## For Agents
If you are an AI agent, start at [AI onboarding](https://www.cosmicjs.com/docs/ai-onboarding.md). It is the one-page playbook: signup (`POST /v3/agents/sign-up`), MCP, CLI, skills, and which errors to retry.

Every page is also plain markdown: add `.md` to the URL. Example: [https://www.cosmicjs.com/docs/index.md](https://www.cosmicjs.com/docs/index.md).
Full corpus: [https://www.cosmicjs.com/docs/llms-full.txt](https://www.cosmicjs.com/docs/llms-full.txt).
OpenAPI spec: [https://www.cosmicjs.com/openapi.json](https://www.cosmicjs.com/openapi.json).

## Get started
- [Introduction](https://www.cosmicjs.com/docs/index.md): Get an overview of Cosmic and its features.
- [Quickstart](https://www.cosmicjs.com/docs/quickstart.md): Get up and running with Cosmic quickly.
- [AI onboarding](https://www.cosmicjs.com/docs/ai-onboarding.md): One-page playbook for AI agents: POST /v3/agents/sign-up, hosted MCP URLs, the CLI, `npx skills add cosmicjs/skills`, and which HTTP errors to retry.
- [CLI](https://www.cosmicjs.com/docs/cli.md): Install with `npm i -g @cosmicjs/cli`. `cosmic agent-signup` provisions a project; `cosmic objects`, `cosmic types`, and `cosmic media` then run against that bucket.
- [Agent Skills](https://www.cosmicjs.com/docs/agent-skills.md): Agent onboarding for Cosmic: signup flow that provisions a free-tier project + bucket tied to a human email (POST /v3/agents/sign-up), claim via emailed OTP, plus install of the Cosmic SDK rules file for AI coding assistants.
- [MCP Server](https://www.cosmicjs.com/docs/mcp-server.md): MCP server for managing Cosmic content directly through AI assistants. Hosted endpoints at https://mcp.cosmicjs.com/v1/buckets/{bucket-slug} (bucket tools: objects, media, types, AI gen) and https://mcp.cosmicjs.com/v1/agent (signup tools: cosmic_agent_signup, cosmic_agent_verify, cosmic_agent_status). Self-hosted via `npx @cosmicjs/mcp`.
- [CAP](https://www.cosmicjs.com/docs/cap.md): Every Cosmic account is agent-ready. Publish agent.txt and visiting agents can ask your concierge through the Concierge Agent Protocol.
- [Agent Plugin](https://www.cosmicjs.com/docs/agent-plugin.md): The Cosmic MCP server and Agent Skills packaged as one portable Agent Plugin (agent-plugins.org spec 1.0.0), published at github.com/cosmicjs/cosmic-agent-plugin. One install per client for Cursor, VS Code, GitHub Copilot, and Kiro; not yet supported in ChatGPT/Codex. Declares two MCP servers: `cosmic` (stdio via `npx @cosmicjs/mcp`, reads COSMIC_BUCKET_SLUG / COSMIC_READ_KEY / COSMIC_WRITE_KEY from the environment) and `cosmic-signup` (Streamable HTTP at mcp.cosmicjs.c
