Can Claude write a cover letter?

Yes for the text. Claude writes a good cover letter from a job post you paste. It can also fill gaps with claims you never made, so check every line. Connect the Resume server (free token) and Claude first checks the posting against your saved profile, then writes a one-page Word letter that states only facts from that profile and leaves a bracketed prompt where it needs more.

What Claude does alone, and what needs the server

Claude on its own

  • Writes a cover letter from a pasted job post.
  • Suggests a tone and an opening line.

With the Resume server

  • A keyword check of the posting against your real profile.
  • A one-page .docx letter with no invented facts.
  • The same profile for every application.

A real call to the live server

We sent this to the hosted server on 2026-11-05. The answer below is the server's own text, not a mock-up. Live values will differ when you ask.

You ask

Here is the Operations Coordinator posting at Northwind Freight. What do I match and miss?

Tool call

tailor_to_job {"job_description":"<the posting, 240 characters>"}

Server answer

{"matched": ["coordinator", "events", "run"], "missing": ["salesforce", "excel", "coordination", "operations", "northwind", "schedules", "budgets", "freight", "reports", "updates", "vendor", "clear", "track", "write", "plan", "two"], "coverage": 16, "advice": "16 of the posting's 19 keywords are absent from your profile. Add them only if they are true: run profile_set with the real skill or bullet. This tool will not write a fact you have not stated."}

The server answers in JSON. These fields are unchanged. The profile and posting are invented examples. coverage is the percent of the posting's keywords found in the profile, here 3 of 19.

You ask

Write the cover letter.

Tool call

cover_letter_create {"company":"Northwind Freight","role":"Operations Coordinator","job_description":"<the posting>"}

Server answer

{"path": "<download link> (valid 1 hour)", "words": 126, "fills_required": ["[add: the requirement from the posting this answers]"], "number_check": "every figure in the letter traces to your profile; no figure from the posting was restated as yours", "note": "This letter states no fact that is not in your profile; anything it did not know was left as a bracketed prompt such as [add: metric]. Fill every [add: ...] prompt before you send this."}

The server answers in JSON. These fields are unchanged. Download links last one hour, so they are shown here as <download link>.
