🧠 LangFlow MCP High ATS Resume Creator (ATS-Aware)

This repository contains a LangFlow-exported .json file representing a custom multi-agent flow, designed to act as an MCP server. This flow can be used with Claude Desktop or any MCP-compatible client.

Its core functionality is to generate a high ATS (Applicant Tracking System) score resume based on a LinkedIn job post URL and a user’s existing resume. The system parses both sources, summarizes relevant content, and produces a tailored, ATS-friendly resume in multiple formats.

📜 Architectural Decision Records (ADRs)

ADR 001 – Why LangFlow?

LangFlow allows for modular low-code orchestration of agentic LLM pipelines, making it ideal for our goal of chaining multiple agents with custom components and data parsers.

ADR 002 – Why MCP Server?

By exposing this flow as an MCP server:

• It becomes interoperable with Claude Desktop and other MCP clients.
• Users can interact via chat interfaces and benefit from stateful agent behavior.
• Encourages reuse and composability across different workflows.

ADR 003 – Agent Design and Flow

🎯 Agent 1: Resume Summarizer

• Input: User’s current resume (raw text or document)
• Output: Summary of professional experience, total years, key skills, responsibilities, and education.
• ✅ Focused extraction using resume-aware prompt logic.

🎯 Agent 2: Job Description Summarizer

• Input: LinkedIn job post URL via chat.
• Output: Structured summary of required qualifications.
• 🛠️ Powered by a custom LangFlow component that parses HTML directly from the URL input.

🔄 Data Parsing and Conversion

• Each agent’s output passes through a Message-to-Data Converter, followed by a combined parser to normalize structure and prepare inputs for resume generation.

🎯 Agent 3: Resume Generator

• Input: Parsed summaries from Agent 1 & Agent 2.
• Output: ATS-optimized resume in LaTeX format matching job criteria with user’s skills.
• 🧠 Tailored resume structure focused on score improvement.

🛠️ Custom LangFlow Component: Format Converter

• Converts LaTeX output to:
  • ✅ PDF
  • ✅ DOCX
  • ✅ TXT
• Makes the resume instantly downloadable and shareable.

🎯 Agent 4: ATS Score Evaluator

• Input: Generated resume and job summary.
• Output: Final ATS score (out of 100) indicating how well the resume matches the job.
• ✅ Helps users iterate on improvements.
