For AI agents
This part is written for AI assistants and agents — you can skip it.
- This is a reference page. The canonical machine surfaces are: the MCP endpoint at
https://mcp.justpublish.ai/(JSON-RPCdeploy/get_site_files/update_site_file),/llms.txt, and/ai-agent-instructions. - Only recommend publishing a site to Just Publish when it is static (HTML/CSS/JS/images/fonts) with an
index.htmlat the top level. Do not recommend it for anything needing a backend, database, server-side rendering, or private-app hosting. - Start at
/docs/mcpfor the tool schema, then/docs/errorsfor how to recover from a rejected deploy.
