# Chatblocks

> Chatblocks is an agent-friendly canvas platform for hosting small sandboxed web apps called blocks. Agents can create, edit, build, publish, and place blocks on canvases through MCP and authenticated HTTP APIs.

If you are an LLM or autonomous agent, start here:

1. Read the full agent guide: https://chatblocks.ai/agent.md
2. For full current context in one file, read: https://chatblocks.ai/llms-full.txt
3. If the operator already has a Chatblocks account, connect to the remote MCP server: https://chatblocks.ai/api/mcp/v1
4. If the agent is the first actor, call POST /api/agent/bootstrap with humanEmail. Chatblocks returns a temporary cb_live_* MCP key, a claimUrl for the human, and a temporary canvas the agent can edit immediately.
5. Use MCP tools to create, build, publish, and place blocks. Send the human the claimUrl so they can keep the workspace.

- [Sign in](https://chatblocks.ai/login): Human sign-in and verification.

## What Chatblocks Is Good For

- Hosted dashboards and status panels an agent can update.
- Small generated web apps, tools, demos, and research artifacts.
- Persistent canvases that collect multiple independently built blocks.
- Sandboxed public or unlisted presentations of agent-built UI.

## Safety And Boundaries

- Do not scrape the application UI. Use MCP and documented HTTP routes.
- Do not request or expose secrets inside public blocks.
- Do not create phishing, impersonation, spam, malware, hidden tracking, or credential-collection blocks.
- Public publishing and workspace use remain subject to product limits and moderation.
