Postgres MCP Server: Setup, Tools, and Safe Query Access
A practical guide to running a Postgres MCP server — which implementation to pick, how to wire it into Claude Desktop, Cursor, and VS Code with Docker, what tools it exposes, and how to give an agent query access without handing it your database.

Agent Memory: Architecture, Types, and Trade-Offs
Agent memory is four things, not one — working, episodic, semantic, and shared. Most writing covers the first three, which are private to a single agent over time. The hard case is shared memory: state that concurrent agents read and write in the same window.

Agentic Commerce: How Shopping Agents Actually Buy
Agentic commerce fails at the gates, not the recommendations. Walk the six steps a shopping agent executes — discovery, cart, price, promotion, inventory, spend authorization — and see which ones break when concurrent agents read four systems at four different moments.
Boyd Stowe|Sep 11, 2026Agentic AI Architecture: Patterns and What Breaks in Production
Agentic AI is easy to prototype and hard to run. The architecture is well understood — autonomy, tool use, multi-step planning, memory, arranged into a few reference patterns. What is not well understood is what breaks once those patterns meet concurrency and time: an agent acting on state it read nine steps ago, two agents committing against the same mutable state with no human between them. This is the architectural treatment, including the honest part — most agentic workloads don’t have this problem at all.
Xiaowei Jiang|Sep 10, 2026MCP Server Architecture: How It Works, and What It Can’t Do
An MCP server exposes tools, resources, and prompts to an AI agent over a standard protocol, replacing custom integrations with one interface. This guide covers the primitives, the transports, and the full request flow — then the part the spec is silent on: MCP standardizes how an agent reaches context, not whether that context is current or whether two tool calls in the same reasoning step saw the same state.

Claude for Commerce gives merchants an agentic commerce build in weeks. Its guardrails stop the agent from inventing a price. Nothing in the blueprint stops it from quoting a real price that stopped being true ninety seconds ago.
