# Today's Best Build: VetCV MCP

**Report Date**: 2026-04-28  
**Coverage**: 2026-04-28T00:00:00+08:00 – 2026-04-28T23:59:59+08:00（UTC）  
**Status**: ok

## Today's Best Build: VetCV MCP

**One-liner**: An open-source MCP server that lints CVs against real ATS parsers and surfaces actionable fixes instead of fake scores.

**Why Now**: Most ATS scanners invent a 0–100 score with no basis in reality. Recruiters at three companies confirmed no universal score exists. As AI agents handle more job applications, a transparent, parser-level linting tool is the only reliable way to optimize a CV.

**Evidence**:
- Existing ATS scanners fabricate scores, confirmed by recruiters at three companies on different ATS platforms. _(signal #6473)_
- GitHub Copilot's shift to usage-based billing shows AI tool costs are becoming granular and unpredictable, making free open-source tools more attractive. _(signal #6348)_
- Most users treat AI like Google search, leading to poor results; structured tools like CV linting provide deterministic, auditable value. _(signal #6493)_

**Fastest Validation**: Deploy the MCP server on a public endpoint and have 5 real job seekers test it against their own CVs, measuring the number of actionable lint items produced per vendor.

**Counter-view**: Unlike Jobscan which uses generic keyword matching, VetCV lints against the actual parsers of Workday, Greenhouse, Lever, Taleo, and iCIMS — a difference confirmed by recruiters who say keyword matching misses the real parsing issues.

## Action Plan

**2-Hour Build**: Fork the existing cv-mirror-mcp repo, set up an Express.js wrapper around the three MCP tools, and host it on a free Railway tier with a simple /health endpoint.

**Why This Wins**: It scratches a real itch: every job seeker needs their CV parsed correctly. It's also a perfect MCP showcase that any agent can adopt, giving it viral potential in the developer community.

**Why Not Alternatives**:
- Building another 'AI wrapper' for resume writing is crowded and low-signal.
- A game to fill LLM wait times is entertaining but not a recurring need like job applications.
- A security tool like GTFOBins is mature; entering that space requires deep expertise.

**Fastest Validation**: Post a Show HN with the hosted MCP endpoint and ask users to paste their issue logs. Measure conversion by how many users run the linter twice.

**Weekend Expansion**: Add a web-based file upload with live lint results, integrate with LinkedIn profile import, and add a 'send to recruiter' share link.
