+# Agent setup
+
+This repository ships a Python MCP server for local Linux workflows.
+
+## Paths on the current host
+
+- Python: `/home/mt2.jakubkadlec.dev/metin/repos/m2pack-secure/.venv-mcp/bin/python`
+- MCP server: `/home/mt2.jakubkadlec.dev/metin/repos/m2pack-secure/mcp_server.py`
+- `m2pack` binary: `/home/mt2.jakubkadlec.dev/metin/repos/m2pack-secure/build/m2pack`
+
+## Codex
+
+Use this MCP server entry:
+
+```json
+{
+  "mcpServers": {
+    "m2pack-secure": {
+      "command": "/home/mt2.jakubkadlec.dev/metin/repos/m2pack-secure/.venv-mcp/bin/python",
+      "args": [
+        "/home/mt2.jakubkadlec.dev/metin/repos/m2pack-secure/mcp_server.py"
+      ],
+      "env": {
+        "M2PACK_BINARY": "/home/mt2.jakubkadlec.dev/metin/repos/m2pack-secure/build/m2pack"
+      }
+    }
+  }
+}
+```
+
+## Claude Code
+
+Use the same stdio server config:
+
+```json
+{
+  "mcpServers": {
+    "m2pack-secure": {
+      "command": "/home/mt2.jakubkadlec.dev/metin/repos/m2pack-secure/.venv-mcp/bin/python",
+      "args": [
+        "/home/mt2.jakubkadlec.dev/metin/repos/m2pack-secure/mcp_server.py"
+      ],
+      "env": {
+        "M2PACK_BINARY": "/home/mt2.jakubkadlec.dev/metin/repos/m2pack-secure/build/m2pack"
+      }
+    }
+  }
+}
+```
+
+## Local verification
+
+```bash
+cd /home/mt2.jakubkadlec.dev/metin/repos/m2pack-secure
+. .venv-mcp/bin/activate
+python scripts/mcp_smoke_test.py
