What is the Patch MCP server?

If you already use Patch, the patch mcp server is the piece that lets your assistant work with it directly. Query Microsoft Patch Tuesday security updates (MSRC) with EPSS and CISA KEV enrichment.

What the server does

Ask your AI assistant about Microsoft security updates. This Python-based MCP (Model Context Protocol) server connects AI assistants like Claude, Copilot, and ChatGPT to the MSRC Security Update Guide — the authoritative source for every CVE Microsoft patches — enabling natural-language queries over Patch Tuesday releases: CVEs, KB articles, severity ratings, CVSS scores, affected products, and exploited-in-the-wild status.

  • Get the monthly rollup — - "What did this month's Patch Tuesday fix?"
  • Find what's actively exploited — - "Which vulnerabilities are being exploited in the wild?"
  • Look up any CVE — - "Tell me about CVE-2026-41108" (KBs, affected products, CVSS, description)
  • Map KBs to CVEs — - "Which vulnerabilities does KB5094123 fix?"
  • Filter by product — - "What Critical CVEs affect Windows Server 2022 this month?"
  • Track zero-days — - "Were any publicly disclosed vulnerabilities patched in April?"

Available tools

The toolset is worth reading before you wire it up, because it tells you what the integration is really for:

  • General — The General tool exposed by this server

Installation

Because this one is hosted, setup is mostly authentication — you point your client at the endpoint and approve access. Nothing runs on your machine, so there is no runtime to keep patched.

Credentials and setup notes

Configuration is passed through the environment: MSRC_PROFILES_PATH. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.

Where it fits

Plenty of developer tooling servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Patch's toolset — General — is a fair guide to whether it matches your workflow. It is maintained by jonnybottles; worth a glance at recent repository activity before you build anything load-bearing on it.

We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.

Worth knowing first

  • Your data travels to the provider's service, so the usual questions apply about what you send and what they retain.
  • Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.

Frequently asked questions

It connects Patch to MCP-compatible AI assistants such as Claude and Cursor, exposing 1 tool (General) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with Patch directly.
