Tool

Install

npm install
node test.mjs        # self-check (pure + live smoke tests)
node index.js        # run the stdio server

Use with an MCP client

Point your client at npx or node in this directory:

{
  "mcpServers": {
    "dnd-5e-mcp": {
      "command": "node",
      "args": ["/absolute/path/to/dnd-5e-mcp/index.js"]
    }
  }
}

Typical flow for an LLM:

  1. build_index once (or let it build lazily).

  2. search_rules to locate a page by name, e.g. "fireball", "fighter", "bag of holding".

  3. get_page with the returned slug, e.g. spell:fireball, fighter, wondrous-items:bag-of-holding.

Notes

  • 2014 rules only. The 2024 ruleset is a separate site (dnd2024.wikidot.com) and is not covered.

  • Page content is extracted from #page-content, tables (wiki-content-table) and TOC blocks handled, converted to Markdown.

  • Fetched pages and the index are cached under .cache/ (git-ignored). Delete it to force a rebuild.

  • No auth needed; the wiki is public.

This server cannot be deployed

One endpoint for every MCP toolRayrun runs every MCP server behind one URL and holds the credentials. Each call is decided per client, tool, and argument, then recorded.ray.runAd
