This connects Claude to FIRST.org's Exploit Prediction Scoring System, which estimates the probability that a CVE will be exploited in the wild. It's part of the Pipeworx gateway ecosystem but available as a standalone endpoint. The source doesn't list specific tools, but EPSS typically lets you query probability scores by CVE ID and pull bulk scoring data. Reach for this when you're doing vulnerability prioritization work and want to factor in real world exploit likelihood instead of just CVSS severity. You can call tools directly or use the ask_pipeworx wrapper to query in plain English. Runs over streamable HTTP, so no local setup needed.
FIRST.org EPSS (Exploit Prediction Scoring System) MCP.
Part of Pipeworx — an MCP gateway connecting AI agents to 776+ live data sources.
| Tool | Description |
|---|
Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):
{
"mcpServers": {
"epss": {
"url": "https://gateway.pipeworx.io/epss/mcp"
}
}
}
Or connect to the full Pipeworx gateway for access to all 776+ data sources:
{
"mcpServers": {
"pipeworx": {
"url": "https://gateway.pipeworx.io/mcp"
}
}
}
Instead of calling tools directly, you can ask questions in plain English:
ask_pipeworx({ question: "your question about Epss data" })
The gateway picks the right tool and fills the arguments automatically.
