I Built an MCP Agent Framework for My B.Tech Major Project. It Got 750+ npm Downloads in Week One

Description and use

The Unified MCP Framework was improved by rewriting the README, adding usage examples, better error handling, and OS‑specific installation steps, resulting in over 750 npm downloads in the first week.

Problem

The original MCP framework was functional but unusable due to poor documentation, missing setup guides, and unclear error handling, leading to low adoption.

Outcome

Improved documentation and error handling turned a functional but obscure project into a usable npm package, achieving 750+ downloads in the first week.

Workflow

• 1. Identify usability gaps in the original repo
• 2. Rewrite README from quick‑start to architecture
• 3. Create .env.example with comments
• 4. Separate Windows and Unix Playwright setup paths
• 5. Add QUICK_TEST_QUERIES.md and COMPLEX_TEST_QUERIES.md
• 6. Refactor filesystem error handling to user‑friendly messages
• 7. Polish npm package exports and usage docs
• 8. Add troubleshooting section for common failures
• 9. Publish updated npm package and announce

Evidence

Rewrote the README top-to-bottom: quick-start first, architecture second

Source

Added a proper .env.example with inline comments

Source

Fixed the sandboxed filesystem error handling – instead of a traceback, you now get a clear message: "Access denied: path is outside sandbox directory"

The week the npm package was properly documented and re-announced: 750+ downloads
