Stop explaining your project to every new chat.

Nibvine keeps one structured brain per project — the goal, the decisions, the reasons behind them — and hands it straight to Claude Code, Cursor, Codex, or anything else that speaks MCP.

What you keep
  • Feedback loop for solo founders project
    • Positioning
      • Who it is not for
    • Decisions
      • Postgres over SQLite decided
      • No team seats in v1
    • Open questions
      • What anchors the price?

Three moves, and the context stops evaporating

Capture, structure, hand off. The tree does the remembering.

  • Capture without deciding where it goes

    Drop a thought in from the web, or send it to the Telegram bot. Nibvine reads it, proposes the branch it belongs under, and waits for you to confirm before anything lands.

  • Let depth carry the meaning

    Notes nest inside notes. The goal sits at the top, decisions underneath it, the reasoning under those. Tasks, ideas and comments attach to the branch they belong to, so a branch answers a question completely instead of pointing at four other places.

  • Hand the whole thing over in one call

    A context pack assembles the project into a single payload sized for the model's window, summarising branches that are too big and caching the result. Your agent starts every session already knowing the project.

Plug Nibvine into the tools people already code with

One remote MCP endpoint, one scoped token. The connect page writes the config for you; here is what it produces.

  • Claude Code — remote MCP setup for agentic coding and review loops
  • Cursor — repo-native MCP config plus a one-click install link
  • Codex — an exact codex mcp add command, or the TOML snippet
  • VS Code — workspace mcp.json for Copilot agent mode
  • Any MCP client — generic JSON, a smoke test, and the discovery manifest

An agent cannot change your project in one move

Every write from an external tool is staged first. You see exactly what would change, the plan expires if nobody acts on it, and committing applies it in a single transaction that is recorded in the project history.

  • Tokens carry explicit scopes and can be pinned to one project.
  • Tokens are stored as hashes, expire on a date you choose, and revoke instantly.
  • Every change records whether a person, an agent or the system made it.

Two interfaces, one model underneath

Whatever you connect reads the same tree and obeys the same scopes. Both references are generated from the running server, so they cannot drift.

REST API

Projects, notes, the tree, tasks, ideas, comments, quick notes, tokens and change history — for anything that speaks HTTP.

190 endpoints

MCP server

Reads, staged writes and a commit step, described so a model can pick the right one without a wrapper in between.

55 tools

Put one real project in and see.

Ten minutes of notes is usually enough to notice the difference in the next agent session.
