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.

Microsoft open-sources 86-DOS 1.00, the ancestor of Windows

Microsoft has made the source code for 86-DOS 1.00 available on GitHub to celebrate its 45th anniversary. 86-DOS, developed by Tim Paterson, was foundational for MS-DOS and Windows. This release is part of Microsoft's effort to preserve historically significant software. Microsoft previously released the source code for MS-DOS versions 1.25, 2.11, and 4.0. A team of historians and preservationists has gathered and transcribed DOS-era source listings, including the 86-DOS 1.00 kernel and development snapshots of the PC-DOS 1.00 kernel. Microsoft acquired 86-DOS from Seattle Computer Products for approximately ,000 and modified it to deliver PC-DOS 1.0 in August 1981, which became known as MS-DOS for IBM-compatible computers.

‘Unlimited Attack Vectors’—All Windows Versions At Risk From New Flaw

Microsoft is facing a significant security vulnerability in its Windows operating system known as PhantomRPC, which allows for privilege escalation. Cybersecurity experts have expressed concern over the company's delayed response in issuing a patch for this flaw. The vulnerability resides within the Windows Remote Procedure Call (RPC) architecture and enables processes with impersonation privileges to elevate their permissions to SYSTEM level. Researcher Haidar Kabibo identified five distinct paths for exploitation, which require user interaction, coercion, or compromise of background services. Despite disclosing the vulnerability to Microsoft in September 2025, the company categorized it as moderately severe and did not issue a patch or a Common Vulnerabilities and Exposures (CVE) listing. Microsoft stated that the technique requires an already-compromised machine and emphasized the importance of following security best practices. Experts have criticized Microsoft's lack of action, arguing that it is operationally negligent and places the burden of risk management on users. In the absence of a patch, security professionals recommend focusing on access control and environmental hygiene to mitigate the risks associated with the vulnerability.
