Wow Api

An MCP server that gives AI coding assistants first-class access to the World of Warcraft addon API — Blizzard's own generated API documentation, the FrameXML/AddOn UI source code, and the Warcraft Wiki — across all four client flavors:

The API documentation is parsed from Blizzard_APIDocumentationGenerated — the machine-readable docs Blizzard ships with the client — so every C_* function signature, event payload, enum, and structure is exact, typed, and per-flavor. No scraping involved.

Tools

Install

Requires Node 20+. The server is published as @nighthawk42/wow-api-mcp.

Claude Code

claude mcp add wow-api -- npx -y @nighthawk42/wow-api-mcp

Claude Desktop / Cursor / any MCP client (mcpServers JSON):

{
  "mcpServers": {
    "wow-api": {
      "command": "npx",
      "args": ["-y", "@nighthawk42/wow-api-mcp"]
    }
  }
}

From source

git clone https://github.com/Nighthawk42/wow_api_mcp
cd wow_api_mcp
npm ci && npm run build
claude mcp add wow-api -- node /path/to/wow_api_mcp/dist/index.js

Notes:

• The first search_source/get_source_file call per flavor downloads a ~200 MB source checkout into your OS cache dir (one-time, pinned to the same commit the API data was built from).
• Wiki pages are fetched on demand and cached for 24 hours.

Development

npm run dev     # run the server from source
npm test        # vitest (offline)
npm run smoke   # exercise every tool end-to-end (needs network)
npm run ingest  # regenerate data/*.json from wow-ui-source

Data is refreshed weekly by a scheduled GitHub Action that opens a PR when upstream changes. See AGENTS.md for architecture details.
