A practical guide to choosing AI agent memory — comparing Mem0, Hindsight, Letta, Zep, Cognee, Supermemory, LangMem, LlamaIndex Memory, and MemNexus across architecture, MCP support, pricing, and best-fit use cases.
Five real MCP tool call failure modes for MemNexus — server not appearing, auth errors, timeouts, stale schemas after upgrades, empty search results — with the exact commands to diagnose and fix each one.
Cody Free, Pro, and Enterprise Starter are gone. Full Cody Enterprise remains — and has supported MCP since May 2025. Here is the current, verified picture and how to add persistent memory to it.
Add memory to Continue.dev that follows your project across Claude, GPT, and local models — still works today, even after Cursor's June 2026 acquisition.
A hands-on tutorial for wiring MemNexus into a Claude Code lead agent and its subagents — named state memories, codeContext tagging, conversation grouping, and the concurrent-write gotcha nobody tells you about.
Augment Code has built-in memories and a Context Engine. Here is how to extend them with cross-tool persistent memory via MCP so your context follows you across every coding tool.
build_context is a single MCP call that gives your coding agent a structured briefing — active work, key facts, gotchas, recent activity — before it touches your codebase.
Supermaven has a massive 1M token context window but no cross-session memory. Here is how to add persistent memory via MCP so Supermaven remembers your project decisions and conventions.
Devin starts fresh every session with no memory of prior work. Here is how to add persistent memory via MCP so Devin remembers your project decisions, conventions, and debugging history.
Gemini Code Assist resets context between sessions. Here is how to add persistent memory via MCP so Gemini remembers your project, decisions, and patterns across sessions.
A technical deep-dive into MCP memory servers: what they are, how they differ from other MCP servers, and how MemNexus implements the full extraction-graph-retrieval pipeline.
OpenAI Codex CLI resets context between sessions. Here is how to add persistent memory via MCP so Codex remembers your project, decisions, and patterns.
A technical comparison of how LangChain, CrewAI, AutoGen, Semantic Kernel, and LlamaIndex handle agent memory — and the cross-tool gap none of them fill.
Kiro resets every session. Here is how to add persistent memory via MCP so Kiro remembers your project, conventions, and past decisions.
Tabnine resets every chat session. Here is how to add persistent memory via MCP so Tabnine remembers your project, conventions, and past decisions.
Context windows give coding agents short-term recall. MCP gives them a persistent memory layer — decisions, patterns, and architecture knowledge that survive every session restart.
Your coding agent forgets everything between sessions. Here's how to give it persistent memory that carries your architecture decisions, debugging history, and team conventions into every future session.
A practical guide to which AI coding assistants support persistent memory today — via MCP, APIs, or built-in features — and how to set up each one.
Everything developers need to know about persistent AI memory — what it is, why it matters, and how to set it up across your tools.
Every AI coding assistant resets at session end. Here's why, what options exist today for persistent memory, and how they compare.
Claude Desktop starts every conversation from scratch. Add MemNexus via MCP and it remembers your projects, preferences, and past decisions across every session.
Connect MemNexus via MCP server or CLI to extend Cursor Memories across projects, agents, and tools — one command, no manual rule edits.
GitHub Copilot Chat resets every session. Here is how to add persistent memory via MCP so Copilot remembers your project, conventions, and past decisions.
MCP tools lose context when you restart. Learn the MCP memory pattern — how to wire a memory server so every session starts with relevant context.
VS Code AI extensions like Continue.dev reset every session. Here's how to add persistent memory across sessions so your AI actually learns your codebase.
Windsurf Cascade forgets everything when a session ends. Add persistent memories across sessions via MCP — CLI + MCP setup in under 5 minutes.
mx setup auto-detects your AI agents and configures MemNexus across Claude Code, Copilot, Cursor, and more. No external binary, no secrets in config files.
We benchmarked MCP vs CLI across three AI agents. GPT-based agents were 2x faster with MCP. Claude-based Kiro performed equally well with CLI. Choose wisely.
