+# xdebug-mcp
+
+Serveur MCP pour analyser des fichiers de profiling Xdebug (format cachegrind).
+
+## Prérequis
+
+- Un fichier de profiling Xdebug (`.gz` ou texte brut) généré avec `xdebug.mode=profile`
+- Optionnel : `make` + Go (pour la compilation locale)
+
+## Sommaire
+
+- [Prérequis](#prérequis)
+- [À quoi sert ce serveur MCP ?](#à-quoi-sert-ce-serveur-mcp-)
+- [Installation](#installation)
+- [Utilisation avec un client MCP](#utilisation-avec-un-client-mcp)
+- [Documentation](#documentation)
+
+## À quoi sert ce serveur MCP ?
+
+`xdebug-mcp` permet à un client MCP d'analyser des fichiers de profiling Xdebug sans outil externe :
+
+- analyse globale d'un profil : stats générales et top N fonctions par coût inclusif ;
+- liste des appelants d'une fonction donnée, triés par coût décroissant ;
+- liste des appelés d'une fonction donnée, triés par coût décroissant.
+
+## Installation
+
+### Option principale : script d'installation
+
+Installer la dernière release publique et lancer l'assistant de configuration :
+
+```sh
+curl -fsSL https://get.lclr.dev/mcp/xdebug/install.sh | bash
+```
+
+### Option alternative : binaire de la dernière release
+
+Télécharger le binaire adapté à votre OS depuis la page des releases publiques :
+
+https://forge.lclr.dev/AI/xdebug-mcp/releases
+
+Puis le rendre exécutable (Linux/macOS) :
+
+```sh
+chmod +x /absolute/path/to/xdebug-mcp
+```
+
+### Option alternative : compilation locale
+
+```sh
+make build
+```
+
+Binaire généré : `build/xdebug-mcp` (ou `build/xdebug-mcp-linux-amd64` selon la cible).
+
+## Utilisation avec un client MCP
+
+### Claude Code CLI
+
+```sh
+claude mcp add xdebug-mcp -- /absolute/path/to/xdebug-mcp mcp
+```
+
+### Configuration JSON
+
+```json
+{
+  "mcpServers": {
+    "xdebug-mcp": {
+      "command": "/absolute/path/to/xdebug-mcp",
+      "args": ["mcp"]
+    }
+  }
+}
+```
