# Olbrain > Olbrain is The Agent OS for Enterprises: an operating system for building, running and governing agent systems that work together, under human oversight and governance. Developers build on it from Claude Code, Codex or Claude.ai through Olbrain Alchemist, Olbrain's agent builder. - An agent system is one or more specialised agents, plus the data, tools, workflows and governance to operate them, built to achieve one defined business objective. - Olbrain Alchemist (alchemist.olbrain.com) is where agents are built and published. Olbrain Noesis (noesis.olbrain.com) runs them. Olbrain Screens (screens.olbrain.com) adds a human workspace where people review, decide or act; headless systems do not need it. - Enterprises build self-serve, with Olbrain's forward-deployed engineers, or together with them (co-build). - Each agent carries a self-identity, and its recorded actions go to an immutable, append-only audit log. Olbrain supplies the trust; the enterprise keeps the accountability. - Current prices are on the Pricing page. Older blog posts and changelog entries are dated history and may quote superseded prices or status. ## Developers - [For developers](https://olbrain.com/developers/): Install Alchemist in Claude Code, Codex or Claude.ai, with the install command for each - [Developer docs](https://docs.olbrain.com): Build agents with Alchemist, then call them from code with the SDKs and webhooks - [Concepts](https://olbrain.com/docs): How Olbrain works: agents, workflows, tools and MCP, knowledge, triggers, identity, the audit log and governance - [Glossary](https://olbrain.com/glossary): Definitions of Olbrain terms - [Changelog](https://olbrain.com/changelog): Dated product milestones and platform updates Install Olbrain Alchemist from a coding agent: - Claude Code: `claude plugin marketplace add Olbrain/alchemist-plugin && claude plugin install alchemist@alchemist`, then run `/mcp` and pick alchemist to sign in - Codex: `codex mcp add alchemist --url https://alchemist.olbrain.com/mcp/ && codex mcp login alchemist` - Claude.ai: add a custom connector named Alchemist with the URL `https://alchemist.olbrain.com/mcp/`, then Connect and sign in ## What Olbrain Alchemist builds The user describes the agent they want in plain words. Alchemist works out the kind of agent, plans it, builds it, tests it and asks before anything goes live. - Chat agents: one person talks to the agent, in chat or by voice, on website chat, WhatsApp or a Shopify storefront - Automatic jobs: run with nobody talking to them, started by a schedule, a webhook (Stripe, Shopify, GitHub, Razorpay, Typeform and others), an email, or a new file in a Google Drive folder. Steps can wait hours or days, stop for a named person's approval, call APIs and notify people - Teams of agents: one front door hands each question to the specialist agent that owns it - Research agents: research the sources and email a report to the person who asked - Tools: connectors including Google Workspace, Notion, Linear, Calendly, Shopify, WooCommerce, SAP HANA and Microsoft Dynamics 365 Finance & Operations, plus any REST API or the business's own MCP server - Knowledge: documents attached to each agent, with a check that it answers from the right file - Quality: a setup review, tests run on the draft before publishing, and reviews of a live agent's real conversations - Not sure what to build: Alchemist asks about the business, suggests agents and writes a requirements document for each Once connected, Alchemist's `alchemist_capabilities` tool returns the full, current list, including what it can't build yet. ## Product - [Platform](https://olbrain.com/platform): What Olbrain is and how it builds, runs and governs agent systems - [Capabilities](https://olbrain.com/capabilities): Agent types and runtimes, tools and connectors, workflows and triggers, orchestration, self-identity, audit, governance, model choice and India hosting - [Pricing](https://olbrain.com/pricing): Current published prices - [FAQ](https://olbrain.com/faq): What Olbrain is, which models it uses, where data is hosted, security, pricing and who builds it - [Trust & security](https://olbrain.com/trust): Security posture, controls, certifications and roadmap - [FP&A agent system](https://olbrain.com/fpna/): An agent system that helps finance teams prepare, explain and explore forecasts - [Implementation](https://olbrain.com/implementation/): How Olbrain works with enterprises to deploy agent systems - [Product demo](https://olbrain.com/demo-video): Video of an agent system built, run and governed end to end - [Discuss your use case](https://olbrain.com/discuss): Contact Olbrain about an enterprise deployment ## Research - [Whitepapers](https://olbrain.com/whitepaper): Olbrain's research papers on agent identity - [CNE-Protocol](https://olbrain.com/whitepaper/cne/): Agent identity defined by Coherence, Narrative Continuity and Exclusivity - [Formal foundations of the CNE-Protocol](https://olbrain.com/whitepaper/cne-mth/): The mathematical treatment: definitions, conditions and theorems - [Coherence](https://olbrain.com/whitepaper/coherence/): The C in CNE, and what an auditor can do with the record - [Labs](https://olbrain.com/labs): Olbrain Labs research into self-identity, the CNE Protocol and the verifiable record ## Company - [Approach](https://olbrain.com/approach): The principles behind how Olbrain works - [Customers](https://olbrain.com/customers): Where Olbrain is deployed today - [Recognition](https://olbrain.com/recognition): Research citations, benchmarks, listings and government recognition - [Press](https://olbrain.com/press): Press kit, brand assets, founder bios and official descriptors - [Media kit](https://olbrain.com/media): Company facts, leadership bios and brand assets - [Contact](https://olbrain.com/contact/): How to reach Olbrain ## Optional - [Blog](https://olbrain.com/blog): Essays on agency, identity and the architecture of AI agents - [Investor information](https://olbrain.com/memo/): The investor memo - [Careers](https://olbrain.com/careers): Open roles - [Privacy policy](https://olbrain.com/privacy.html) - [Terms of service](https://olbrain.com/terms.html) - [Refund policy](https://olbrain.com/refund.html)
