Overview

decroche-mcp is a deterministic Python/FastMCP MCP server for the complete 360° job-landing pipeline. It exposes pure, testable, zero-LLM tools — the host Claude (guided by the decroche skill) does all the reasoning and rewriting.

Phase 1 (this release): CV anti-rejection core — parse a CV (PDF/DOCX/MD/TXT) into a validated JSON Resume, detect sections, score parse confidence, and expose FR/US market profiles. No magic, no hallucinated metrics, no hidden-text tricks.

Honesty guarantees (hard-coded):

• keyword_gap marks each gap as addable_honestly (real skill, not yet phrased) or genuinely_missing — never invents credentials.
• cv.xyz_scaffold signals missing metrics (y_present: false) and asks for real numbers.
• ats.redflag_scan detects prompt-injection / hidden-text tactics and reports them; never produces them.

Install

# Run as MCP server via uvx (recommended — no install needed):
uvx decroche-mcp

# Or install in a project:
uv add decroche-mcp

# From source:
git clone https://github.com/Casius999/decroche-mcp.git
cd decroche-mcp
uv venv && uv sync --extra dev

MCP Client Config

Add to your Claude Desktop / MCP client config:

{
  "mcpServers": {
    "decroche-mcp": {
      "command": "uvx",
      "args": ["decroche-mcp"]
    }
  }
}

Features — Phase 1

Tool	Description
cv_parse	Parse PDF/DOCX/MD/TXT → JSON Resume + sections + confidence score + warnings
market_get	Get active market profile (FR by default)
market_set	Set active market profile (fr, us, uk, ca-en, ca-fr)
market_available	List available market profile ids

Phase 2+ tools (ATS simulation, match scoring, XYZ scaffold, render, apply queue) come in subsequent tranches. See CHANGELOG.md.

Development

uv venv
uv sync --extra dev

# Lint
uv run ruff check .
uv run ruff format --check .

# Tests with coverage
uv run pytest --cov --cov-report=term-missing --cov-fail-under=80

# Run the server (stdio — attach an MCP client)
uv run decroche-mcp
