Stele

## What is Stele? Stele is shared, persistent project memory for AI coding agents. It keeps one record of what your project decided, what it learned, what can go wrong, and what is being worked on. Claude Code, Cursor, Codex, GitHub Copilot, OpenCode and any other MCP client read it before they act and write back what they find, so a new session, a different tool, or a teammate starts where the last one stopped. ## What agents can do with it - **Recall before acting.** Pull the decisions, lessons and risks that bear on the current task, so an agent does not repeat a mistake the project already made. - **Record as they work.** Save a decision, a lesson or a risk the moment it happens, linked to the component and task it belongs to. - **Coordinate tasks.** Create, claim and complete tasks. Claims are atomic, so two agents never pick up the same work. - **Keep the record true.** A newer decision supersedes an older one, facts can expire or retire when their task closes, and stale entries are flagged for review. - **Trace why.** Walk from a decision back to the task, document and risk behind it. ## Connect Add the server to any MCP client: https://app.stele-ai.dev/api/mcp Sign-in uses OAuth. The first time your client connects, it opens a browser to sign in or create a free account. Setup guides for each client: https://stele-ai.dev/docs/setup-mcp ## Pricing - **Free:** unlimited public projects and one private project. - **Pro:** $12 a month, unlimited private projects. - **Team:** $20 per person a month. Reads and searches are never metered. ## Links - Website: https://stele-ai.dev - Docs: https://stele-ai.dev/docs - Official MCP Registry: `dev.stele-ai/stele`
