Nimbalyst Wiki

Nimbalyst Wiki is a free plugin and MCP server that has your coding agents keep a local markdown wiki of decisions, open questions and project context, which you can read and edit in your browser.

Why it matters

For developers who run Claude Code, Codex or Cursor across many sessions, it gives agents a shared place to record what was decided, so context isn't lost between sessions or tools.

Highlights

• Works with Claude Code, Codex (CLI, app and IDE extension), Cursor, VS Code with Copilot agent mode, Claude Cowork and any MCP client, all sharing the same wiki.
• In Claude Code, a setup command has the agent build a Home page, a writing guide and starter pages from your README and docs.
• In Claude Code, reminders tell the agent at session start which wiki pages cover the files you changed, and prompt it to record decisions before the session ends; Codex doesn't run these reminders.
• No Nimbalyst app or account is needed; other tools connect through the nim CLI's MCP server.

Taken from the project's own README, docs or launch page. Claims about speed or accuracy are the maker's unless stated otherwise.

Worth knowing: The MIT license covers the nimbalyst-wiki plugin repo; the license of the separately installed @nimbalyst/cli package was not checked.
