Alchemist
Build, test and publish Olbrain AI agents from Claude Code, Codex or claude.ai. You describe the agent; Alchemist, Olbrain's agent builder, plans it, builds it, tests it and asks you before anything goes live.
Install
Claude Code
/plugin marketplace add Olbrain/alchemist-plugin
/plugin install alchemist@alchemistThen run /mcp, pick alchemist and sign in with your Olbrain account. New to
Olbrain? Choose Create account on the sign-in page.
Codex
codex mcp add alchemist --url https://alchemist.olbrain.com/mcp/
codex mcp login alchemistOptional: copy plugins/alchemist/skills/alchemist to ~/.agents/skills/alchemist so
Codex follows the same workflow as Claude.
claude.ai and Claude Code on the web
Add a custom connector with the URL https://alchemist.olbrain.com/mcp/
(Customize → Connectors → Add custom connector; on Team and Enterprise plans an owner
adds it under Organization settings → Connectors). Then click Connect and sign in.
Use it
- Ask in plain words: "Use Alchemist to build an agent that answers questions about our pricing and hands refunds to a person."
/alchemist:build <what the agent should do>starts a build.- "Put my support agent on my website" or "call my intake job when our signup form is sent": Claude adds the chat snippet, or a server route that calls the agent, to your project. It never puts your API key in browser code.
/alchemist:statusshows your account, organisation, builds and any cards waiting on you.
Before Alchemist publishes an agent, makes it live, merges agents or changes how one behaves, it stops with an approval card. Claude shows you the card and waits for your choice, and Claude Code asks your permission before sending it.

Privacy
Every tool call goes to https://alchemist.olbrain.com, which acts as you in Olbrain. It
keeps your Olbrain sign-in encrypted so you stay signed in, and you can end that at any
time by removing the connection.
Once an agent is live, its go-live steps call Olbrain's agent API at
https://webhook.olbrain.com with your organisation's API key: to test it, upload a
file for a job, start a job, or from the server route Claude adds to your app. You run
those commands yourself, and the key stays in your own environment.
