Expose Claude Code as a production-ready API

MCP servers, tools, and agents, packaged behind a secure, billable endpoint.

Get API endpoint
app.tsx
import { ChuckyClient, tool } from '@chucky.cloud/sdk';

// Tools that run in YOUR browser, called by the sandbox
const showAlert = tool('show_alert', 'Show a browser alert', { message: z.string() },
  ({ message }) => alert(message)
);
const getSelection = tool('get_selection', 'Get selected text', {},
  () => window.getSelection()?.toString()
);

const client = new ChuckyClient({ token, tools: [showAlert, getSelection] });

// Claude runs in sandbox, but calls YOUR browser tools!
await client.prompt('Summarize the selected text and show an alert');

How it works

Think Vercel, but for Claude agents

No server provisioning. No auth system to build. No billing integration. No usage tracking code.

01

Push your repo

Your Claude Code project with MCP servers, custom tools, and skills. We detect your configuration automatically.

02

Get a production API

Your agent runs in a secure sandbox with full access to your codebase, tools, and MCP integrations.

03

Bill your users

Issue JWT tokens with embedded budgets. $0.04/hr compute, zero markup on AI. We handle the rest.

Capabilities

One endpoint, infinite use cases

Same API handles PR reviews, code explanations, migrations, bug hunts. The agent figures it out.

The API can think

Not just execute code — reason through problems, decide what to do, chain multiple steps.

Full codebase context

Your entire repo is loaded. It understands your patterns, your domain, your architecture.

MCP servers & tools

Connect to databases, APIs, external services. Define custom tools that execute in the sandbox.

Multi-turn sessions

Stateful conversations with automatic context management. Claude remembers the full conversation.

Streaming responses

Real-time token streaming for instant feedback. Show partial results as Claude thinks.

Sub-agents & skills

Spawn specialized agents for complex tasks. Reusable prompt patterns and workflows.

Full file & shell access

Read files, write files, run commands, scripts, builds. Not just generate — execute.

Built-in user billing

JWT tokens with embedded budgets. Set daily, weekly, or monthly limits that reset automatically.

The Shift

Not endpoints. Agents.

You're not shipping APIs anymore. You're shipping agents with domain knowledge and real capabilities.

You write logic
Agent reasons through it
Fixed behavior
Adaptive behavior
One function, one job
One endpoint, any task
Context via parameters
Context via codebase
Scales with engineers
Scales with compute
Manual integrations
MCP servers + tools
Rate limiting code
Automatic budget enforcement
Server + browser SDKs
One SDK, runs everywhere

"The repo IS the product. The tools ARE the features. Claude Code IS the backend."
