mcp-facture-electronique-fr 🇫🇷

English | Francais

A Python MCP server exposing the standardized AFNOR XP Z12-013 APIs for the French e-invoicing reform (effective September 1, 2026). This project enables AI agents (Claude, IDEs) to interact natively with the Approved Platform (PA/PDP) ecosystem as a Compatible Solution (SC).

Built on

This package is built on top of mcp-einvoicing-core, a shared base library for European e-invoicing MCP servers. It provides the OAuth2 HTTP client, token cache, shared models, logging utilities, and exception hierarchy used by this package.

mcp-einvoicing-core is installed automatically as a transitive dependency, no extra step is needed.

For contributors: pip install -e ".[dev]" installs the base package from PyPI automatically.

Scope (Compatible Solution)

This server operates in Compatible Solution (CS) mode as defined by the French e-invoicing reform. The CS acts as an intermediary between the company's information system and an Approved Platform (AP/PDP). This means:

• No profile validation of caller-supplied payloads. The server transmits the invoice file (Factur-X PDF/A-3, UBL 2.1, or CII XML) as provided. Structural and business-rule validation (NF XP Z12-012 profiles, Schematron rules) is performed by the receiving Approved Platform, not by this server.
• No e-reporting payload validation beyond schema-level XSD. Transaction reports (Flux 10.1/10.3) and payment reports (Flux 10.2/10.4) are validated against the DGFiP v3.2 XSD schema when validate_ereporting_xml is called, but deeper business-rule checks (e.g. coherence between declared amounts and invoice totals) are the responsibility of the AP.
• No PDF/A-3 envelope generation. The caller must produce the conformant Factur-X PDF/A-3 file with embedded CII XML. This server transmits the finished binary.

The Approved Platform performs final validation and may reject non-conformant submissions with an error code and message.

🏗️ Architecture

The server acts as an intelligent communication interface between your AI agent and the technical infrastructure of the reform:

[ ERP / Business IS ] <--> [ MCP Server ] <--> [ Approved Platform (PA/PDP) ]
          ^                        |
          |                        v
   [ AI Agent (Claude) ] <--- (XP Z12-013 Standard)

🛠️ Exposed services

Text bumped to June 2026 (v1.2.0 swagger current) — AFNOR resupplied the XP Z12-013 narrative text in June 2026 without an updated swagger; the server continues to implement the v1.2.0 wire contract.

Note (FR-XSLT2-1, resolved): the bundled Factur-X 1.09.2 Schematron stylesheets require XSLT 2.0, which lxml/libxslt (XSLT 1.0 only) cannot compile — the same root cause as the DE-XSLT2-1 gap tracked for ZUGFeRD. validate_facturx now runs real Schematron validation via Saxon-HE. Install the optional xslt2 extra for this to work: pip install mcp-facture-electronique-fr[xslt2]. Without it, the tool degrades gracefully to level="unavailable".

Note (FR-FLUX11-2026-06, PPF Annuaire): the directory tools are wired directly against the bundled PPF-platform swagger ppf-openapi-annuaire-api-public-1.11.0-openapi.json — this is a PPF-platform-specific interface, not a PDP-agnostic Annex B abstraction. Per the swagger's own description, these endpoints are subject to change and require prior PISTE application publication before use.

🚀 Installation

Via PyPI (recommended)

pip install mcp-facture-electronique-fr

Or without prior installation using uvx:

uvx mcp-facture-electronique-fr

For Factur-X Schematron validation (validate_facturx, requires the XSLT 2.0 / Saxon-HE backend — see FR-XSLT2-1 above):

pip install mcp-facture-electronique-fr[xslt2]

From source

# Clone the repository
git clone https://github.com/cmendezs/mcp-facture-electronique-fr.git
cd mcp-facture-electronique-fr

# Create the virtual environment
python -m venv .venv
source .venv/bin/activate  # On Windows: .venv\Scripts\activate

# Install in editable mode
pip install -e ".[dev]"

# Initial configuration
cp .env.example .env
# Edit .env with the credentials provided by your PA/PDP

⚙️ Configuration (.env)

The server requires the following variables to authenticate with an Approved Platform (PA):

🤖 Claude Desktop integration

To use this server with Claude, add this configuration to your claude_desktop_config.json file:

{
  "mcpServers": {
    "facture-electronique-fr": {
      "command": "uvx",
      "args": ["mcp-facture-electronique-fr"],
      "env": {
        "PA_BASE_URL_FLOW": "https://api.votre-pdp.fr/flow",
        "PPF_ANNUAIRE_BASE_URL": "https://aife.economie.gouv.fr/ppf/annuaire-public/v1",
        "PA_CLIENT_ID": "votre-id",
        "PA_CLIENT_SECRET": "votre-secret",
        "PA_TOKEN_URL": "https://auth.votre-pdp.fr/oauth/token"
      }
    }
  }
}

⌨️ Cursor integration

Cursor supports MCP servers via stdio. Add the configuration in:

• Global (all projects): ~/.cursor/mcp.json
• Project (this repository only): .cursor/mcp.json

{
  "mcpServers": {
    "facture-electronique-fr": {
      "command": "uvx",
      "args": ["mcp-facture-electronique-fr"],
      "env": {
        "PA_BASE_URL_FLOW": "https://api.votre-pdp.fr/flow",
        "PPF_ANNUAIRE_BASE_URL": "https://aife.economie.gouv.fr/ppf/annuaire-public/v1",
        "PA_CLIENT_ID": "votre-id",
        "PA_CLIENT_SECRET": "votre-secret",
        "PA_TOKEN_URL": "https://auth.votre-pdp.fr/oauth/token"
      }
    }
  }
}

Reload the Cursor window (Ctrl+Shift+P then Reload Window) to apply the changes.

🪐 Kiro integration

Kiro supports MCP servers via its dedicated configuration file. Two levels are available:

• Global (all projects): ~/.kiro/settings/mcp.json
• Workspace (this repository only): .kiro/settings/mcp.json

{
  "mcpServers": {
    "facture-electronique-fr": {
      "command": "uvx",
      "args": ["mcp-facture-electronique-fr"],
      "env": {
        "PA_BASE_URL_FLOW": "https://api.votre-pdp.fr/flow",
        "PPF_ANNUAIRE_BASE_URL": "https://aife.economie.gouv.fr/ppf/annuaire-public/v1",
        "PA_CLIENT_ID": "votre-id",
        "PA_CLIENT_SECRET": "votre-secret",
        "PA_TOKEN_URL": "https://auth.votre-pdp.fr/oauth/token"
      },
      "disabled": false,
      "autoApprove": []
    }
  }
}

The file is automatically reloaded on save. You can also open the config via the command palette (Cmd+Shift+P / Ctrl+Shift+P) then MCP.

Kiro security tip: rather than writing secrets in plain text, use the syntax "PA_CLIENT_SECRET": "${PA_CLIENT_SECRET}", Kiro resolves shell environment variables at startup.
