Cover letter

ATSPrep's letter builders are rule-based: they assemble a clear letter from what the user gives and leave visible gaps rather than inventing. Web versions: https://atsprep.com/tools/cover-letter-builder and https://atsprep.com/tools/resignation-letter-builder.

How to call ATSPrep

Use whichever is available, in this order:

1. ATSPrep MCP tools. If the ATSPrep MCP server (https://atsprep.com/mcp) is connected, call its tools by name. Some clients add a prefix, e.g. mcp__atsprep__check_resume.
2. The bundled script (needs Node 18+ and network access):

   node scripts/atsprep.mjs <tool> key=value key=@path/to/file.txt
   

   key=@file sends a file's text, which is the safe way to pass a resume or job post. Write the user's text to a file in the current working directory first, and delete it when you're done. node scripts/atsprep.mjs list lists the tools.
3. Plain HTTPS (no Node): POST JSON-RPC to https://atsprep.com/mcp with headers Content-Type: application/json and Accept: application/json, text/event-stream, and the body {"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"<tool>","arguments":{...}}}.

Arguments and limits for every tool are in references/tools.md. What leaves the machine is in references/privacy.md. Tell the user before sending their text to an AI tool the first time.

Cover letter steps

1. Gather the job post (fetch_job_post for a link), the user's resume text and name, and, if they have them, one or two real results with numbers and why they want this company, in their own words.
2. Check draft_cover_letter's arguments in references/tools.md, then call it. Pick style: classic (default), direct, or career-change.
3. Show the letter. Point out any placeholder or thin spot and ask the user for the missing detail rather than filling it in yourself.
4. Polish the wording on request, keeping every fact the user's own. Keep it under one page.

Resignation letter steps

1. Ask for their name, manager, company, role, notice (1w, 2w, 4w or a number of days) and tone (formal, warm or short).
2. Call draft_resignation_letter. It works out the last working day from the date and notice.
3. Show the letter and remind the user to check the notice period in their contract.

Honesty rules

• Never add a number, employer, tool, credential or result the user didn't give you. If a line would be stronger with a number, ask for it.
• Only add a missing keyword if the user confirms they really have that skill.
• AI tool results come back already filtered for made-up facts. Hold your own edits to the same standard.
