👋 Introduction

mcp-bugzilla is a Model Context Protocol server for Bugzilla. It lets an AI assistant search, discuss, and manage Firefox/Mozilla bugs through the Bugzilla REST API.

It is read-only without a key; add an API key to create, update, and comment.

✨ Features

• 🔑 Optional auth — read-only without a key; create/update/comment with an API key.
• 🛠️ 17 tools covering bugs, comments, attachments, products, users, fields, and flags.
• 🦊 Mozilla-first — defaults to https://bugzilla.mozilla.org/rest, configurable via env var.
• 🔍 Powerful search — filter by product, component, status, severity, assignee, or quicksearch syntax.
• 💬 Full discussion flow — read comments, post replies, attach work-time logs, and manage comment tags.
• 📎 Attachment management — list, upload, and update patches, screenshots, and logs.
