FetchSandbox MCP Launched at Product Hunt #2 Selling 70+ API Sandboxes as a Reproduce-Fix-Prove Loop for Coding Agents
Raj Nagulapalle's FetchSandbox MCP took #2 with 107 votes on Aug 23, offering 70+ API sandboxes wired into Cursor or Claude Code via MCP config. Its claim is narrower and more testable than most agent tooling: reproduce the real integration failure against a sandbox, apply the fix, then re-run to prove the failure is gone, with the tagline 'a receipt, not a vibe.' It targets the gap where an agent's fix passes CI but breaks against a live third-party API, which is the failure mode that makes teams distrust agent-written integration code.
