Automatically discovers, analyzes, and secures MCP servers integrated with all major Agentic IDEs, Agents and Clients. <br>  ## 💡 Features - **🔍 Auto-Discovery**: Finds known MCP configurations for popular Agentic IDEs like Cursor, Windsurf, VS Code, Claude Desktop, and more - **🔧 Tool, Resource & Prompt Inventory**: Connects to MCP servers and catalogs available tools, resources, and prompt templates - **🛡️ Security Analysis**: Specialized security checks including Prompt Injection, Rug Pull Attack, Cross-server Tool Shadowing, Tool Poisoning, Tool Name Ambiguity, [and more..](#beginner-security-checks) - **🧭 Baseline Drift Detection**: Captures approved MCP components and detects rug pulls attacks - **📊 Comprehensive Reporting**: Generates JSON and Markdown reports with actionable findings - **📜 Audit Trail**: Timestamped baselines and reports for full traceability of changes and findings ## 🧰 Installation ```bash pip install mcp-armor ``` ## 🏃 Quick Start ```bash # Scan all configurations with security analysis (auto-detects baseline.json if present) mcp-armor scan # Inspect configurations and generate baseline (defaults to baseline.json) mcp-armor inspect # Use custom configuration file mcp-armor scan --config /path/to/config.json # Scan multiple configuration files mcp-armor scan \ --config /path/to/cursor.mcp.json \ --config /path/to/vscode.mcp.json # Use custom baseline file path mcp-armor inspect --baseline /path/to/my-baseline.json mcp-armor scan --baseline /path/to/my-baseline.json # Generate markdown report mcp-armor scan --report-type md # Save to custom file mcp-armor scan --output my-report.json mcp-armor scan --report-type md --output my-report.md ``` #### ⚙️ Command Options | Option | Description | |---------------------------|---------------------------------------------------------------------| | `--config` | Custom configuration file path (can be used multiple times) | | `--baseline` | Baseline file for drift detection (scan) or creation (inspect) | | `--report-type {json,md}` | Output format (default: json) | | `--output` | Custom output file path | | `--verbose` | Detailed terminal output | | `--show-logs` | Display debug logs in terminal | ## 🔰 Security Checks ### 🛡️ Standard Checks - **Prompt Injection** - **Indirect Prompt Injection** - **Cross-Server Tool Shadowing** - **Tool Poisoning** - **Prompt Injection in Tool Description, Name and Args** - **Command Injection in Tool Description, Name and Args** - **Tool Name Ambiguity** - **Command Injection** - **Excessive Tool Permissions** - **Hardcoded Secrets** ### 🧭 Baseline Checks Detects deviations from approved MCP components (requires a baseline generated via `inspect` mode): - **Rug Pull Attack** - **Tool Modified** - **Resource Modified** - **Resource Template Modified** - **Prompt Modified** ### 📃 Logging Logs are automatically saved to `logs/mcp_armor.log`: ```bash # Default: logs saved to file only mcp-armor scan # Show logs in terminal too mcp-armor scan --show-logs ``` ### 🧪 Demo Test MCP Armor using our intentionally vulnerable MCP servers.

Inspect and scan modes analyze your MCP configurations, detect MCP servers integrated with your agents, and evaluate them directly on your machine. Prompt injection checks use our open-source model `Aira-security/FT-Llama-Prompt-Guard-2`, downloaded from Hugging Face to your local environment, ensuring your data and code is never shared externally. ### ⚖️ License Distributed under the Apache 2.0 License.
