SecureAnnex MCP Server

A Model Context Protocol (MCP) server for analyzing browser extension security. This server provides tools for querying, analyzing, and evaluating security aspects of browser extensions including vulnerability detection, signature checking, code review, and more.

Quick Setup

No manual Python environment setup is needed. This MCP server is designed to work with Claude Desktop, which automatically handles all dependencies using the uv package manager and the included pyproject.toml file.

To get started:

1. Download or clone this repository
2. Make sure the pyproject.toml file is in the project directory
3. Configure Claude Desktop as shown below
4. Optional: If Claude can’t find the uv command, use the absolute path instead, You can find the absolute path by running which uv in your terminal.

Claude Desktop Configuration

Edit ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "secureannex": {
      "command": "uv",
      "args": [
        "--directory",
        "/path/to/secure-annex-mcp",
        "run",
        "secure_annex_mcp"
      ],
      "env": {
        "SECUREANNEX_API_KEY": "your_api_key_here"
      }
    }
  }
}

Note: Replace /path/to/secure-annex-mcp with the absolute path to your SecureAnnex MCP server directory.

Example Usage

Here are some practical examples of how to use the tools with Claude:

Searching for Extensions

# Get all extensions developed by specific developer
I need to find all extensions by [email protected]

# Claude would use:
{
  "name": "search_extensions",
  "arguments": {
    "owner": "[email protected]"
  }
}

Security Analysis

# Get all security signatures for an extension
Show me all security signatures for the AdBlock extension

# Claude would use:
{
  "name": "get_extension_signatures",
  "arguments": {
    "extension_id": "gighmmpiobklfepjocnamgkkbiglidom"
  }
}

# Extract all network domains from an extension
Extract all domains embedded in the AdBlock extension

# Claude would use:
{
  "name": "get_extension_urls",
  "arguments": {
    "extension_id": "gighmmpiobklfepjocnamgkkbiglidom"
  }
}

# Analyze manifest permissions
Show me a table of all permissions requested by AdBlock with explanations

# Claude would use:
{
  "name": "get_extension_manifest_risks",
  "arguments": {
    "extension_id": "gighmmpiobklfepjocnamgkkbiglidom"
  }
}

Integration with Other MCPs

# Leveraging VirusTotal MCP for domain reputation
Can you extract all domains from the AdBlock extension and check their reputation on VirusTotal?

# Claude would use both SecureAnnex and VirusTotal MCPs:
# 1. First, get domains from SecureAnnex
{
  "name": "get_extension_urls",
  "arguments": {
    "extension_id": "gighmmpiobklfepjocnamgkkbiglidom"
  }
}

# 2. Then for each domain, check VirusTotal
{
  "name": "domain_report",  // VirusTotal MCP tool
  "arguments": {
    "domain": "example.com"  // For each domain found
  }
}

# 3. Claude would compile results into a table:
| Domain | Reputation | Detection Ratio | Categories |
|--------|------------|-----------------|------------|
| domain1.com | Clean | 0/85 | Advertising |
| domain2.com | Suspicious | 3/85 | Marketing |

Comprehensive Analysis

# Request a complete security review of an extension
Perform a full security audit of the AdBlock extension

# Claude would combine multiple tools:
{
  "name": "get_extension_details",
  "arguments": {
    "extension_id": "gighmmpiobklfepjocnamgkkbiglidom"
  }
}

{
  "name": "get_extension_vulnerabilities",
  "arguments": {
    "extension_id": "gighmmpiobklfepjocnamgkkbiglidom"
  }
}

{
  "name": "get_extension_analysis",
  "arguments": {
    "extension_id": "gighmmpiobklfepjocnamgkkbiglidom"
  }
}

API Key

The SecureAnnex MCP server requires an API key for authentication with the SecureAnnex API. Obtain your API key from the SecureAnnex service and include it in the Claude Desktop configuration as shown above.

Troubleshooting

If you encounter any issues:

1. Ensure your API key is correctly set in the environment variables
2. Verify the path in your Claude Desktop configuration is correct
