ContextsBase
Write specs once, let Claude and Cursor read them every session via MCP
Visit website →About
ContextsBase solves the problem of coding agents reinventing your product truth every session. You write features, business rules, data models, and test cases once in a structured workspace. Your agent — Claude Code, Cursor, Copilot, or any MCP client — pulls them over MCP in a single call and builds from actual specifications instead of guessing.
The workspace organizes context into features, business rules, data entities, Given/When/Then test cases, and design tokens. Agents pull exactly what they need for each iteration step, so two agents never build the same thing. When specs change, ContextsBase flags the code that no longer matches.
Beyond specs, it includes a theme designer for on-brand agent output and a page editor where clicking any element on your live site lets your agent apply changes to the real code. Free for one project with 100 features and 3 team members.

Why we picked it
Every developer who uses coding agents has pasted the same Notion doc into chat for the tenth time. ContextsBase turns that ritual into a single MCP call. The iteration queue — agents claim steps one at a time so they don't collide — is a small idea that solves a real multi-agent coordination problem nobody else is addressing at this layer.
