Code Sandbox API
Run Python, JavaScript, or SQL snippets in an isolated sandbox from your agent while prototyping logic, validating queries, or debugging without polluting your local repo.
Overview
io.github.Br0ski777/code-sandbox is a MCP server for the Build phase that executes Python, JavaScript, and SQL in a remote sandbox for agent-driven coding experiments.
What is this MCP server?
- Executes Python, JavaScript, and SQL in a remote sandbox via MCP
- Remote SSE MCP server at code-sandbox.api.klymax402.com
- x402 micropayment billing for sandbox runs
- Lets agents test algorithms, snippets, and SQL without local interpreter churn
- Version 1.1.0 with published server schema and GitHub source
- Supports 3 languages: Python, JavaScript, SQL
- Server version 1.1.0
- Remote SSE: code-sandbox.api.klymax402.com/mcp
What problem does it solve?
Agents often need to run code to verify ideas, but local execution is slow, risky, or unavailable in locked-down dev setups.
Who is it for?
Builders who want fast, agent-triggered script and SQL trials during feature work without managing a full local runtime for every check.
Skip if: Production workloads, large batch jobs, or teams that require self-hosted sandboxes with custom networking and no per-run micropayments.
What do I get? / Deliverables
You get quick sandbox runs from the agent so snippets and queries are validated before you commit them into your project.
- Executed sandbox results for Python, JavaScript, or SQL inputs
- Faster agent validation loops during implementation
- Reduced need for one-off local interpreter setup
Recommended MCP Servers
Journey fit
Sandbox execution supports active implementation and experimentation during product build, not distribution or production monitoring. It extends what your coding agent can do safely—execute code on demand—which is core agent-tooling in the Build phase.
How it compares
Remote code-execution MCP tool, not a local terminal skill or a full CI/CD pipeline integration.
Common Questions / FAQ
Who is io.github.Br0ski777/code-sandbox for?
Solo builders and agent users who need quick Python, JavaScript, or SQL execution from Claude Code, Cursor, or similar MCP clients.
When should I use io.github.Br0ski777/code-sandbox?
Use it while building when the agent should run small code or SQL experiments to confirm behavior before you merge changes into your app.
How do I add io.github.Br0ski777/code-sandbox to my agent?
Add the remote MCP server URL https://code-sandbox.api.klymax402.com/mcp (SSE) to your agent configuration and complete x402 micropayment setup for the API.
