@pvpwire/mcp-server

MCP server for PVPWire: competitive-gaming data for AI agents.

Structured game-mechanics datasets that no other API serves, plus live player and viewer signal, news, and game-economy snapshots.

A thin, typed, sanitized front door over pvpwire.com/api/*. Zero game logic lives here.

Install

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

{
  "mcpServers": {
    "pvpwire": {
      "command": "npx",
      "args": ["-y", "@pvpwire/mcp-server"],
      "env": {}
    }
  }
}

Every free tool works with no auth and no key. Paid tools read a PVPWIRE_TOKEN bought with USDC.

Game data

30 datasets, 7,096 entries, served inside a disclaimer envelope carrying data_version, game_patch, license, and upstream attribution where one is owed. Diablo 2 is independently compiled and verified against at least two sources; Path of Exile and Diablo 3 are compiled with attribution to community sources, with re-expression into PVPWire's own vocabulary in progress; PlanetSide 2 comes from the official Daybreak Census API under Daybreak's published third-party permission; Warzone 2100 is derived from the GPL-2.0 release in which the original publisher open-sourced the game data itself; Xonotic comes from Team Xonotic's own GPL-3.0 balance files; Quake (1996) is compiled from id Software's own GPL-2.0 source; Angband is derived from its GPL-2.0 data tables (PVPWire elects the GPL branch of its dual licence); Diablo 4 aspects are independently compiled from published references, cross-verified against two sources, no game files touched. Sourcing methods for every dataset are published in writing at /api/methods.
