How to Set Up and Use CVE Search
The CVE-Search MCP server connects AI assistants to the CVE-Search API, a comprehensive vulnerability database that aggregates Common Vulnerabilities and Exposures data. It exposes six tools covering vendor enumeration, product discovery, CVE lookups by ID, vulnerability search by vendor/product, retrieval of the 30 most recently updated CVEs, and database status checks. Security researchers and developers use it to perform threat assessments and stay current with newly disclosed vulnerabilities without leaving their AI workflow.
Prerequisites
- Python 3.10 or higher installed
- uv package manager installed (pip install uv or see https://github.com/astral-sh/uv)
- A running CVE-Search API instance (self-hosted) or access to a public CVE-Search endpoint
- An MCP-compatible client such as Claude Desktop, Cline, or Roo Code
Clone the repository
Clone the cve-search_mcp repository to your local machine.
git clone https://github.com/roadwy/cve-search_mcp.git
cd cve-search_mcpInstall dependencies with uv
Use the uv package manager to synchronize the project dependencies declared in the lockfile.
uv syncVerify the server starts
Run the server manually once to confirm it initializes without errors before wiring it into your MCP client.
uv run main.pyAdd the server to your MCP client configuration
Open your MCP client config file (e.g. claude_desktop_config.json) and add the server entry. Replace /absolute/path/to/cve-search_mcp with the actual directory where you cloned the repo.
{
"mcpServers": {
"cve-search_mcp": {
"command": "uv",
"args": [
"--directory",
"/absolute/path/to/cve-search_mcp",
"run",
"main.py"
],
"disabled": false,
"autoApprove": []
}
}
}Restart your MCP client
Restart Claude Desktop or your chosen MCP client so it picks up the new server configuration and connects to the CVE-Search MCP.
CVE Search Examples
Client configuration
Add this block to your claude_desktop_config.json to enable CVE-Search queries. Update the directory path to match your local clone.
{
"mcpServers": {
"cve-search_mcp": {
"command": "uv",
"args": [
"--directory",
"/Users/yourname/cve-search_mcp",
"run",
"main.py"
]
}
}
}Prompts to try
Use these natural language prompts after the server is connected to query CVE data through your AI assistant.
- "List all vendors available in the CVE-Search database."
- "What products does Apache have in the CVE-Search database?"
- "Find all CVEs for vendor 'microsoft' and product 'windows_10'."
- "Look up the details for CVE-2024-21413."
- "Show me the 30 most recently updated CVEs with their CAPEC and CWE data."
- "What is the current database status and when was it last updated?"Troubleshooting CVE Search
uv command not found when starting the server
Install uv first: run 'pip install uv' or follow the instructions at https://github.com/astral-sh/uv. Ensure the uv binary is on your PATH.
Server starts but returns connection errors when querying CVEs
The server queries a CVE-Search API endpoint. Confirm you have a reachable CVE-Search instance. If using a custom endpoint, check the server configuration for any API base URL setting and ensure network access to that host.
MCP client does not show the cve-search_mcp tools
Verify the 'directory' argument in your config file points to the exact folder containing main.py, and that you fully restarted the MCP client after saving the config change.
