Long-term memory for coding agents. The sepiace plugin for Claude Code and Codex.
Long-term memory for coding agents. Your agent passes one natural-language sentence, and sepiace remembers, recalls, or forgets. コーディングエージェントのための長期記憶です。エージェントが自然文を1つ渡すだけで、sepiace が覚える、思い出す、忘れるを行います。
If sepiace helps you, a star keeps us going.
[!IMPORTANT] sepiace is in beta. Memories are stored on the sepiace server at hi.sepiace.io, separately for each account. Do not ask your agent to remember passwords, API keys, or other secrets.
It finds Claude Code, Codex, Cursor, VS Code, and OpenCode on your machine, connects the ones you choose, and walks you through signing in. Then start a new session and ask your agent:
- "Remember that I prefer pnpm over npm." - "What did we decide about the release schedule?" - "Forget my old home address."
To bring over what your agent already remembers, run /sepiace:migrate in Claude Code, or ask other clients to use the sepiace-migrate skill. It shows you what it found and sends nothing until you agree.
Other MCP clients: add https://hi.sepiace.io/api/v1/mcp as a remote MCP server (Streamable HTTP). The client signs in through OAuth in the browser.
Your agent writes what it wants in plain words. A judgment network on the server decides whether to save, recall, search, or forget, and combines them when needed. The response contains only memory text, with no IDs, dates, or scores, so the agent spends no tokens building structured arguments.
Each memory is cut from the sentences in the request. No LLM writes or rewrites it, and when something becomes outdated, only that sentence is replaced. A memory stays in the language you wrote it
