- List all CVE IDs for a package, optionally filtered by version and ecosystem.
- Query a CVE to retrieve all affected versions of a package.
- Query a CVE to retrieve all versions that fix the vulnerability.
- List currently supported ecosystems with their programming language or OS.
Setting up with Highlight
This MCP is not yet compatible with Highlight’s one-click setup. However, you can still use it with Highlight by following these steps:
- Download and install Highlight from highlightai.com/download
- Navigate to the plugins tab and select "Add Custom Plugin"
-
Configure the plugin with the settings below
Plugin Name

- Enable "Start Automatically" if you want the plugin to start when Highlight launches
From the repository
Install via Smithery (npx -y @smithery/cli install @EdenYavin/OSV-MCP --client claude) or clone locally and configure your MCP host with the provided JSON config (using uv). The server offers four tools: query_package_cve, query_for_cve_affected, query_for_cve_fix_versions, and get_ecosystems.
Claude Desktop / Cursor

Tools Provided
Overview
|name|description| |---|---| |query_package_cve|List all the CVE IDs for a specific package. Specific version can be passed as well for more narrow scope CVE IDs.| |query_for_cve_affected|Query the OSV database for a CVE and return all affected versions of the package.| |query_for_cve_fix_versions|Query the OSV database for a CVE and return all versions that fix the vulnerability.| |get_ecosystems|Query the MCP for current supported ecosystems.Detailed Description
- query_package_cve
- Query the OSV database for a package and return the CVE IDs.
- Input parameters:
- package (string, required): The package name to query
- version (string, optional): The version of the package to query. If not specified, queries all versions
- ecosystem (string, optional): The ecosystem of the package. Defaults to "PyPI" for Python packages
- Returns a list of CVE IDs with their details
- query_for_cve_affected
- Query the OSV database for a CVE and return all affected versions.
- Input parameters:
- cve (string, required): The CVE ID to query (e.g., "CVE-2018-1000805")
- Returns a list of affected version strings
- query_for_cve_fix_versions
- Query the OSV database for a CVE and return all versions that fix the vulnerability.
- Input parameters:
- cve (string, required): The CVE ID to query (e.g., "CVE-2018-1000805")
- Returns a list of fixed version strings
- get_ecosystems
- Query for all current supported ecosystems by the MCP servers.
- Return a dict with the key being the ecosystem name and the value the programming language / OS.
