SandboxAPIs

Overview

SandboxAPIs is a Model Context Protocol server that provides drop-in read-only replicas of GitHub, Jira, Slack, and 18 other services. Each replica comes preloaded with a fake company, letting you test and develop against realistic data without touching production systems or needing real credentials.

The server runs entirely on your machine via the npm package @sandboxapis/mcp, which communicates with MCP clients over stdio. Installation is instant with npx -y @sandboxapis/mcp, requires no authentication, and needs no external configuration. The latest release is v0.3.13. Full documentation is available at https://sandboxapis.dev/docs/mcp.

SandboxAPIs appears in the Version Control category on mcp.site and works with Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and other MCP clients. If you maintain this server, claim your listing to earn a Verified badge and keep information up to date.
