Overview

AI-generated overview

Lets an assistant score a CV against a job posting, propose a reviewable rewrite, and export the result as PDF or Word.

What it does
Letterin is a remote MCP server for tailoring a CV to a specific job posting. According to its description, it scores how well the CV matches the posting, proposes a rewrite that the user can review before accepting, and exports the finished document as PDF or Word. The manifest does not list individual tool names, so the exact tool set is not documented here.
When to use it
Useful when someone is applying for a job and wants an assistant to compare their CV with the posting, suggest targeted edits, and produce a polished file. It fits job-application workflows rather than general document editing.
Requirements
A remote MCP endpoint at letterin.app over streamable HTTP; nothing runs locally. It requires an Authorization header carrying a bearer key, which the user creates in Letterin under Settings, AI agents (MCP). A Letterin account is implied by that key creation step.
Before you install
The Authorization bearer key is a credential: treat it as a secret and avoid exposing it in logs or shared configuration. The server handles CV content, which is personal data, and sends it to a third-party service. Rewrites should be reviewed before export, since the assistant proposes changes to the document.
