What is the VulnFeed MCP server?

Dependency vulnerability scanner with EPSS scoring. 9 MCP tools. Free tier + x402. The vulnfeed mcp server wraps that behind the Model Context Protocol, so an assistant can use it through 2 defined tools rather than through you.

What it actually does

An MCP server that scans your project dependencies for known vulnerabilities, enriches with EPSS exploit probability scores, and recommends fix versions.

Adding it to your client

The server ships on PyPI as vulnfeed-mcp, so your MCP client can launch it on demand — there is no separate build step. Add the server block to your client's configuration, restart it, and the tools register themselves.

Its toolset

Everything the assistant can do here goes through one of these:

  • Scanning — The Scanning tool exposed by this server
  • Monitoring — The Monitoring tool exposed by this server

Configuration

You will need one environment variable: VULNFEED_API_KEY. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.

Caveats

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
  • MCP clients confirm each tool call by default. Leave that on until you have watched what the vulnfeed mcp server does with a few real requests.

When to reach for it

Among the monitoring and observability options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. VulnFeed's toolset — Scanning, Monitoring — is a fair guide to whether it matches your workflow. It is maintained by infai-tech; worth a glance at recent repository activity before you build anything load-bearing on it.

This entry was verified against VulnFeed's own documentation before publication; SyncDev keeps the directory reviewed rather than auto-generated.

Frequently asked questions

It connects VulnFeed to MCP-compatible AI assistants such as Claude and Cursor, exposing 2 tools (Scanning, Monitoring) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with VulnFeed directly.
