Inside the Architecture of an MCP Server for PostgreSQL

The Model Context Protocol (MCP) serves as a standard interface between large language models (LLMs) and external systems like PostgreSQL, emphasizing the importance of control over mere connectivity. An MCP server must act as a mediation and policy layer, enforcing security boundaries and ensuring that connections default to read-only. It should validate AI-generated SQL as untrusted input, encapsulate queries within transactions, and apply execution-time controls. The server must separate query generation from execution approval to manage operational costs and enforce guardrails on query types, such as limiting the number of rows returned. Token efficiency is crucial, with design considerations for compact data representation and schema introspection. In production, connection management is vital to prevent data leakage among multiple AI agents, and observability through logging executed queries and metadata is necessary for debugging and compliance. Long-running sessions require support for paginated responses to manage context effectively. Overall, the MCP server must integrate security, query safety, token efficiency, and observability into its design from the outset.

Android officially releases AI development skills, enabling you to build Android apps up to 3 times faster using AI agents.

Google has introduced a suite of AI skills and development tools for Android developers to enhance productivity, allowing them to build applications three times faster using any AI agent. The documentation has been restructured into a format called Agent Skills, providing clear, actionable steps for AI to follow, which eliminates the need for manual input from developers. Google plans to expand its offerings with more official Android skills compatible with community-developed skills. Additionally, a preview of the Android CLI has been released, enabling developers to perform tasks like environment setup and project creation directly from the terminal, significantly improving efficiency. Internal tests show that using the Android CLI with the new skills can reduce AI token usage for project setup by 70% and decrease task completion time to a third of traditional methods. The Android Knowledge Base has also been introduced to keep AI agents updated with current data, enhancing their effectiveness. Developers can transition from the Android CLI to Android Studio for advanced debugging, with new AI-powered project flows integrated into the IDE.

Russia sees WeChat, Douyin as models for its homegrown Max messenger

Russia is developing the Max messaging application, inspired by Tencent's WeChat and Douyin, to compete with Telegram. The Kremlin is promoting Max as an alternative to Telegram, which has faced user resistance due to perceived limitations in functionality. Kiriyenko, CEO of VK, highlighted that Max will adopt an open platform model similar to WeChat, integrating third-party chatbots, and noted that 500,000 companies have already registered on the platform. The Russian government aims to establish a robust "platform economy" to boost economic growth, leveraging partnerships and innovative services. Kiriyenko also expressed interest in utilizing Douyin's e-commerce strategies involving short video content.

Perplexity is changing its wake word from ‘Hey Plex,’ and here’s the proof

Users of the Samsung Galaxy S26 reported issues with the integration of Perplexity AI, specifically that the app was missing from the voice wake-up list and the wake word "Hey Plex" was not functioning. Samsung described the situation as part of an "ongoing product refinement process" but did not clarify the cause. Perplexity CEO Aravind Srinivas hinted at a transition to a new wake word, "Hey Perplexity," which is supported by an update to the Perplexity Android app (version 2.81.2) that prepares for this change. The app is being updated with screens related to the new command, indicating that the transition is in progress. Speculation suggests that the change may be to differentiate from the Plex media service and address potential pronunciation challenges. An APK teardown can provide insights into future features, but there is no guarantee they will be included in a public release.

Claude Code and Cowork now let Anthropic’s AI take control of your Mac or Windows desktop

The feature allowing Claude to control user desktops is now available to Pro and Max users within the Windows application for Claude Code and Claude Cowork. This capability enables Claude to manage tasks on a user's computer, initially utilizing existing integrations like Slack and calendars before taking direct control when necessary. The functionality was previously available as a research preview for macOS users. The development is partly due to Anthropic's acquisition of Vercept AI, which specializes in AI-driven computer management. Despite its potential, there are concerns regarding reliability, security, and data privacy that need to be addressed before a broader rollout.

EDB Postgres® AI Delivers Superior Predictability vs. Cloud Data Warehouses in High-Concurrency Benchmark, Unveils Q1 Platform Updates to Power the Agentic AI Era

Independent benchmarking by McKnight Consulting Group shows that EDB Postgres AI for WarehousePG provides significant cost efficiency and performance consistency, with organizations potentially saving up to 58% in total cost of ownership compared to leading cloud data warehouse solutions. The evaluation compared EDB PG AI against competitors like Snowflake, Databricks, Amazon Redshift, and Hive on Apache Iceberg using a 10TB extended TPC-DS dataset, focusing on high-concurrency mixed workloads. Key findings include: - EDB PG AI demonstrated unmatched cost efficiency, with an annual cost of ,886 compared to Snowflake’s ,953 for a multi-cluster setup. - It exhibited superior concurrency handling, with the lowest performance slowdown of 2.7x when scaling from one to five concurrent users, outperforming Snowflake (3.9x), Redshift (4.0x), and Databricks (4.1x). - EDB PG AI's core-based, capacity-pricing model eliminates unpredictable pricing fluctuations associated with consumption-based models. EDB announced Q1 2026 platform updates, including: - GPU-Accelerated Analytics for 50–100x faster analytics on large datasets. - Enhanced Agent Studio for quicker AI agent development and deployment. - Upgraded Vector Engine for improved indexing speed and efficiency. - WarehousePG Enterprise Manager for simplified management of MPP workloads. - Agentic Database Management with a native chatbot for natural language database management. - Certification as a mission-critical data layer for the Red Hat Ansible Automation Platform.
