skillmem MCP server

skillmem is a memory helper for coding agents like Claude Code and Codex. It lets your AI save how it solved a task, remember that skill later, and slowly forget the ones it never uses. It is handy if you work with an AI on code every day and are tired of it starting from zero each time.

What this MCP server does

After a hard task, your AI can write down how it was done as a skill: when to use it, the steps, the outcome, and what it learned. Before the next task, it can search that memory for relevant skills and bring them back into the conversation. When a skill actually helps, for example a test passes or you accept the change, its strength goes up. Skills nobody uses lose strength over time and are moved to an archive, not deleted. Everything stays on your computer in a small database file.

What you can do with it

• Save a skill after a tricky coding task
• Search your saved skills for something relevant
• Recall the best skills for the task in front of you
• Mark a skill as helpful after it works
• Pin an important but rarely used rule so it does not fade
• List and read your saved memories
• Export everything to plain markdown files

Try asking your AI

• “Save what we just did as a skill so you remember it next time”
• “Do you have a skill for fixing failing database migrations?”
• “That fix worked, mark the skill as helpful”
• “Pin the rule about never committing secrets so it never expires”

What it gives back to you

You get back short answers and lists in the chat. A recall gives you the most relevant skills with their trigger and steps. A search gives you matching memories with short previews. When the AI saves or updates something, it tells you what it wrote and under which name.

Who it's for

Developers and technical teams who use coding agents every day and want them to build up useful habits instead of repeating the same mistakes.
