Guild Wars 2 MCP Server

@pipeworx/guild-wars-2

Guild Wars 2 API v2 MCP — keyless public endpoints (worlds, items, achievements, build, etc.).

Part of Pipeworx — an MCP gateway connecting AI agents to 1476+ live data sources.

Tools

• worlds(ids?) — world list
• items(ids?, page?, page_size?, lang?) — item lookup
• achievements(ids?, page?, page_size?, lang?) — achievements
• professions(ids?, lang?) — professions
• currencies(ids?, lang?) — currencies
• build() — current game build id
• quaggans() — Quaggan images (gag endpoint)
• wvw_matches(world?) — current WvW matches
• commerce_prices(ids?) — bulk trading-post quotes for numeric item IDs (raw copper)
• commerce_listings(ids?) — trading-post order-book depth for numeric item IDs
• guild_wars_2_item_price(name?, item_id?, include_listings?) — live Trading Post price for a single item looked up by name ("Mystic Coin") or by item_id. Returns highest buy order, lowest sell offer, quantity on each side and the spread, each as raw copper and a readable gold/silver/copper string, plus item name, rarity, type and icon.

Pass ids as a comma-sep string ("1,2,3"); omit for index.

Money

Trading Post unit_price values are in copper. 100 copper = 1 silver, 100 silver = 1 gold, so 19944 copper renders as 1g 99s 44c. guild_wars_2_item_price returns both forms.

Item name → ID resolution

The official API has no item-name search: /v2/items/search returns 404, and /v2/items with no ids returns ~70k bare IDs — far too heavy to scan per call. So guild_wars_2_item_price resolves a name in three steps:

1. A curated name → ID map built into the pack (83 commonly traded items — Mystic Coin, Glob of Ectoplasm, T5/T6 fine materials, ores, ingots, wood, leather, cloth, ascended crafting mats, popular runes/sigils, charms/symbols, precursors, agony infusions). Case-insensitive, no extra request. Every ID in it was verified against /v2/items and confirmed to carry a live Trading Post quote.
2. Fallback: api.datawars2.ie — a keyless third-party GW2 item index. This is an added dependency outside ArenaNet's control; its name filter is exact and case-sensitive, so the pack retries with title-cased variants, and the call is bounded by an 8s timeout.
3. If neither resolves, the tool returns {found:false, reason:'item_name_not_resolved', hint} telling the caller to pass item_id — it never guesses a different item.

Account-bound items (Pile of Bloodstone Dust, Charged Quartz Crystal, Mystic Forge Stone, …) have no Trading Post quote and return {found:false, reason:'item_not_traded'}.

Data source

https://api.guildwars2.com/v2 — plus https://api.datawars2.ie for item-name fallback only.

Quick Start

Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):

{
  "mcpServers": {
    "guild-wars-2": {
      "url": "https://gateway.pipeworx.io/guild-wars-2/mcp"
    }
  }
}

What this endpoint actually serves

tools/list at https://gateway.pipeworx.io/guild-wars-2/mcp returns the tools in the table above plus the shared Pipeworx meta-tools — ask_pipeworx, discover_tools, search_within, remember/recall and the rest of the gateway-wide set. So the tool count you see is larger than this table: a single-pack endpoint currently lists roughly 30 shared tools alongside the pack's own. The connection's initialize response states its exact scope, and is the authoritative answer for a given day.

This is deliberate, not multiplexing by accident. The meta-tools are what let a scoped connection answer a question this pack does not cover — via ask_pipeworx, which routes across the whole catalog — without you adding a second MCP server. There is currently no way to mount a pack endpoint without them; if the extra schemas cost you more context than the routing is worth, connect to the full gateway once rather than to several pack endpoints.

Or connect to the full Pipeworx gateway to get every pack's tools listed directly, instead of just this one's:

{
  "mcpServers": {
    "pipeworx": {
      "url": "https://gateway.pipeworx.io/mcp"
    }
  }
}

Both URLs reach the same gateway and the same 1476+ data sources. The only difference is which pack's tools are listed directly; ask_pipeworx reaches all of them from either one.

Using with ask_pipeworx

Instead of calling tools directly, you can ask questions in plain English — this works on the pack endpoint above as well as on the full gateway:

ask_pipeworx({ question: "your question about Guild Wars 2 data" })

The gateway picks the right tool and fills the arguments automatically.
