onecell

Connect onecell to your agent

Your agent reads and writes onecell through MCP: it searches what your team knows, cites it, and saves its work as drafts you check. Pick your agent; most take about a minute, and you sign in through the browser, with no key to copy.

Fastest: run this in a terminal

npx onecell@latest

It finds Claude Code, Codex, Cursor, VS Code, Grok, Gemini CLI, Windsurf and Pi on your computer and sets up each one you pick. Each agent then asks you to sign in. No key needed.

Which agent do you use?

  1. Add the onecell marketplace

    /plugin marketplace add onecell-io/onecell-plugin

    Run this in Claude Code on its own, then the next command.

  2. Install the onecell plugin

    /plugin install onecell@onecell

    One install brings the MCP server and the onecell skills, and keeps the skills current.

  3. Sign in

    Run /mcp, pick onecell and authenticate. Your browser opens to approve; no key needed. Then ask it to list your onecell cells.

  4. Rather not use a plugin?

    Add the server yourself, sign in the same way, then paste the setup prompt from the Another MCP client tab to install the skills.

    claude mcp add --transport http onecell https://onecell.io/api/mcp

Then
