin Developer Portal: How to Submit, Track, and Ship
Anthropic shipped a dedicated developer portal for Claude plugins on September 26, 2026 — one place to submit a plugin, track its review, and see who's actually installing it. Here is exactly what it does, the two submission paths, and a step-by-step walkthrough from "I have an MCP server" to a live, analytics-tracked plugin.
How to Connect Claude Code to Unity With Unity MCP
Unity's CLI now ships an official Model Context Protocol server, so Claude Code can inspect scenes, create GameObjects, and iterate on a project without you touching the Editor by hand. This guide walks through installing it, configuring Claude Code as a client, verifying the connection, and running your first prompts against a live Unity project.

Pi Adds MCP — Earendil Reverses "No MCP" With CodemodePi.dev used to advertise that it did not support MCP. On September 29, 2026 Earendil shipped MCP in core, wired through Codemode, so agents can compose MCP tools in a harness-side JavaScript sandbox instead of dumping every tool into context. Here is what changed and what to do if you picked Pi for the old "skills + CLI" rule.

Google Opens Home Device Control to Claude and ChatGPT via MCPGoogle launched an MCP server that lets Claude and ChatGPT control Google Home smart-home devices directly — ending years of smart-home control being effectively locked to Google's own Assistant and Gemini, and giving third-party AI assistants a standardized way into one of the largest smart home ecosystems.

Zite MCP: Build Team Apps Through Claude or Cursor, Not Zite CreditsZite, the "agent-native" business app builder, now ships an MCP server at mcp.zite.com that lets any MCP client — Claude, Claude Code, Cursor, ChatGPT — build databases, apps, and workflows directly on a Zite workspace, and doing it this way doesn't touch your Zite credit allowance. Here's what's actually confirmed, what "team apps" means in Zite's own terms, and why this bring-your-own-agent pattern matters beyond one app builder.

Agent Seer: Apple's Method for Turning Your MCP Spec Into an Eval SuiteA new Apple research paper, Agent Seer, synthesizes realistic multi-turn agent evaluation scenarios from nothing but an MCP server's function names, descriptions, and parameter schemas. No hand-written examples, no live tool access, no domain tuning required — and its two findings reshape what "testing an MCP server" should mean.

OpenAI's WebMCP Challenge: Build Agent-Native Web Apps by Sept 3OpenAI opened the WebMCP Challenge on August 25, 2026 with submissions due September 3. WebMCP is an experimental standard that lets a website hand structured tools to a visitor''s AI agent instead of making it click through the UI. This breaks down what it is, how it relates to MCP and the Apps SDK, and what the brief and example apps say a good entry looks like.

Higgsfield in Blender: Prompt-to-Blockout and Camera Moves via MCPOn August 25, 2026, Higgsfield announced a Blender add-on that turns natural language into blockout geometry and camera animation — with manual hand-tuning in between. Available through Higgsfield MCP or the Supercomputer agent stack, it sits at the intersection of agent-driven 3D and the creative workflows explainx.ai has been tracking all summer. Here is what the demo shows, what skeptics flagged, and how it compares to DIY Blender MCP setups.
