MCP

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.

Hacker News keeps arguing about Claude Code, Codex, skills, MCP, and orchestration. Under the noise, the same four truths keep surfacing: workflows matter more than demos, verification is the bottleneck, skills beat prompts, and orchestration matters more than raw autonomy.

The coding-agent workflow is maturing past giant hand-written prompts. The winning pattern in 2026 is a control stack: project rules, reusable skills, bounded sub-agents, and deterministic tools around the model.

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.

Open-source ChatGPT alternative that runs 100% offline. Desktop app with local models, cloud API connections, custom assistants, and MCP integration. AGPLv3 licensed.

Step-by-step guide to building an MCP server in TypeScript - from project setup to tool definitions, resource handling, testing, and deployment.

MCP servers and function calling both let AI tools interact with external systems. They solve different problems. Here is when to reach for each.

Claude Code Channels let Telegram, Discord, iMessage, fakechat, and custom webhooks push events into a running Claude Code session. Here is when to use them, how the security model works, and where they fit beside Remote Control.

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.
