### Description (declared)

# MCP-Vault

Model Context Protocol (MCP) server for HashiCorp Vault secret management via claude-vault.

This MCP server exposes Vault operations as tools that Claude Code can use for AI-assisted secret management, while maintaining the existing security model with human confirmation for write operations.

## Features

- ✅ **7 MCP Tools**: Complete Vault operations (login, status, logout, list, get, set, inject)
- 🔐 **Security-First**: Human confirmation required for write operations
- 📝 **Audit Logging**: All operations logged to `.claude-vault-audit.log`
- ⏱️ **Session-Based**: 60-minute token expiry, no persistent credentials
- 🛡️ **Input Validation**: Prevents injection attacks and path traversal
- 🔍 **Pattern Detection**: Scans for dangerous patterns in secret values

## Architecture

```
User authenticates → VAULT_TOKEN exported → MCP server reads env → Claude uses tools
```

**Security Model:**
1. Human authenticates via OIDC + MFA (`source claude-vault login`)
2. Token stored in environment variables (memory only, 60 min TTL)
3. MCP server reads token from environment
4. Write operations require human to type "yes"
5. All operations audited

## Quick Start

### 1. Installation

```bash
cd /path/to/claude-vault/packages/mcp-server

# Install in development mode
pip install -e .

# Or install from PyPI (when published)
pip install claude-vault-mcp
```

### 2. Configure MCP Server (One-time)

**Option 1: Use .mcp.json (Project Scope - Recommended)**

Copy the example configuration:

```bash
# Copy example to your project root
cp .mcp.json.example /your/project/.mcp.json

# Edit to set your Vault address
vim /your/project/.mcp.json
```

Edit `.mcp.json` to point to your claude-vault installation:

```json
