Tool-based agent memory: why 2026 benchmarks favor it
Tool-based agent memory exposes store, retrieve, and navigate as callable MCP tools. 2026 benchmarks from Mem0, Memanto, and Wire show why the pattern wins.
Provenance is a context engineering primitive, not a trust score
Retrieval provenance for AI agents isn't an audit log or a trust verdict. It's structural metadata (source, position, time, edges) agents use to plan.
One job per tool: why adding wire_navigate cut agent calls 24%
We restructured Wire's MCP surface from 2 overloaded tools to 3 single-purpose ones. The counterintuitive result: adding a tool cut total calls 24%.
How to build a private AI second brain
Native Notion and Obsidian MCP give every connected agent the same coarse scope. Build a private AI second brain with per-agent, revocable access across tools.
Why multi-agent AI systems fail at context
Up to 86.7% of multi-agent AI runs fail. Most failures trace back to how agents share context, not the agents themselves. Here's why and how to fix it.
Why MCP failures are a context engineering problem
New research analyzed 3,282 MCP bug reports across GitHub. The patterns reveal a context delivery problem, not a protocol problem. Here's what it means.
AI agents have too much access
88% of organizations report AI agent security incidents. The root cause is a context engineering failure: agents get all-or-nothing access, not scoped context.
Your AI Doesn't Remember You. That's by Design.
94% of IT leaders fear vendor lock-in. Every AI tool traps your context in its own silo. Here's why your AI doesn't remember you, and what's changing.
Five Ways to Give AI Access to Your Data
From copy-paste to context platforms, five approaches to giving AI access to your data. Covers security trade-offs, cost, and practical recommendations.
How to Get an MCP Server Without Writing Code
Over 17,000 MCP servers exist but most are generic dev tools. Here's how to create a custom one for your own data without writing a single line of code.
