ATS Resume Writer — MCP Server

Let your AI agent rewrite resumes that beat applicant tracking systems.

When a user asks Claude, ChatGPT, Cursor, or any MCP-capable agent "tailor my resume to this job posting," this server does the rewrite: keyword-matched to the job description, quantified bullets, ATS-safe structure (Workday, Greenhouse, iCIMS, Taleo) — with strict truthfulness guardrails. The engine never invents dates, metrics, job titles, or seniority levels that aren't in the input resume.

Setup

Get an access code — pay-what-you-want at Gumroad ($0 works; the code arrives in the delivery email along with the full resume kit).

Hosted (no install) — recommended

The server is live as a remote MCP endpoint — connect any Streamable-HTTP-capable client directly:

https://ats-resume-writer-app.vercel.app/api/mcp

Or via Smithery: mutamiri/ats-resume-writer. On the hosted endpoint, pass your access code as the access_code argument to rewrite_resume (no env config needed).

Claude Desktop / Claude Code

{
  "mcpServers": {
    "ats-resume-writer": {
      "command": "npx",
      "args": ["-y", "tsx", "/path/to/ats-resume-writer-mcp/src/server.ts"],
      "env": { "ACCESS_CODE": "your-code-here" }
    }
  }
}

Or after npm run build:

{
  "mcpServers": {
    "ats-resume-writer": {
      "command": "node",
      "args": ["/path/to/ats-resume-writer-mcp/dist/server.js"],
      "env": { "ACCESS_CODE": "your-code-here" }
    }
  }
}

Cursor / other MCP clients

Same shape — stdio transport, ACCESS_CODE in env.

Quick start (development)

npm install
npm run typecheck
npm run build
ACCESS_CODE=your-code npm run test:mcp   # live smoke test against the hosted API
npm run stdio                            # run the MCP server on stdio

How it works

agent ──MCP/stdio──> this server ──HTTPS──> hosted rewrite API ──> Claude
                                            (access code gate,
                                             rate limiting,
                                             truthfulness guardrails)

The server is a thin client: the rewrite engine, rate limiting (10/hour), and guardrails live in the hosted API. Resume content is processed for the rewrite and not stored.

Truthfulness guardrails

The engine refuses to:

• Emit any date not present verbatim in the input

• Invent numbers, percentages, or dollar amounts (unambiguous arithmetic on input numbers is allowed, e.g. "5 days → 2 days" may be restated as "60% reduction")

• Add seniority words ("Senior", "Lead", "Principal", "Director") to job titles the candidate didn't hold

• Compute "X+ years of experience" from work-history dates

A truthful resume without a number beats a fabricated one with a fake number.

Companion kit

The same pay-what-you-want purchase includes the full kit: ATS-safe resume template, 7-step writing guide, 54-bullet quantified bullet bank across 9 roles, cover letter framework with worked examples, LinkedIn checklist, and STAR interview prompts.
