Developer Guide: Build a Production-Ready MCP Server With Postgres in 15 Minutes

·1 views

A technical walkthrough published on DEV Community outlines how to build a functional Model Context Protocol (MCP) server backed by a Postgres database, contrasting the approach with typical demo-only Node SDK tutorials. The guide uses Air Pipe for hosting and configuration, requiring only a database connection string, a single config file, and a generated secret token to get started. Developers can use any Postgres provider — including Neon, Supabase, or a local Docker instance — as long as they have a valid connection string. The schema involves three tables covering tenants, token metadata, and a sample tasks resource, with the tasks table designed to be swapped out for real application data. The entire setup is estimated to take around 15 minutes and is intended to produce a server suitable for real customer use rather than just local experimentation.

Run Qwen 3 as a Free Local AI Coding Assistant Inside VS Code Using Ollama

Developers can set up a free, offline AI coding assistant in Visual Studio Code by combining Alibaba's open-source Qwen 3 language model with the Ollama runtime. Ollama allows large language models to run directly on a local machine, eliminating cloud dependencies, API costs, and privacy concerns. After installing Ollama and pulling the Qwen 3 model, users connect it to VS Code via a local endpoint, typically at localhost:11434, using a tool called OpenCode. The setup supports tasks such as code generation, debugging, refactoring, and explanation across languages like JavaScript and React. Effective use of the local model depends on writing focused, incremental prompts rather than requesting entire applications at once.

Dev Team Restyled a Third-Party React Plugin for Austrian Animal Shelter Without Editing Its Code

A developer working for Austrian animal shelter Arche Noah built a CSS and vanilla JavaScript augmentation layer to reshape a commercial WordPress plugin's React app without modifying its source code. The plugin, which pulls pet adoption data from an external SaaS called Pet-Manager, had design inconsistencies and missing UI elements that needed fixing for the shelter's audience. Because the plugin updates would overwrite any direct changes and the React bundle is minified, the team used a MutationObserver-based approach to modify the app from the outside. A key lesson emerged when React's reconciliation process silently broke the UI after users navigated between animals, caused by the team moving DOM nodes that React believed it owned. The solution was to hide unwanted elements rather than remove them, and to append new custom nodes instead of reparenting React's own, ensuring changes survived repeated re-renders.

CopilotKit Launches Channels SDK to Deploy AI Agents Across Slack, Teams and More

CopilotKit has released the Channels SDK, an open-source TypeScript library that lets developers deploy any AG-UI-compatible AI agent to messaging platforms such as Slack, Microsoft Teams, Discord, Telegram, and WhatsApp from a single codebase. The SDK eliminates the need to rebuild platform-specific integrations repeatedly, handling webhooks, message formatting, durable state, and delivery retries under the hood. It is built on the AG-UI protocol, keeping the app and agent decoupled, which means developers can swap agent frameworks — including LangChain, Google ADK, or Pydantic AI — without rewriting channel code. A managed production path is available through CopilotKit Intelligence, removing the need for a public URL while handling connections and message delivery. Developers can try a live demo on Slack and Microsoft Teams via copilotkit.ai/try-channels, or clone the open-source OpenTag project on GitHub to get started.

DOGE Budget Cuts to Forest Service Raise Wildfire Response Concerns

Recent federal budget cuts driven by the Department of Government Efficiency (DOGE) have targeted the U.S. Forest Service, reducing its staffing and resources. Critics warn that these reductions could hamper the agency's ability to manage and respond to wildfires. The cuts come as wildfire season intensifies across parts of the United States, raising alarm among conservation and forestry experts. Outdoor Life reported that the timing of the reductions is particularly concerning given the increased frequency and severity of recent wildfire events. Advocates argue that underfunding forest management agencies creates long-term risks for both public safety and natural ecosystems.
