Ghost: A Database for Our Times?

Ghost, developed by ghost.build, is an "agent-first" Postgres database platform designed for AI-related applications, allowing developers and AI agents to create, fork, inspect, query, manipulate, and delete databases easily. It is free to use and hosted on Ghost’s Cloud infrastructure, making it suitable for testing, prototyping, and disposable database environments. Users can create databases on demand, execute SQL queries, and discard them when finished, contrasting with traditional managed databases. Ghost integrates with AI tools like Codex and Claude Code, providing direct database management capabilities through its MCP server. To install Ghost, users need a supported coding agent and a GitHub account. Installation commands differ for Linux, macOS, and Windows. After installation, users can verify the Ghost MCP server and interact with it through their coding agents. Examples of using Ghost include creating a sales data database, utilizing Ghost CLI commands, and experimenting with databases through AI agents. Ghost allows for rapid database manipulation and is ideal for proofs of concept and experimentation, although caution is advised before using it for production data.

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.

Why developers are betting on Postgres for AI

Organizations are intensifying the development of AI applications and agents, which rely on access to existing enterprise data to avoid inaccuracies in responses, a phenomenon known as "hallucination." Jensen Huang, CEO of Nvidia, and Phillip Merrick, co-founder of pgEdge, emphasize that structured data is essential for AI effectiveness. PostgreSQL is highlighted as a preferred database for AI applications, with 66% of respondents in the Stack Overflow 2025 Developer Survey indicating they wish to continue using it. Merrick notes PostgreSQL's advantages, including its open-source model, scalability, and ability to handle both structured and unstructured data. The pgEdge toolkit supports the entire lifecycle of AI application development, including document ingestion and vector embedding generation. PostgreSQL offers deployment flexibility and robust security features, making it suitable for critical sectors like finance and healthcare.

Microsoft confirms AI agents are still coming to the Windows 11 taskbar as it prepares for public rollout

Microsoft is integrating AI agents into the Windows 11 taskbar, allowing users to invoke these agents, including third-party options, directly from the taskbar. This feature will be optional and not enabled by default. The AI agents, such as Microsoft 365 Researcher, can operate autonomously to perform tasks like planning, researching, and executing actions without user intervention. Users can activate these agents by hovering over the Microsoft 365 Copilot icon on the taskbar. The Microsoft 365 Researcher can conduct complex research tasks and generate reports using files from OneDrive or Microsoft 365, but it requires a Microsoft 365 subscription to access. A new feature called ‘Ask Copilot’ may enhance the search experience by allowing users to tag and trigger agents using the “@” symbol. This functionality is supported by the Model Context Protocol (MCP), which connects AI models with applications and files. Developers can integrate their agents using the Windows.UI.Shell.Tasks API. Despite earlier statements about reducing AI in Windows 11, Microsoft is adopting a more selective approach to AI integration, ensuring that the use of taskbar agents remains optional and not intrusive. The company is phasing out Copilot branding in certain applications while maintaining AI capabilities in a streamlined manner.
