Overview

AI-generated overview

A remote MCP server that lets an assistant search a large CVE and vulnerability database with CVSS, EPSS, CISA KEV, exploit, patch and version data.

What you can do
Search a database of 365k+ CVEs and NotCVEs by identifier or keyword, with severity and scoring context from CVSS and EPSS, plus CISA KEV listing status, known exploits, patches and affected versions.
When to use it
Useful when you need to look up a specific CVE, assess how urgent a vulnerability is, check whether it is actively exploited or in CISA KEV, or find patch and version details during triage or dependency review.
Requirements
A remote streamable HTTP endpoint at notcve.org; OAuth authentication is required. No packages, environment variables or headers are declared.
Before you install
Access requires OAuth sign-in, so the provider sees your account identity and the queries you make. Vulnerability data is third-party intelligence and may be incomplete or out of date; verify before acting on it.

Installation

In SourceWeft

  1. Open NotCVE — CVE & Vulnerability Intelligence in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/org.notcve%2Fvulnerability-intelligence/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

This server asks you to sign in, so SourceWeft could not read its tools without an account and has not indexed them. What a connected account sees can depend on that account and its permissions.

Score

67% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
