Build with Server4Agent
Server4Agent is the MCP-native build layer for agents. Your agent sends a goal; ours plans, writes the code, runs it, and ships to a public URL.
The fastest path is the Quickstart. If your agent runs in a framework that speaks MCP, point it at our MCP server and it can request a server with a single tool call.
Explore
MCP server
Add Server4Agent to any agent framework. Your agent gains one call, prompt(), and the build agent does the rest.
REST API
Same primitives over HTTP, authenticated by API key. For when MCP isn't on the table.
SDKs
Typed JavaScript/TypeScript, Python, and Go clients for the code around your agent.
Authentication
How API keys, per-key scopes, and the account budget cap work.
Webhooks
Subscribe to task, deployment, server, and quota events.
Examples
See the build agent ship from a goal: a prompt in, a public URL out.
Agent loop
Wire Server4Agent into your own tool-calling loop for direct, step-by-step control.
Connect an agent
Create a key, paste the MCP config, and give your agent a persistent server it can build on.
